It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations -below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it -becomes a de-facto standard. To achieve this, non-free programs must -be allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control -compilation and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at least - three years, to give the same user the materials specified in - Subsection 6a, above, for a charge no more than the cost of - performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply, and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License -may add an explicit geographical distribution limitation excluding those -countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms -of the ordinary General Public License). - - To apply these terms, attach the following notices to the library. -It is safest to attach them to the start of each source file to most -effectively convey the exclusion of warranty; and each file should -have at least the "copyright" line and a pointer to where the full -notice is found. - - - <one line to give the library's name and a brief idea of what it does.> - Copyright (C) <year> <name of author> - - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - This library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU - Lesser General Public License for more details. - - You should have received a copy of the GNU Lesser General Public - License along with this library; if not, write to the Free Software - Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - -Also add information on how to contact you by electronic and paper mail. - -You should also get your employer (if you work as a programmer) or -your school, if any, to sign a "copyright disclaimer" for the library, -if necessary.

Distribution Obligations. - - 3.1. Application of License. - The Modifications which You create or to which You contribute are - governed by the terms of this License, including without limitation - Section 2.2. The Source Code version of Covered Code may be - distributed only under the terms of this License or a future version - of this License released under Section 6.1, and You must include a - copy of this License with every copy of the Source Code You - distribute. You may not offer or impose any terms on any Source Code - version that alters or restricts the applicable version of this - License or the recipients' rights hereunder. However, You may include - an additional document offering the additional rights described in - Section 3.5. - - 3.2. Availability of Source Code. - Any Modification which You create or to which You contribute must be - made available in Source Code form under the terms of this License - either on the same media as an Executable version or via an accepted - Electronic Distribution Mechanism to anyone to whom you made an - Executable version available; and if made available via Electronic - Distribution Mechanism, must remain available for at least twelve (12) - months after the date it initially became available, or at least six - (6) months after a subsequent version of that particular Modification - has been made available to such recipients. You are responsible for - ensuring that the Source Code version remains available even if the - Electronic Distribution Mechanism is maintained by a third party. - - 3.3. Description of Modifications. - You must cause all Covered Code to which You contribute to contain a - file documenting the changes You made to create that Covered Code and - the date of any change. You must include a prominent statement that - the Modification is derived, directly or indirectly, from Original - Code provided by the Initial Developer and including the name of the - Initial Developer in (a) the Source Code, and (b) in any notice in an - Executable version or related documentation in which You describe the - origin or ownership of the Covered Code. - - 3.4. Intellectual Property Matters - (a) Third Party Claims. - If Contributor has knowledge that a license under a third party's - intellectual property rights is required to exercise the rights - granted by such Contributor under Sections 2.1 or 2.2, - Contributor must include a text file with the Source Code - distribution titled "LEGAL" which describes the claim and the - party making the claim in sufficient detail that a recipient will - know whom to contact. If Contributor obtains such knowledge after - the Modification is made available as described in Section 3.2, - Contributor shall promptly modify the LEGAL file in all copies - Contributor makes available thereafter and shall take other steps - (such as notifying appropriate mailing lists or newsgroups) - reasonably calculated to inform those who received the Covered - Code that new knowledge has been obtained. - - (b) Contributor APIs. - If Contributor's Modifications include an application programming - interface and Contributor has knowledge of patent licenses which - are reasonably necessary to implement that API, Contributor must - also include this information in the LEGAL file. - - (c) Representations. - Contributor represents that, except as disclosed pursuant to - Section 3.4(a) above, Contributor believes that Contributor's - Modifications are Contributor's original creation(s) and/or - Contributor has sufficient rights to grant the rights conveyed by - this License. - - 3.5. Required Notices. - You must duplicate the notice in Exhibit A in each file of the Source - Code. If it is not possible to put such notice in a particular Source - Code file due to its structure, then You must include such notice in a - location (such as a relevant directory) where a user would be likely - to look for such a notice. If You created one or more Modification(s) - You may add your name as a Contributor to the notice described in - Exhibit A. You must also duplicate this License in any documentation - for the Source Code where You describe recipients' rights or ownership - rights relating to Covered Code. You may choose to offer, and to - charge a fee for, warranty, support, indemnity or liability - obligations to one or more recipients of Covered Code. However, You - may do so only on Your own behalf, and not on behalf of the Initial - Developer or any Contributor. You must make it absolutely clear than - any such warranty, support, indemnity or liability obligation is - offered by You alone, and You hereby agree to indemnify the Initial - Developer and every Contributor for any liability incurred by the - Initial Developer or such Contributor as a result of warranty, - support, indemnity or liability terms You offer. - - 3.6. Distribution of Executable Versions. - You may distribute Covered Code in Executable form only if the - requirements of Section 3.1-3.5 have been met for that Covered Code, - and if You include a notice stating that the Source Code version of - the Covered Code is available under the terms of this License, - including a description of how and where You have fulfilled the - obligations of Section 3.2. The notice must be conspicuously included - in any notice in an Executable version, related documentation or - collateral in which You describe recipients' rights relating to the - Covered Code. You may distribute the Executable version of Covered - Code or ownership rights under a license of Your choice, which may - contain terms different from this License, provided that You are in - compliance with the terms of this License and that the license for the - Executable version does not attempt to limit or alter the recipient's - rights in the Source Code version from the rights set forth in this - License. If You distribute the Executable version under a different - license You must make it absolutely clear that any terms which differ - from this License are offered by You alone, not by the Initial - Developer or any Contributor. You hereby agree to indemnify the - Initial Developer and every Contributor for any liability incurred by - the Initial Developer or such Contributor as a result of any such - terms You offer. - - 3.7. Larger Works. - You may create a Larger Work by combining Covered Code with other code - not governed by the terms of this License and distribute the Larger - Work as a single product. In such a case, You must make sure the - requirements of this License are fulfilled for the Covered Code. - -4. Inability to Comply Due to Statute or Regulation. - - If it is impossible for You to comply with any of the terms of this - License with respect to some or all of the Covered Code due to - statute, judicial order, or regulation then You must: (a) comply with - the terms of this License to the maximum extent possible; and (b) - describe the limitations and the code they affect. Such description - must be included in the LEGAL file described in Section 3.4 and must - be included with all distributions of the Source Code. Except to the - extent prohibited by statute or regulation, such description must be - sufficiently detailed for a recipient of ordinary skill to be able to - understand it. - -5. Application of this License. - - This License applies to code to which the Initial Developer has - attached the notice in Exhibit A and to related Covered Code. - -6. Versions of the License. - - 6.1. New Versions. - Netscape Communications Corporation ("Netscape") may publish revised - and/or new versions of the License from time to time. Each version - will be given a distinguishing version number. - - 6.2. Effect of New Versions. - Once Covered Code has been published under a particular version of the - License, You may always continue to use it under the terms of that - version. You may also choose to use such Covered Code under the terms - of any subsequent version of the License published by Netscape. No one - other than Netscape has the right to modify the terms applicable to - Covered Code created under this License. - - 6.3. Derivative Works. - If You create or use a modified version of this License (which you may - only do in order to apply it to code which is not already Covered Code - governed by this License), You must (a) rename Your license so that - the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape", - "MPL", "NPL" or any confusingly similar phrase do not appear in your - license (except to note that your license differs from this License) - and (b) otherwise make it clear that Your version of the license - contains terms which differ from the Mozilla Public License and - Netscape Public License. (Filling in the name of the Initial - Developer, Original Code or Contributor in the notice described in - Exhibit A shall not of themselves be deemed to be modifications of - this License.) - -7. DISCLAIMER OF WARRANTY. - - COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, - WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, - WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF - DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. - THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE - IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT, - YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE - COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER - OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF - ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER. - -8. TERMINATION. - - 8.1. This License and the rights granted hereunder will terminate - automatically if You fail to comply with terms herein and fail to cure - such breach within 30 days of becoming aware of the breach. All - sublicenses to the Covered Code which are properly granted shall - survive any termination of this License. Provisions which, by their - nature, must remain in effect beyond the termination of this License - shall survive. - - 8.2.

[Note: if you don't have a configure - script, skip down below to the Extremely detailed build - instructions.] - - The configure script attempts to automatically detect as much as - possible about your system. So, you should primarily just accept - its defaults by running: - - ./configure - - The configure script does accept a large number of options for - fine-tuning its behavior. See "./configure --help" for a complete - list. The most commonly used options are discussed here. - - --prefix=PREFIX - - This option specifies the directory under which the software - should be installed. By default configure will choose a - directory such as /usr/local. If you would like to install - cairo to some other location, pass the director to configure - with the --prefix option. For example: - - ./configure --prefix=/opt/cairo - - would install cairo into the /opt/cairo directory. You could - also choose a prefix directory within your home directory if - you don't have write access to any system-wide directory. - - After installing into a custom prefix, you will need to set - some environment variables to allow the software to be - found. Assuming the /opt/cairo prefix and assuming you are - using the bash shell, the following environment variables - should be set: - - PKG_CONFIG_PATH=/opt/cairo/lib/pkgconfig - LD_LIBRARY_PATH=/opt/cairo/lib - export PKG_CONFIG_PATH LD_LIBRARY_PATH - - (NOTE: On Mac OS X, at least, use DYLD_LIBRARY_PATH in place - of LD_LIBRARY_PATH above.) - - --enable-quartz - --enable-atsui - --enable-xcb - --enable-glitz - --enable-beos - --enable-os2 - --enable-directfb - - Some of cairo's backends are marked as experimental and will - not be built by default. If you would like to build and - experiment with these backends, you will need to pass one of - the above options to the configure script. You may need to - have certain libraries installed first as discussed in the - dependencies section of the README file. - - --disable-xlib - --disable-win32 - --disable-png - --disable-freetype - --disable-ps - --disable-pdf - --disable-svg - - Cairo's configure script detects the libraries needed to build - each stable backend, and when it finds them, enables each - backend. If you would like to override this detection and - disable a backend, (even when it would be possible to build - it), use one of the options above to disable the backend. - -2) Compile the package: - - This step is very simple. Just: - - make - - The Makefiles included with cairo are designed to work on as many - different systems as possible. - - When cairo is compiled, you can also run some automated tests of - cairo with: - - make check - - NOTE: Some versions of X servers will cause the -xlib tests to - report failures in make check even when cairo is working just - fine. If you see failures in nothing but -xlib tests, please - examine the corresponding -xlib-out.png images and compare them to - the -ref.png reference images (the -xlib-diff.png images might also - be useful). If the results seem "close enough" please do not report - a bug against cairo as the "failures" you are seeing are just due - to subtle variations in X server implementations. - -3) Install the package: - - The final step is to install the package with: - - make install - - If you are installing to a system-wide location you may need to - temporarily acquire root access in order to perform this - operation. A good way to do this is to use the sudo program: - - sudo make install - -Extremely detailed build instructions -------------------------------------- -So you want to build cairo but it didn't come with a configure -script. This is probably because you have checked out the latest -in-development code via git. If you need to be on the bleeding edge, -(for example, because you're wanting to develop some aspect of cairo -itself), then you're in the right place and should read on. - -However, if you don't need such a bleeding-edge version of cairo, then -you might prefer to start by building the latest stable cairo release: - - http://cairographics.org/releases - -or perhaps the latest (unstable) development snapshot: - - http://cairographics.org/snapshots - -There you'll find nicely packaged tar files that include a configure -script so you can go back the the simpler instructions above. - -But you're still reading, so you're someone that loves to -learn. Excellent! We hope you'll learn enough to make some excellent -contributions to cairo. Since you're not using a packaged tar file, -you're going to need some additional tools beyond just a C compiler in -order to compile cairo. Specifically, you need the following utilities: - - automake (1.8 or newer) - autoconf - libtool - -Hopefully your platform of choice has packages readily available so -that you can easily install things with your system's package -management tool, (such as "apt-get install automake" on Debian or "yum -install automake" on Fedora, etc.). Note that Mac OS X ships with it's -own utility called libtool which is not what you want, (the one you do -want goes by the name of glibtool). - -Once you have all of those packages installed, the next step is to run -the autogen.sh script. That can be as simple as: - - ./autogen.sh - -Or, if you're using Mac OS X, you'll have to let it know to use -glibtool by instead doing: - - LIBTOOLIZE=glibtoolize ./autogen.sh - -But before you run that command, note that the autogen.sh script -accepts all the same arguments as the configure script, (and in fact, -will generate the configure script and run it with the arguments you -provide). So go back up to step (1) above and see what additional -arguments you might want to pass, (such as prefix). Then continue with -the instructions, simply using ./autogen.sh in place of ./configure. - -Happy hacking! diff --git a/gfx/cairo/cairo/NEWS b/gfx/cairo/cairo/NEWS deleted file mode 100644 index 9be4062ca..000000000 --- a/gfx/cairo/cairo/NEWS +++ /dev/null @@ -1,5121 +0,0 @@ -Release 1.6.4 (2008-04-11 Carl Worth <cworth@cworth.org>) -========================================================= -The cairo community is wildly embarrassed to announce the 1.6.4 -release of the cairo graphics library. This release reverts the xlib -locking change introduced in 1.6.4, (and the application crashes that -it caused). The community would be glad to sack its current release -manager and is accepting applications for someone who could do the job -with more discipline. - -Revert 'add missing locking in cairo-xlib' ------------------------------------------- -This change was introduced in cairo 1.6.2, but also introduced a bug -which causes many cairo-xlib applications to crash, (with a -segmentation fault inside of XSetClipMask). Instead of attempting -another fix for the broken fix, the change in 1.6.2 has been -reverted. The original bug which the change was addressing has been -present since at least cairo 1.4, so it is not expected that leaving -this bug unfixed will cause any new problems for applications moving -from cairo 1.4 to cairo 1.6. - -At this point, the code of cairo 1.6.4 differs from cairo 1.6.0 only -in the fix for the PostScript-printer crashes. - -Tweak build to avoid linking with g++ -------------------------------------- -Cairo 1.6.4 avoids a quirk in automake that was causing the cairo -library to be linked with g++ and linked against libstdc++ even when -only C source files were compiled for the library. - -Release 1.6.2 (2008-04-11 Carl Worth <cworth@cworth.org>) -========================================================= -The cairo community is pleased (but somewhat sheepish) to announce the -1.6.2 release of the cairo graphics library. This is an update to -yesterday's 1.6.0 release with an important fix to prevent cairo's -PostScript output from crashing some printers. This release also -includes a locking fix for cairo's xlib backend to improve thread -safety. There are no changes beyond these two fixes. - -Fix for PostScript printer crash --------------------------------- -Adrian Johnson discovered that cairo 1.6.0 was being a bit hard on -PostScript printers, by changing the font matrix very frequently. This -causes some PostScript interpreters to allocate new font objects every -few glyphs, eventually exhausting available resources. The fix -involves leaving translational components of the font matrix as zero, -so that the PostScript interpreter sees an identical font matrix -repeatedly, and can more easily share internal font object resources. - -This fix has been tested to resolve the bugs posted here, (for both -Xerox and Dell printers): - - Printing some PDFs from evince is crashing our Xerox printer - http://bugs.freedesktop.org/show_bug.cgi?id=15348 - - Cairo-generated postscript blocks Dell 5100cn - http://bugs.freedesktop.org/show_bug.cgi?id=15445 - -Add missing locking in cairo-xlib ---------------------------------- -Chris Wilson noticed that cairo 1.6.0 was manipulating an internal -cache of GC object within cairo's Xlib backend without proper -locking. The missing locking could cause failures for multi-threaded -applications. He fixed this in 1.6.2 by adding the missing locks. - -Release 1.6.0 (2008-04-10 Carl Worth <cworth@cworth.org>) -========================================================= -The cairo community is quite pleased to announce the 1.6.0 release of -the cairo graphics library. This is a major update to cairo, with new -features and enhanced functionality which maintains compatibility for -applications written using cairo 1.4, 1.2, or 1.0. We recommend that -anybody using a previous version of cairo upgrade to cairo 1.6.0. - -The most significant new features in this release are dramatically -improved PDF and PostScript[*] output, support for arbitrary X server -visuals (including PseudoColor), a new Quartz backend, and and a new -"win32 printing" backend. See below for more details on these and -other new features. - -New dependency on external pixman library (Thanks, Søren!) ----------------------------------------------------------- -As of cairo 1.6, cairo now depends on the pixman library, for which -the latest release can be obtained alongside cairo: - - http://cairographics.org/releases/pixman-0.10.0.tar.gz - -This library provides all software rendering for cairo, (the -implementation of the image backend as well as any image fallbacks -required for other backends). This is the same code that was -previously included as part of cairo itself, but is now an external -library so that it can be shared by both cairo and by the X server, -(which is where the code originated). - -Improved PDF, PostScript, and SVG output (Thanks, Adrian!) ----------------------------------------------------------- -Users of the cairo-pdf, cairo-ps, and cairo-svg should see a dramatic -improvement from cairo 1.2/1.4 to 1.6. With this release there are now -almost no operations that will result in unnecessary rasterization in -the PDF and PostScript. Rasterized "image fallbacks" are restricted -only to minimal portions of the document where something is being -drawn with cairo that is beyond the native capabilities of the -document, (this is rare for PDF or SVG, but occurs when blending -translucent objects for PostScript). - -This means that the final output will be of higher quality, and will -also be much smaller, and therefore will print more quickly. The -machinery for doing analysis and minimal fallbacks also benefits the -win32-printing surface described below. - -In addition to doing less rasterization, the PostScript and PDF output -also has several other improvements to make the output more efficient -and more compatible with specifications. - -[*] Note: Just before this release, a bug has been reported that the -PostScript output from cairo can crash some printers, (so far the -following models have been reported as problematic Xerox Workcentre -7228 or 7328 and Dell 5100cn). We will implement a workaround as soon -as we can learn exactly what in cairo's output these printers object -to, (and we could use help from users that have access to misbehaving -printers). This bug is being tracked here: - - Printing some PDFs from evince is crashing our Xerox printer - http://bugs.freedesktop.org/show_bug.cgi?id=15348 - -New support for arbitrary X server visuals (Thanks, Keith and Behdad!) ----------------------------------------------------------------------- -As of cairo 1.6, cairo should now work with an arbitrary TrueColor or -8-bit PseudoColor X server visual. Previous versions of cairo did not -support these X servers and refused to draw anything. We're pleased to -announce that this limitation has been lifted and people stuck with -ancient display systems need no longer be stuck with ancient software -just because of cairo. - -New, supported Quartz backend for Mac OS X (Thanks, Brian and Vladimir!) ------------------------------------------------------------------------- -As of cairo 1.6, the cairo-quartz backend is now marked as "supported" -rather than "experimental" as in previous cairo releases. Its API now -has guarantees of API stability into future cairo releases, and its -output quality is comparable to other backends. There have been -significant improvements to cairo-quartz since 1.4. It now uses many -fewer image fallbacks, (meaning better performance), and has greatly -improved text rendering. - -New, "win32 printing" backend (Thanks, Adrian and Vladimir!) ------------------------------------------------------------- -A new win32-printing surface has been added with an interface very -similar to the original win32 surface, (both accept an HDC -parameter). But this new surface should only be called with a printing -DC, and will result in all drawing commands being stored into a -meta-surface and emitted after each page is complete. This allows -cairo to analyze the contents, (as it does with PDF, PostScript, and -SVG backends), and to do minimal image-based fallbacks as -necessary. The analysis keeps things as efficient as possible, while -the presence of fallbacks, (when necessary), ensure the consistent, -high-quality output expected from cairo. - -Robustness fixes (Thanks, Chris!) ---------------------------------- -There has been a tremendous number of improvements to cairo's -robustness. Areas that have been improved include: - - * Proper reporting of errors - - * Responding correctly to invalid input - - * Avoiding integer overflows - - * Avoiding memory leaks on error-recovery paths - - * Making reference counting thread safe - - * Exhaustive testing of memory allocation points - -Other fixes (Thanks, everybody!) --------------------------------- -Cairo's internal fixed-point representation has been changed from -16.16 to 24.8. This has a direct impact on applications as it allows -much larger objects to be drawn before internal limits in cairo make -the drawing not work. - -The CAIRO_EXTEND_PAD mode is now fully supported by surface -patterns. This mode allows applications to use cairo_rectangle and -cairo_fill to draw scaled images with high-quality bilinear filtering -for the internal of the image, but without any objectionably blurry -edges, (as would happen with the default EXTEND_NONE and cairo_paint). - -Rendering with CAIRO_ANTIALIAS_NONE has been fixed to be more -predictable, (previously image rendering and geometry rendering would -be slightly misaligned with respect to each other). - -The reference manual at http://cairographics.org/manual now documents -100% of the functions and types in cairo's public API. - -API additions -------------- -Several small features have been added to cairo with new API functions: - -cairo_format_stride_for_width - - Must be called to compute a properly aligned stride value before - calling cairo_image_surface_create_for_data. - -cairo_has_current_point - - Allows querying if there is a current point defined for the - current path. - -cairo_path_extents - - Allows querying for path extents, (independent of any fill or - stroke parameters). - -cairo_surface_copy_page -cairo_surface_show_page - - Allow beginning a new document page without requiring a cairo_t - object. - -cairo_ps_surface_restrict_to_level -cairo_ps_get_levels -cairo_ps_level_to_string -cairo_ps_surface_set_eps - - Allow controlling the Post PostScript level, (2 or 3), to - target, as well as to generate Encapsulated PostScript (EPS). - -cairo_quartz_font_face_create_for_cgfont - - Create a quartz-specific cairo_font_face_t from a CGFontRef. - -cairo_win32_font_face_create_for_logfontw_hfont - - Create a win32-specific cairo_font_face from a LOGFONTW and an - HFONT together. - -Thanks, Everyone! ------------------ -I've accounted for 32 distinct people with attributed code added to -cairo between 1.4.14 and 1.6.0, (their names are below).

It comes -just two days (and only one working day) after the 1.5.18 -snapshot. The quick snapshot is due to two embarrassing bugs (both -affecting cairo-xlib) that had been introduced in the 1.5.18 -snapshot. The fixes for these are described below along with a few -other fixes, (which hopefully aren't introducing new bugs this time). - -cairo-xlib ----------- -Revert fix from 1.5.18 to allow pattern expansion based on the filter -mode. This fix seemed so boring, (the use case it addresses is almost -never used in practice), that it didn't even get mentioned in the -1.5.18 release notes. However, the "fix" happened to break rendering -that is always used resulting in corrupt image rendering in mozilla, -evolution, and probably everything else that uses cairo. - -Fix to avoid BadMatch errors in cairo_surface_create_similar. These -were introduced, (inadvertently, of course), as part of the fix in -1.5.18 for creating similar surfaces without the Render -extension. Again, thanks to mozilla, (and Vladimir Vukicevic in -particular), for noticing our mistake. - -general -------- -Correctly handle an in-error surface in -cairo_surface_write_to_png. Previously this function would cause an -assertion failure if you gave it a finished surface. Now it cleanly -returns a CAIRO_STATUS_SURFACE_FINISHED result instead. - -Avoid potentially infinite wandering through memory inside -_cairo_hull_prev_valid. Thanks to Jonathan Watt for noticing this -problem: - - https://bugzilla.mozilla.org/show_bug.cgi?id=306649#c21 - -cairo-pdf ---------- -Fix generation of "soft" masks made by drawing to a similar surface -and then calling cairo_mask_surface() with it. - -cairo-svg ---------- -Fix for code that uses cairo_mask() on an intermediate surface which -is later passed to cairo_mask_surface(). - -Snapshot 1.5.18 (2008-04-05 Carl Worth <cworth@cworth.org>) -=========================================================== -This is the ninth snapshot in cairo's unstable 1.5 series. It comes -just 4 days after the 1.5.16 snapshot. We had hoped to not need -another snapshot before the final 1.6.0 release, but several critical -bugs were found and fixed in the last few days, so we thought it -important to let people test the fixes with this snapshot. See below -for details. - -documentation -------------- -The README now lists necessary dependencies. - -Various graphics state defaults are now documented, (source pattern is -opaque black, line width is 2.0, line join is miter, line cap is butt, -miter limit is 10.0, etc.). - -general -------- -Several cleanups have been made along many error-path returns, -(carefully propagating up the original error status values, cleaning -up memory leaks during error recovery, etc.). This is yet another in -Chris "ickle" Wilson's long series of error-handling cleanups during -the 1.5 series. - -Avoid undesired clipping when drawing scaled surface patterns with -bilinear filtering. - -cairo-pdf ---------- -Fix emission of 1-bit alpha masks in PDF output. - -Fix a bug that would cause glyphs to be misplaced along the Y axis: - - http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=%23474136 - - Originally, an issue about a crash, but later leading to the - misplaced glyphs issue being discovered. - -cairo-ps --------- -Fix misplaced glyphs in cairo's PostScript output. - - This issue occurs when consecutive glyphs are placed far - apart. This case is exercised by the new ft-show-glyphs-table test - case, which was originally inspired by the Debian bug #23474136 - mentioned above. - -Fix more misplaced glyphs in cairo's PostScript output: - - The issue here showed up under very particular circumstance, (when - converting a PDF file with a CFF font with CID Identity-H encoding - and using glyph 0, (defined by the CFF specification as .notdef) - as a space instead). More concretely, this problem appeared when - converting the UbuntuDesktop.pdf file mentioned in this bug - report: - - https://bugs.freedesktop.org/show_bug.cgi?id=15348#c3 - - As usual with arcane font-encoding-specific bugs like this, many - thanks to Adrian Johnson for his magical ability to dive into - specifications and emerge almost instantaneously with fixes. And - thanks to Sebastien Bacher for bringing the bug to our attention. - -cairo-xlib ----------- -Fix serious failure on X servers without the Render extension. - - Since the 1.5.14 snapshot (with support for PseudoColor visuals), - any application attempting to create a "similar" xlib surface would - fail on an X server without the Render extension. Thanks to - Frederic Crozat for pointing out that cairo's test suite was - entirely failing when run against Xvfb. - -Avoid crashing cairo-xlib applications for too-large glyphs - - Naively sending glyphs of any size to the X server will eventually - violate the X limit on maximum request sizes. We now properly - detect when a glyph would be too large and use existing fallbacks - to render the glyph rather than trying to send it to the X server. - -Enable the buggy_repeat workaround for Xorg servers < 1.4 - - We have determined that Xorg 1.3.0 (as packaged in Fedora 8 at - least) has a bug that can result in an X server crash when cairo - uses certain X Render repeat operations, (as exercised by cairo's - extend-reflect test). We avoid this crash by using fallbacks - whenever a repeating surface is needed for any Xorg server with a - version less than 1.4. This is slower, but should prevent the - crash. - - (Meanwhile, there appears to be a separate bug where some X - servers or specific X-server drivers will use random pixmap data - when asked to draw a repeating surface. The buggy_repeat - workaround would also avoid those problems, but we have not yet - characterized whether the new "version < 1.4" is a good - characterization of those problems or not.) - -cairo-quartz-font ------------------ -Implement cairo_font_extents for this backend. - -The cairo-quartz-font implementation added in the 1.5.14 snapshot was -entirely missing support for the cairo_font_extents function. Thanks to -Richard Hult for pointing out this obvious shortcoming, (and obvious -lack of coverage in our test suite): - - CGFont backend returns 0 font extents - https://bugs.freedesktop.org/show_bug.cgi?id=15319 - -Snapshot 1.5.16 (2008-04-01 Carl Worth <cworth@cworth.org>) -=========================================================== -This is the eighth snapshot in cairo's unstable 1.5 series. It comes -less than two weeks after the 1.5.14 snapshot and it really is a -legitimate snapshot, (in spite of sharing this date with that of many -bogus announcements). The major change in this snapshot is that the -cairo-quartz backend is now officially "supported", including new API -to construct a font face from a CGFontRef . Also several bug fixes -have been fixed in many backends. See below for details. - -general -------- -Cairo now depends on pixman 0.10.0 which was recently released. The -latest pixman release can always be found alongside cairo releases at: - - http://cairographics.org/releases - -Increase the precision of color stops for gradients. This fixes a -regression in gradient rendering that had been present since the -1.5.12 snapshot. - -paginated (all of ps, pdf, svg, and win32-printing) ---------------------------------------------------- -Fix assertion failure when some drawing elements are outside the page -boundaries, (this bug was noticed when using Inkscape to print a -drawing with landscape orientation to a portrait-oriented piece of -paper). - -cairo-ps --------- -Fix of bug causing incorrect glyph positioning. - -Fix handling of CAIRO_OPERATOR_SOURCE. - -cairo-pdf ---------- -More reduction of unnecessary digits of precision in PDF output. - -Fix handling of CAIRO_OPERATOR_SOURCE. - -cairo-svg ---------- -Fix bug in usage of libpng that was preventing cairo_mask from working -with the svg backend. - -Fix transformation of source pattern for cairo_stroke(). - -cairo-win32-printing --------------------- -Fix fallback resolution, (thanks again to inkscape users/developers -for helping us find this one). - -cairo-quartz ------------- -Mark the cairo-quartz backend as "supported" rather than -"experimental". This means the following: - - * The backend will now be built by default (if possible). - - * We are committing that the backend-specific API (as published in - cairo-quartz.h) are stable and will be supported in all future - cairo 1.x releases. - - * We are committing that the output quality of this backend - compares favorably with other cairo backends, (and that quality - is ensured by good results from the cairo test suite). - - * We recommend that distributions build and distribute this - backend when possible. - -Note that the cairo_quartz_image API (in cairo-quartz-image.h) is -still experimental, will not build by default, (pass ---enable-quartz-image to configure to build it), and may see API -changes before it is marked as "supported" in a future release. - -Put the CAIRO_FONT_TYPE_ATSUI name back into -cairo-deprecated.h. Without this, the cairo 1.5.14 snapshot broke all -builds for applications using the C++ cairomm bindings (and perhaps -others) which have the CAIRO_FONT_TYPE_ATSUI name in their header -files. This breakage happened even for applications not using -cairo-quartz at all. - - Note: Even though the CAIRO_FONT_TYPE_ATSUI name is provided to - avoid this build breakage, we still recommend that bindings and - applications move to the new, and more accurate, - CAIRO_FONT_TYPE_QUARTZ name. - -Replace the implementation of cairo-quartz-font to use CFFont instead -of ATSUI. The CGFont API is a better fit than ATSUI, and this new -implementation is also more correct than the old one as well. - -This also adds the following new API call: - - cairo_public cairo_font_face_t * - cairo_quartz_font_face_create_for_cgfont (CGFontRef font); - -The previous cairo_quartz_font_face_create_for_atsu_font_id function -continues to exist and is part of the supported API going -forward. (However, the old name of that same function, which was -cairo_atsui_font_face_create_for_atsu_font_id is officially -deprecated. Any source code using the old name should be updated to -use the new name.) - -Fix transformation of source pattern for cairo_stroke(). - -cairo-win32 ------------ -Avoid crash in create_similar is cairo_win32_surface_create fails. - -Snapshot 1.5.14 (2008-03-20 Carl Worth <cworth@cworth.org>) -=========================================================== -This is the seventh snapshot in cairo's unstable 1.5 series. It comes -3 weeks after the 1.5.12 snapshot. This snapshot includes support for -arbitrary X server visuals, (including PseudoColor), which was the -final remaining cairo-specific item on the cairo 1.6 roadmap. It also -includes a huge number of improvements to the cairo-quartz backend. So -this is effectively a cairo 1.6 release candidate. We expect very few -changes from now until 1.6 and only for specific bug fixes. - -API Change ----------- -Rename ATSUI font backend to Quartz font backend. This affects the -following usage: - - --enable-atsui -> --enable-quartz-font - CAIRO_HAS_ATSUI_FONT -> CAIRO_HAS_QUARTZ_FONT - CAIRO_FONT_TYPE_ATSUI -> CAIRO_FONT_TYPE_QUARTZ - - cairo_atsui_font_face_create_for_atsu_font_id -> - cairo_quartz_font_font_create_for_atsu_font_id - -This API change is justified by the cairo-quartz backend still be -marked as "experimental" rather than "supported", (though this is one -step toward making the change to "supported" before 1.6). Cairo will -still provide ABI compatibility with the old symbol name, however. - -paginated (all of ps, pdf, svg, and win32-printing) ---------------------------------------------------- -Optimize by not analyzing an image surface for transparency more than -once, (previously all images were analyzed twice). - -cairo-ps and cairo-pdf ----------------------- -Avoiding emitting a matrix into the stroke output when unnecessary, -(making output size more efficient). - -Reduce rounding error of path shapes by factoring large scale factors -out of the path matrix, (ensuring that a fixed-number of printed -digits for path coordinates contains as much information as possible). - -Reduce excess digits for text position coordinates. This makes the -output file size much smaller without making the result any less -correct. - -cairo-ps --------- -Eliminate bug causing extraneous text repetition on Linux PostScript -output in some cases. - - See: Mozilla Bug 419917 – Printed page contents are reflected - inside bordered tables (Linux-only) - - https://bugzilla.mozilla.org/show_bug.cgi?id=419917 - -Optimize output when EXTEND_PAD is used. - -cairo-pdf ---------- -Fix to not use fill-stroke operator with transparent fill, (else PDF -output doesn't match the cairo-defined correct result). See: - - https://bugs.launchpad.net/inkscape/+bug/202096 - -cairo-svg ---------- -Fix stroke of path with a non-solid-color source pattern: - - http://bugs.freedesktop.org/show_bug.cgi?id=14556 - -cairo-quartz ------------- -Fix text rendering with gradient or image source pattern. - -Handling antialiasing correctly for cairo_stroke(), cairo_clip(), and -cairo_show_text()/cairo_show_glyphs(). - -Correctly handle gradients with non-identity transformations: - - Fixes http://bugs.freedesktop.org/show_bug.cgi?id=14248 - -Add native implementation of REPEAT and REFLECT extend modes for -gradients. - -Fix implementation for the "unbounded" operators, (CAIRO_OPERATOR_OUT, -_IN, _DEST_IN, and _DEST_ATOP). - -Correctly handle endiannees in multi-architecture compiles on Mac OS -X. - -Avoid behavior which would cause Core Graphics to print warnings to -the console in some cases. - -cairo-win32 ------------ -Fix handling of miter limit. - -cairo-win32-printing --------------------- -Fix to not use a 1bpp temporary surface in some cases while printing, -(so grayscale data is preserved rather than just becoming black and -white). - -cairo-xlib ----------- -Add support for rendering to arbitrary TrueColor X server -visuals. This fixes at least the following bugs: - - cairo doesn't support 8-bit truecolor visuals - https://bugs.freedesktop.org/show_bug.cgi?id=7735 - - cairo doesn't support 655 xlib format - https://bugs.freedesktop.org/show_bug.cgi?id=9719 - -Add support for rendering to 8-bit PseudoColor X server visuals. This -fixes the following bug: - - Cairo doesn't support 8-bit pseudocolor visuals - https://bugs.freedesktop.org/show_bug.cgi?id=4945 - -Snapshot 1.5.12 (2008-02-28 Carl Worth <cworth@cworth.org>) -=========================================================== -This is the sixth snapshot in cairo's unstable 1.5 series. It comes 1 -week after the 1.5.10 snapshot. This snapshot includes the -long-awaited change from 16.16 to 24.8 fixed-point values, (see below -for why you should care). It also includes several backend-specific -bug fixes. - -24.8 fixed-point format ------------------------ -Cairo has always converted path coordinates to a fixed-point -representation very early in its processing. Historically, this has -been a 32-bit representation with 16 bits of integer for the -device-pixel grid and 16 bits of sub-pixel positioning. The choice of -16 bits for the integer coordinate space was based on the 16-bit limit -for X Window drawables. - -This 16-bit limit has proven problematic for many applications. It's -an especially vexing problem when targeting non-X backends that don't -have any 16-bit restriction. But even when targeting cairo-xlib, it's -often desirable to draw a large shape, (say a background rectangle), -that extends beyond the surface bounds and expect it to fill the -surface completely, (rather than overflowing and triggering random -behavior). - -Meanwhile, nobody has ever really needed 16 bits of sub-pixel -precision. - -With this snapshot, the fixed-point system is still in place and is -still using a 32-bit representation, (future versions of cairo might -move entirely to floating-point when targeting PDF output for -example). But the representation now provides 24 bits of pixel -addressing and only 8 bits of sub-pixel positioning. This should give -a much less stifling space to many applications. - -However, the underlying pixman library still has 16-bit limitations in -many places, (it has its roots in the X server as well). Until those -are also fixed, applications targeting cairo image surfaces, or -hitting software fallbacks when targeting other surfaces will still -encounter problems with device-space values needing more than 16 -integer bits. - -generic fixes -------------- -Add a few tests to the test suite to increase coverage. - -Cleanup a few error-handling paths, (propagate error correctly). - -cairo-ft --------- -Fix handling of font sizes smaller than 1 device pixel. - -cairo-pdf ---------- -Fix to properly save/restore clip when analyzing meta-surface -patterns, (fixing a couple of test-suite failures). - -Implement native support for CAIRO_OPERATOR_SOURCE when the source -pattern is opaque. - -Emit rectangles as PDF rectangles ("re" operator) rather than as -general paths. - -cairo-ps --------- -Fix to work properly with the 16.16->24.8 change. - -cairo-svg ---------- -Fix CAIRO_EXTEND_REFLECT by using an image fallback, (there's no -direct SVG support for reflected patterns). - -Fix the use of alpha-only masks, (such as CAIRO_FORMAT_A8). - -cairo-quartz ------------- -Add new API for efficiently using image data as a source: - - cairo_surface_t * - cairo_quartz_image_surface_create (cairo_surface_t *image_surface); - - cairo_surface_t * - cairo_quartz_image_surface_get_image (cairo_surface_t *surface); - -For full documentation, see: - - http://cairographics.org/manual/cairo-Quartz-Surfaces.html#cairo-quartz-image-surface-create - -Several fixes for cairo_mask(). - -cairo-atsui ------------ -Change default from from Monaco to Helvetica to be more consistent -with other font backends. - -Snapshot 1.5.10 (2008-02-20 Carl Worth <cworth@cworth.org>) -=========================================================== -This is the fifth snapshot in cairo's unstable 1.5 series. It comes 3 -weeks after the 1.5.8 snapshot. This snapshot adds one new API -function, (cairo_has_current_point), and the usual mix of -improvements, (more efficient PostScript/PDF output, optimized -stroking), and fixes (more robust error-handling, etc.). See below for -details. - -New API -------- -Add a new function to query if there is a current point: - - cairo_bool_t - cairo_has_current_point (cairo_t *cr); - -There is no current point immediately after cairo_create(), nor after -cairo_new_path() or cairo_new_sub_path(). There is a current point -after any of the path-creation functions, (cairo_move_to, -cairo_line_to, cairo_curve_to, etc.). - -With this new function, we also revert the change of the return type -of cairo_get_current_point from cairo 1.5.8, (it's now a void function -again). - -Optimizations -------------- -Optimize stroking code to avoid repeated calculation of redundant -values, (particularly significant for very large, offscreen paths). - -General fixes -------------- -Patch a few more potential buffer overruns, (due to integer -overflow). - -Many fixes and improvements to cairo's error-handling, (ensure that -correct error values are returned, clean up memory leaks on -error-handling paths, etc.). - -Fix a potential infinite loop when stroking a spline with a pen that -has been transformed to a line segment. - -Remove treating NULL as a synonym for a valid cairo_font_options_t* -with default values, (a change that had been introduced as of cairo -1.5.8). - -Remove the altered handling of tolerance and fallback-resolution that -had been introduced as of cairo 1.5.4. - -cairo-xlib ----------- -Pass the original Drawable, (as opposed to the root window), to -XCreatePixmap when creating a similar surface. This gives the X server -more information so that it can be clever and efficient. - -cairo-pdf ---------- -Fix the rendering of repeating and reflecting patterns. - -Ensure miter limit is always >= 1, (smaller limits are not meaningful, -but they can cause some PDF viewers to fail to display pages). - -Generate more efficient output when the same path is used for both -fill and stroke. - -cairo-ps --------- -Start sharing much of the cairo-pdf code rather than implementing very -similar code in cairo-ps. - -Implement native support for repeating and reflecting linear -gradients. - -Implement reflected surface patterns. - -Ensure miter limit is always >= 1, (smaller limits are not meaningful, -but they can cause some PostScript viewers to crash). - -Generate PostScript that will perform more efficiently and use less -memory on printers, (use currentfile instead of a giant string array -for image data, and avoid using PostScript patterns for paint() and -fill() when possible). - -cairo-svg ---------- -Avoid unnecessary rasterization when copying a "similar" surface to -another svg surface, (allow the SOURCE operator to be implemented with -all-vector operations if there are no underlying objects). - -cairo-atsui ------------ -Eliminate infinite loop when attempting to render an empty string. - -Snapshot 1.5.8 (2008-01-30 Carl Worth <cworth@cworth.org>) -========================================================== -This is the fourth snapshot in cairo's unstable 1.5 series. It comes 2 -weeks after the 1.5.6 snapshot. It adds a few new API functions. Most -notably all callers of cairo_image_surface_create_for_data should now -be calling cairo_format_stride_for_width to compute a legal stride -value. See below for more details. - -New API in cairo 1.5.8 ----------------------- -We've added a new function that should be called to compute a legal -stride value before allocating data to be used with -cairo_image_surface_create_for_data: - - int - cairo_format_stride_for_width (cairo_format_t format, - int width); - -We've also added a new cairo_path_extents function that can be used to -compute a bounding box for geometry such as a single line segment, -(contrast with cairo_path_extents and cairo_stroke_extents): - - void - cairo_path_extents (cairo_t *cr, - double *x1, double *y1, - double *x2, double *y2); - -And finally, we've added a function to allow for querying the -XRenderPictFormat of a cairo-xlib surface: - - XRenderPictFormat * - cairo_xlib_surface_get_xrender_format (cairo_surface_t *surface); - -API changes ------------ -Fix return types of cairo_surface_show_page and -cairo_surface_copy_page. This is an API change to functions that are -new in the 1.5 series, so not an API break compared to any stable -cairo release, (1.0.x, 1.2.x, 1.4.x). - -Change the return type of cairo_get_current_point() from void to -cairo_status_t. This allows the caller to receive a -CAIRO_STATUS_NO_CURRENT_POINT value to distinguish the a current point -at the origin from no current point existing. - -Performance improvement ------------------------ -Improve performance of clipping by using an optimized code path -internally, (with the ADD operator instead of IN). - -General bug fixes ------------------ -Fix various cairo_*_extents functions to initialize the return-value -variables even in the case of a cairo_t in error. - -Treat NULL as a legitimate value for cairo_font_options_t*. [NOTE: -On discussion afterwards, we decided against this change so it has -been removed as of cairo 1.5.10.] - -Fix rendering with CAIRO_ANTIALIAS_NONE to be more predictable, (that -is, to avoid seams appearing when geometry and imagery share an -identical edge). Portions of this fix are in the pixman library and -will appear in a future release of that library. - -Avoid triggering an error for a font size of 0. - -Miscellaneous changes ---------------------- -Require pixman >= 0.9.6. - -There has been a tremendous amount improvement to cairo's -documentation. We're delighted that 100% of the public API has at -least some documentation in the API reference manual. Many thanks to -Behdad Esfahbod and Nis Martensen for leading this effort. - -cairo-pdf and cairo-ps ----------------------- -Eliminate failure when a Type 1 font is embedded with an explicit -glyph 0. - -cairo-pdf ---------- -Implement a more correct and more efficient approach for patterns with -an extend mode of CAIRO_EXTEND_REFLECT. - -cairo-ps --------- -Fix image masks to properly pack and pad mask bits. - -cairo-quartz ------------- -Take care to only use DrawTiledImage for integer-aligned images, (and -use slower paths to get the correct result in other cases). - -cairo-win32 ------------ -Fix for older versions of mingw. - -Improve the handling of the clipping with the win32 and win32-printing -surfaces. - -Fix rendering of non black/white text. - -Snapshot 1.5.6 (2008-01-15 Carl Worth <cworth@cworth.org>) -========================================================== -This is the third snapshot in cairo's unstable 1.5 series. It comes -about 6 weeks after the 1.5.4 snapshot. The only API addition compared -to 1.5.4 is very minor, (a new value CAIRO_STATUS_TEMP_FILE_ERROR). -The remainder of the changes are the usual accumulation of bug fixes -and improvements. See below for details. - -General bug fixes ------------------ -Fix handling of fonts that contain a mixture of outline and bitmapped -glyphs. There was a change in this handling in 1.5.4 that improved -some cases and also regressed other cases. Now, all cases should be -handled quite well. - -Fix alignment issues that were causing SIGBUS failures on SPARC. - -Fix a regression (which first appeared in 1.5.2) where stroking under -a large scale would sometimes incorrectly replace a miter join with a -bevel join. (Thanks to Keith Packard.) - -Fix reporting of zero-sized extents to be {0,0} rather than -{INT_MAX,INT_MIN}. This avoids several integer overflow and -allocations of massive regions in some cases. - -Fix failures of gradients with no stops, (quartz, ps, and pdf). - -Fix handling of Type 1 fonts on Windows platforms. - -Fix handling of Type 1 fonts with no specific family name in the font -itself, (generate a CairoFont-x-y name). - -Handle NULL string values in cairo_show_text, cairo_show_glyphs, and -friends. - -Many robustness improvements along error-handling paths, (thanks as -always, to Chris "ickle" Wilson). - -Various other minor fixes. - -Paginated backends (PDF/PostScript/win32-printing) --------------------------------------------------- -Avoid unnecessary rasterization when using a paginated surface as a -source, (such as drawing from one pdf surface to another). - -Fix replaying of paginated surface with more than one level of push/pop -group. - -cairo-xlib ----------- -Fix xlib backend to not consider recent X server release as having a -buggy repeat implementation in the Render extension. - -cairo-pdf ---------- -Fix PDF output to avoid triggering very slow rendering in PDF viewers, -(avoid starting and stopping the content stream for each pattern -emission). - -Support CAIRO_OPERATOR_SOURCE in cases where there is nothing below -the object being drawn. - -Fix to avoid seams appearing between multiple fallback regions. - -cairo-ps (PostScript) ---------------------- -Use correct bounding box in Type 3 fonts. - -Fix several bugs in cairo's PostScript output. These include making -the PostScript output more compatible with recent versions of -ghostscript that are more strict about Type 3 fonts, for -example. - -Fix for win32 to not attempt to create temporary files in the root -directory, (where the user may not have write permission). - -Avoid generating Level 3 PostScript if Level 2 is sufficient. Also, -add code in output documents to alert the user if Level 3 PostScript -is handed to a device that cannot handle PostScript beyond Level -2. - -cairo-directfb --------------- -Various performance optimizations. - -Fixed support for small surfaces (less than 8x8). - -Provide support for environment variables CAIRO_DIRECTFB_NO_ACCEL to -disable acceleration and CAIRO_DIRECTFB_ARGB_FONT to enable ARGB fonts -instead of A8. - -cairo-os2 ---------- -Allow OS/2 APIs instead of C library allocation functions. - -Snapshot 1.5.4 (2007-12-05 Carl Worth <cworth@cworth.org>) -========================================================== -This is the second snapshot in cairo's unstable 1.5 series. It comes -just over 1 month after the 1.5.2 snapshot. There are no API changes -or additions in 1.5.4 compared to 1.5.2, but there are several bug -fixes, and some optimizations. Most of these apply to particular -backends. See below for details. - -General improvements --------------------- -Use less memory for spline approximation calculations. - -Change how the tolerance value is interpreted with regard to -fallback-resolution. [Note: On further discussion, we decided against -this change for now. It is removed as of cairo 1.5.10.] - -Fix precision of floating-point values in vector-output backends to -avoid rounding errors with very small numbers. - -Xlib improvements ------------------ -Fix bug in glyph rendering with xlib, (due to everything being clipped -out). This was a regression in the 1.5.2 snapshot that was visible in -the GIMP, for example. See: - - cairo 1.5.2 causes font problems in GIMP 2.4 status bar and evolution 2.12.1 - https://bugs.freedesktop.org/show_bug.cgi?id=13084 - -PostScript improvements ------------------------ -Fix bug leading to invalid PostScript files when rendering -text, (need "0 0 xyshow" instead of "0 xyshow"). - -Fix many issues with Type 3 fonts, including making the resulting text -extractable. - -Quartz improvements -------------------- -Fix font metrics height value for ATSUI, (helps webkit on GTK+ OS X -layout nicely). - -Fix gradients. - -Fix EXTEND_NONE mode for patterns. - -Fix cairo_quartz_surface_create to properly clear the new surface -in cairo_quartz_surface_create. - -Fix to correctly handle 0x0 sized surfaces. - -Optimize drawing of ExtendMode::REPEAT patterns for OS X 10.5. - -Snapshot 1.5.2 (2007-10-30 Carl Worth <cworth@cworth.org>) -========================================================== -This is the first snapshot in cairo's unstable 1.5 series. It comes 4 -months after the 1.4.10 release. This snapshot includes significant -improvements to PDF and PostScript output, which is one of the things -in which we're most interested in getting feedback. There are a couple -of minor API additions, and several optimizations, (primarily in the -"print/vector" backends). And there are dozens of bug fixes and -robustness improvements. - -New dependency on external pixman library ------------------------------------------ -A significant change in this snapshot compared to all previous cairo -releases is that cairo now depends on an external "pixman" library for -its software rendering. Previously this same code was compiled -internally as part of cairo, but now the code is separate so that both -cairo and the X server can now share common code, (thanks very much to -Søren Sandmann for his work on separating pixman and maintaining it). - -So users will need to acquire and build pixman before being able to -build cairo. The current release is 0.9.6 and can be obtained from -here: - - http://cairographics.org/releases/pixman-0.9.6.tar.gz - - which can be verified with: - - http://cairographics.org/releases/pixman-0.9.6.tar.gz.sha1 - 66f01a682c64403a3d7a855ba5aa609ed93bcb9e pixman-0.9.6.tar.gz - - http://cairographics.org/releases/pixman-0.9.6.tar.gz.sha1.asc - (signed by Carl Worth) - -Major PDF/PostScript improvements ---------------------------------- -Adrian Johnson has done some long-awaited work to make cairo's PDF and -PostScript output more interesting than ever before. First, many -operations that previously triggered image fallbacks will now be -rendered as native vectors. These operations include: - - PDF: cairo_push_group, cairo_surface_create_similar, - cairo_mask, A8/A1 surface sources, repeating/reflecting linear - gradients. - - PostScript: cairo_push_group, cairo_surface_create_similar, - gradients, bilevel alpha masks, (for example, all values either 0 or - 255 for an A8 mask). - -Not only that, but when an image fallback is required, it will now be -limited to only the necessary region. For example, a tiny translucent -image overlaying a small portion of text would previously caused an -entire PostScript page to be rendered as a giant image. Now, the -majority of that page will be nice text, and there will only be a tiny -image in the output. - -Additionally, the PostScript output now carefully encodes text so that -if it is subsequently converted to PDF, the text will be -selectable. - -This is very exciting progress, and we're hoping to hear from users -during the 1.5 series about how things have improved, (for example, -inkscape users doing cairo-based PDF export: please let us know how -things look). And feel free to pass your thanks along to Adrian for his excellent work. - -NOTE: This much improved PDF output makes more sophisticated use of -functionality in the PDF specification. This means that cairo's output -will sometimes expose bugs in some free software PDF viewers, (evince, -poppler, and xpdf, for example), that are not yet ready for such PDF -files. We're working with the poppler maintainers to get these bugs -fixed as quickly as possible. In the meantime, please double-check -with other PDF viewers if cairo-generated PDF files are not being -rendered correctly. It may be due to a bug in the viewer rather than -in the PDF file that cairo has created. - -Robustness improvements ------------------------ -Chris Wilson has made the largest contribution by far to cairo 1.5.2, -(in number of commits). His more than 150 commits include a huge -number of fixes to increase cairo's robustness. These fixes make cairo -more robust against invalid and degenerate input, (NaN, empty path, -etc.), against size-0 malloc calls, against memory leaks on -error-recovery paths, and against other failures during error -handling. He also implemented atomic operations to cairo, and used -them to fix cairo's previously non-thread-safe reference counting, -again improving robustness. - -Chris has put a tremendous amount of time and effort into writing -analysis tools for this work, and in running those tools and fixing -the problems they report. We're very grateful for this work, and hope -that all cairo users appreciate the more robust implementation that -results from it. - -This work is largely thankless, so it might make sense to notice -sometime that cairo has been running quite smoothly for you, and when -you do, send a quick "thank you" off to Chris Wilson, since it -is all definitely running smoother thanks to his work. - -New API -------- -There are no major additions to cairo's core API. The only new, -generic functions are: - - void - cairo_surface_copy_page (cairo_surface_t *surface); - - void - cairo_surface_show_page (cairo_surface_t *surface); - -which can now be used much more conveniently than the existing -cairo_copy_page and cairo_show_page functions in some -situations. These functions act identically, but require only a -cairo_surface_t* and not a cairo_t*. - -All other API additions are specific to particular backends. - -New cairo-win32 API (new font face function and "win32 printing" surface) -------------------------------------------------------------------------- -There is a new function for creating a win32 font face for both a -logfontw and an hfont together. This complements the existing -functions for creating a font face from one or the other: - - cairo_font_face_t * - cairo_win32_font_face_create_for_logfontw_hfont (LOGFONTW *logfont, - HFONT font); - -There is also a new "win32 printing" surface: - - cairo_surface_t * - cairo_win32_printing_surface_create (HDC hdc); - -This interface looks identical to the original -cairo_win32_surface_create, (both accept and HDC), but the behavior of -this new surface is very different. It should only be called with a -printing DC, and will result in all drawing commands being stored into -a meta-surface and emitted after each page is complete, with analysis -to do as minimal image-based fallbacks as necessary. The behavior and -implementation shares much with the PDF and PostScript backends. - -New cairo-ps API (EPS and PostScript level control) ---------------------------------------------------- -An often requested feature has been the ability to generate -Encapsulated PostScript (EPS) with cairo. We have that now with the -following very simple API. Just do cairo_ps_surface_create as usual -then call this function with a true value: - - void - cairo_ps_surface_set_eps (cairo_surface_t *surface, - cairo_bool_t eps); - -[NOTE: As always with snapshots, it's possible---though not very -likely---that the API could still be modified before a final -release. For example, this is the first public cairo function that -accepts a Boolean parameter. I'm generally opposed to Boolean -parameters, but this is probably the one case where I'm willing to -accept one, (namely a "set" function that accepts a single Boolean).] - -Also, it is now possible to control what PostScript level to target, -(either level 2 or level 3), with the following new API: - - typedef enum _cairo_ps_level { - CAIRO_PS_LEVEL_2, - CAIRO_PS_LEVEL_3 - } cairo_ps_level_t; - - void - cairo_ps_surface_restrict_to_level (cairo_surface_t *surface, - cairo_ps_level_t level); - - void - cairo_ps_get_levels (cairo_ps_level_t const **levels, - int *num_levels); - - const char * - cairo_ps_level_to_string (cairo_ps_level_t level); - -Improvement for cairo-quartz ----------------------------- -Brian Ewins had contributed several improvements to cairo-quartz. These -include an implementation of EXTEND_NONE for linear and radial -gradients, (so this extend mode will no longer trigger image fallbacks -for these gradients), as well as native surface-mask clipping, (only -on OS X 10.4+ where the CGContextClipToMask function is available). - -He also fixed a semantic mismatch between cairo and quartz for dashing -with an odd number of entries in the dash array. - -We're grateful for Brian since not many quartz-specific improvements -to cairo would be happening without him. - -Optimizations -------------- -Optimize SVG output for when the same path is both filled and stroked, -and avoid unnecessary identity matrix in SVG output. (Emmanuel Pacaud). - -Optimize PS output to take less space (Ken Herron). - -Make PS output more compliant with DSC recommendations (avoid initclip -and copy_page) (Adrian Johnson). - -Make PDF output more compact (Adrian Johnson). - -Release glyph surfaces after uploading them to the X server, (should -save some memory for many xlib-using cairo application). (Behdad -Esfahbod). - -Optimize cairo-win32 to use fewer GDI objects (Vladimir Vukicevic). - -win32-printing: Avoid falling back to images when alpha == 255 -everywhere. (Adrian Johnson). - -win32-printing: Avoid falling back for cairo_push_group and -cairo_surface_create_similar. (Adrian Johnson) - -Bug fixes ---------- -Avoid potential integer overflows when allocating large buffers -(Vladimir Vukicevic). - -Preparations to allow the 16.16 fixed-point format to change to -24.8 (Vladimir Vukicevic). - -Fix bugs for unsupported X server visuals (rgb565, rgb555, bgr888, and -abgr8888). (Carl Worth and Vladimir Vukicevic) - -Fix bugs in PDF gradients (Adrian Johnson). - -Fix cairo-xlib to build without requiring Xrender header -files (Behdad Esfahbod). - -Make cairo more resilient in the case of glyphs not being available in -the current font. (Behdad Esfahbod) - -Prevent crashes when both atsui and ft font backends are compiled in -(Brian Ewins). - -Make font subsetting code more robust against fonts that don't include -optional tables (Adrian Johnson). - -Fix CFF subsetting bug, (which manifested by generating PDF files that -Apple's Preview viewer could not read) (Adrian Johnson). - -Fixed error handling for quartz and ATSUI backends (Brian Ewins). - -Avoid rounding problems by pre-transforming to avoid integer-only -restrictions on transformation in GDI (Adrian Johnson). - -Fixed an obscure bug (#7245) computing extents for some stroked -paths (Carl Worth). - -Fix crashes due to extreme transformation of the pen, (seems to show -up in many .swf files for some reason) (Carl Worth). - -Release 1.4.10 (2007-06-27 Carl Worth <cworth@cworth.org>) -========================================================== -This is the fifth update in cairo's stable 1.4 series. It comes -roughly three weeks after the 1.4.8 release. The most significant -change in this release is a fix to avoid an X error in certain cases, -(that were causing OpenOffice.org to crash in Fedora). There is also a -semantic change to include child window contents when using an xlib -surface as a source, an optimization when drawing many rectangles, and -several minor fixes. - -Eliminate X errors that were killing OO.o (Chris Wilson) --------------------------------------------------------- -Cairo is fixed to avoid the X errors propagated when cleaning up -Render Pictures after the application had already destroyed the -Drawable they reference. (It would be nice if the X server wouldn't -complain that some cleanup work is already done, but there you have -it.) This fixes the bug causing OpenOffice.org to crash as described -here: - - XError on right click menus in OOo. - https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=243811 - -Use IncludeInferiors when using xlib surface as a source (Ryan Lortie) ----------------------------------------------------------------------- -When an xlib surface is used as the source of a draw operation the -contents of child windows are now included in the source data. The -semantics of drawing to xlib surfaces are unchanged (ie: draws are -still clipped by child windows overlapping the destination window). - -Optimize drawing of many rectangles (Vladimir Vukicevic) --------------------------------------------------------- -Avoid O(N*N) loop when filling many axis-aligned rectangles, (either -many rectangles as separate sub-paths or due to dashing). - -Miscellaneous fixes -------------------- -Fix cairo-perf on Solaris by linking to librt. (Behdad Esfahbod) - -Fix make check for systems that require executable files to have a -particular extension. (Behdad Esfahbod) - -Eliminate some warnings in cairo-quartz. (Brian Ewins) - -Fix build-breaking typo for cairo-directfb. (Chris Wilson) - -Release 1.4.8 (2007-06-07 Carl Worth <cworth@cworth.org>) -========================================================= -This is the fourth update in cairo's stable 1.4 series. It comes just -over five weeks after the 1.4.6 release. This release includes a -thread-safe surface-cache for solid patterns which significantly -improves text rendering with the xlib backend. Also, dozens of error -paths in cairo have been fixed thanks to extensive fault-injection -testing by Chris Wilson. - -Surface cache for solid patterns --------------------------------- -Originally written by Jorn Baayen, the introduction of a small cache -for surfaces created for solid patterns improves performance -dramatically. For example, this reduces the volume of X requests -during text rendering to the same level as Xft. - -This cache first made its appearance in a 1.3.x snapshot, but was -removed before appearing in any previous major release due to -complications with multi-threaded programs. For example, programs like -evince that would carefully restrict usage of cairo-xlib to a single -thread were unpleasantly surprised to find that using cairo-image in a -separate thread could trigger X requests. - -Behdad Esfahbod designed a fix which was implemented by Chris -Wilson. Now, the necessary X requests are queued up until the next -time the application directly operates on an xlib surface. - -Improved error handling paths ------------------------------- -Chris Wilson continued the excellent work he started in cairo 1.4.4 to -make cairo much more robust against out-of-memory and other errors. He -applied his memory allocation fault injection cairo's main test suite, -(previously he had applied it to cairo's performance suite). - -Chris's testing found dozens of bugs which he fixed. Many of these -bugs had perhaps never been hit by any users. But at least one was -hit by the gnome-about program which resulted in dozens of duplicated -bug reports against that program: - - http://bugzilla.gnome.org/show_bug.cgi?id=431990 - -We were very pleasantly surprised to see this bug get fixed as a -side-effect of Chris's work. Well done, Chris! - -Other fixes ------------ -Cleanup of mutex declarations (Behdad Esfahbod) - -Remove unnecessary clip region from SVG output (Emmanuel Pacaud) - -Remove Xsun from the buggy_repeat blacklist (Elaine Xiong) - -ATSUI: Fix glyph measurement: faster and more correct (Brian Ewins) - -Quartz: fixed 'extend' behaviour for patterns, improved pattern performance, -and a few smaller correctness fixes. (Brian Ewins, Vladimir Vukicevic) - -Release 1.4.6 (2007-05-01 Carl Worth <cworth@cworth.org>) -========================================================= -This is the third update in cairo's stable 1.4 series. It comes a -little less than three weeks since the 1.4.4 release. This release -fixes the broken mutex initialization that made cairo 1.4.4 unusable -on win32, OS/2, and BeOS systems. This release also adds significant -improvements to cairo's PDF backend, (native gradients!), and a couple -of performance optimizations, (one of which is very significant for -users of the xlib backend). See below for more details. - -Repaired mutex initialization ------------------------------ -We apologize that cairo 1.4.4 did little more than crash on many -platforms which are less-frequently used by the most regular cairo -maintainers, (win32, OS/2, and BeOS). The mutex initialization -problems that caused those crashes should be fixed now. And to avoid -similar problems in the future, we've now started posting pre-release -snapshots to get better testing, (subscribe to cairo@cairographics.org -if you're interested in getting notified of those and testing them). - -PDF Improvements ----------------- -Thanks to Adrian Johnson, (cairo PDF hacker extraordinaire), we have -several improvements to cairo's PDF backend to announce: - -Native gradients: - - As of cairo 1.4.6, cairo will now generate native PDF gradients in - many cases, (previously, the presence of a gradient on any page - would force rasterized output for that page). Currently, only - gradients with extend types of PAD (the default) or NONE will - generate native PDF gradients---others will still trigger - rasterization, (but look for support for other extend modes in a - future release). Many thanks to Miklós Erdélyi as well, who did the - initial work for this support. - -Better compatibility with PDF viewers: - - The PDF output from cairo should now be displayed correctly by a - wider range of PDF viewers. Adrian tested cairo's PDF output against - many PDF viewers, identified a common bug in many of those viewers - (ignoring the CTM matrix in some cases), and modified cairo's output - to avoid triggering that bugs (pre-transforming coordinates and - using an identity matrix). - -Better OpenType/CFF subsetting: - - Cairo will now embed CFF and TrueType fonts as CID fonts. - -Performance optimizations -------------------------- -Faster cairo_paint_with_alpha: - - The cairo_paint_with_alpha call is used to apply a uniform alpha - mask to a pattern. For example, it can be used to gradually fade an - image out or in. Jeff Muizelaar fixed some missing/broken - optimizations within the implementation of this function resulting - in cairo_paint_with_alpha being up to 4 times faster when using - cairo's image backend. - -Optimize rendering of "off-screen" geometry: - - Something that applications often do is to ask cairo to render - things that are either partially or wholly outside the current clip - region. Since 1.4.0 the image backend has been fixed to not waste - too much time in this case. But other backends have still been - suffering. - - In particular, the xlib backend has often performed quite badly in - this situation. This is due to a bug in the implementation of - trapezoid rasterization in many X servers. - - Now, in cairo 1.4.6 there is a higher-level fix for this - situation. Cairo now eliminates or clips trapezoids that are wholly - or partially outside the clip region before handing the trapezoids - to the backend. This means that the X server's performance bug is - avoided in almost all cases. - - The net result is that doing an extreme zoom-in of vector-based - objects drawn with cairo might have previously brought the X server - to its knees as it allocated buffers large enough to fit all of the - geometry, (whether visible or not). But now the memory usage should - be bounded and performance should be dramatically better. - -Miscellaneous -------------- -Behdad contributed an impressively long series of changes that -organizes cairo's internals in several ways that will be very -beneficial to cairo developers. Thanks, Behdad! - -Behdad has also provided a utility for generating malloc statistics, -(which was used during the great malloc purges of 1.4.2 and -1.4.4). This utility isn't specific to cairo so may be of benefit to -others. It is found in cairo/util/malloc-stats.c and here are Behdad's -notes on using it: - - To build, do: - - make malloc-stats.so - - inside util/, and to use, run: - - LD_PRELOAD=malloc-stats.so some-program - - For binaries managed by libtool, eg, cairo-perf, do: - - ../libtool --mode=execute /bin/true ./cairo-perf - LD_PRELOAD="../util/malloc-stats.so" .libs/lt-cairo-perf - -Finally, the cairo-perf-diff-files utility was enhanced to allow for -generating performance reports from several runs of the same backend -while some system variables were changed. For example, this is now -being used to allow cairo-perf to measure the performance of various -different acceleration architectures and configuration options of the -X.org X server. - -Release 1.4.4 (2007-04-13 Carl Worth <cworth@cworth.org>) -========================================================= -This is the second update release in cairo's stable 1.4 series. It -comes just less than a month after 1.4.2. The changes since 1.4.2 -consist primarily of bug fixes, but also include at least one -optimization. See below for details. - -Of all the work that went into the 1.4.4 release - -There have been lots of individuals doing lots of great work on cairo, -but two efforts during the 1.4.4 series deserve particular mention: - -Internal cleanup of error handling, (Chris Wilson) --------------------------------------------------- -Chris contributed a tremendous series of patches (74 patches!) to -improve cairo's handling of out-of-memory and other errors. He began -by adding gcc's warn_unused_attribute to as many functions as -possible, and then launched into the ambitious efforts of adding -correct code to quiet the dozens of resulting warnings. - -Chris also wrote a custom valgrind skin to systematically inject -malloc failures into cairo, and did all the work necessary to verify -that cairo's performance test suite runs to completion without -crashing. - -The end result is a much more robust implementation. Previously, many -error conditions would have gone unnoticed and would have led to -assertion failures, segmentation faults, or other harder-to-diagnose -problems. Now, more than ever, cairo should cleanly let the user know -of problems through cairo_status and other similar status -functions. Well done, Chris! - -More malloc reduction, (Mathias Hasselmann) -------------------------------------------- -After 1.4.0, Behdad launched an effort to chase down excessive calls -to malloc within the implementation of cairo. He fixed a lot of -malloc-happy objects for 1.4.2, but one of the worst offenders, -(pixman regions), was left around. Mathias contributed an excellent -series of 15 patches to finish off this effort. - -The end result is a cairo that calls malloc much less often than it -did before. Compared to 1.4.2, 55% of the calls to malloc have been -eliminate, (and 60% have been eliminated compared to 1.4.0). Well -done, Mathias! - -Other improvements since 1.4.2 ------------------------------- -• Centralize mutex declarations (will reduce future build breaks), - (Mathias Hasselmann) - -• Reduce malloc by caching recently freed pattern objects (Chris - Wilson) - -• Fix some broken composite operations (David Reveman) - https://bugs.freedesktop.org/show_bug.cgi?id=5777 - -Backend-specific fixes ----------------------- -PDF: - • Use TJ operator for more compact representation of glyphs (Adrian - Johnson) - - • Fix glyph positioning bug when glyphs are not horizontal - http://lists.freedesktop.org/archives/cairo/2007-April/010337.html - -win32: - • Fix crash when rendering with bitmap fonts (Carl Worth) - https://bugzilla.mozilla.org/show_bug.cgi?id=376498 - -xlib: - • Turn metrics-hinting on by default (Behdad Esfahbod) - - • Fix edge-effect problem with transformed images drawn to xlib - (Behdad Esfahbod) - https://bugs.freedesktop.org/show_bug.cgi?id=10508 - - • Avoid dereferencing a NULL screen. (Chris Wilson) - https://bugs.freedesktop.org/show_bug.cgi?id=10517 - -Quartz/ATSUI: - • Fix scaling of glyph surfaces - (Brian Ewins) - https://bugs.freedesktop.org/show_bug.cgi?id=9568 - - • Fix compilation failure when both xlib and quartz enabled - (Brian Ewins) - - • Fix rounding bug leading to incorrectly positioned glyphs - (Robert O'Callahan) - https://bugs.freedesktop.org/show_bug.cgi?id=10531 - -Release 1.4.2 (2007-03-19 Carl Worth <cworth@cworth.org>) -========================================================= -This is the first update release in cairo's stable 1.4 series. It -comes just less than 2 weeks after 1.4.0. We hadn't anticipated an -update this early, but we've managed to collect some important fixes -that we wanted to get out to cairo users as soon as possible, (6 fixes -for crashes, 1 case where graphical elements would not be drawn at -all, a handful of backend-specific bugs, and several important build -fixes). - -There's almost nothing but bug fixes in this release, (see below one -optimization that Behdad did sneak in), so we recommend that everyone -upgrade to this release when possible. - -Thanks to the many people that worked to fix these bugs, and those -that did the work to report them and to test the fixes, (wherever -possible both names are credited below). - -Critical fixes --------------- -• Fix a crash due to a LOCK vs. UNLOCK typo (M. Drochner fixing Carl - Worth's embarrassing typo). - - http://bugs.freedesktop.org/show_bug.cgi?id=10235 - -• Fix potential buffer overflow, which on some systems with a checking - variant of snprintf would lead to a crash (Adrian Johnson, Stanislav - Brabec, and sangu). - - https://bugs.freedesktop.org/show_bug.cgi?id=10267 - https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=232576 - -• Fix a crash in cairo_stroke_extents or cairo_in_stroke when line - width is 0.0. (Carl Worth and Sebastien Bacher) - - https://bugs.freedesktop.org/show_bug.cgi?id=10231 - -• Fix a crash on certain combinations of X server/video drivers (Carl - Worth and Tomas Carnecky). - - https://bugs.freedesktop.org/show_bug.cgi?id=10250 - -• Fix a crash due to mishandling of invalid user input (Carl Worth and - Alexander Darovsky). - - https://bugs.freedesktop.org/show_bug.cgi?id=9844 - -• xlib: Cleanup server-side glyph caches on XCloseDisplay. This - eliminated a crash detected by the perf suite, (and that - applications could have run into as well). (Chris Wilson) - -Other bug fixes ---------------- -• Fix for some geometry which simply disappeared under some - transformations---a stroked line with an extreme skew in X, for - example (Carl Worth and Jonathan Watt). - - https://bugzilla.mozilla.org/show_bug.cgi?id=373632 - -• SVG: Fix radial gradients for CAIRO_EXTEND_REFLECT and when r0 > r1 - (Emmanuel Pacaud). - -• PDF: Set page group color space to DeviceRGB. - - This fixes incorrect (muddy) transparent colors when rendering cairo - PDF output in some viewers. (Adrian Johnson, Adam Goode, and - MenTaLguY). - - http://lists.freedesktop.org/archives/cairo/2006-November/008551.html - -• win32: Return correct metrics when hinting is off, and fix font - descent computation (Behdad Esfahbod). - -• quartz: Fix glyph interfaces to correctly return user-space rather - than device-space coordinates (Brian Ewins). - - https://bugs.freedesktop.org/show_bug.cgi?id=9568 - -• xcb: Fix parameter-order confusion with xcb_create_pixmap, which now - makes all tests that pass with xlib now pass with xcb (Carl Worth, - Jamey Sharp). - -• Fix some memory leaks in the perf suite (Chris Wilson). - -• Fix perf suite to consider changes in pixman/src (Mathias - Hasselmann). - -Build fixes ------------ -• Don't include pre-generated cairo-features.h file. This was causing - build failures when building with the directfb backend enabled - (Behdad Esfahbod). - - https://bugs.freedesktop.org/show_bug.cgi?id=10189 - -• Eliminate use of maintainer mode from cairo's automake/configure - script. This means that updates to files such as Makefile.am will - take effect, (by rerunning automake and friends as necessary) when - invoking make rather than being silently ignored. (Behdad Esfahbod) - -• Don't compile cairo-deflate-stream.c, which depends on zlib, unless - building the pdf backend which requires it. (Carl Worth, Tor - Lillqvist) - - https://bugs.freedesktop.org/show_bug.cgi?id=10202 - -• Don't make the ps backend link against zlib anymore, since it - doesn't require it (Carl Worth). - -• Use "find !" rather than "find -not" for better portability (Thomas - Klausner). - - https://bugs.freedesktop.org/show_bug.cgi?id=10226 - -• Don't use unsupported visibility attribute "hidden" on Solaris - (Gilles Dauphin, Thomas Klausner). - - https://bugs.freedesktop.org/show_bug.cgi?id=10227 - -Optimization ------------- -• It was Behdad that suggested we focus strictly on bug fixes now that - we shipped so many performance improvements in 1.4.0, but it was - also Behdad that got distracted by the chance to remove a lot of - mallocs from cairo. Paths, gstates, trapezoids, splines, polygons, - and gradient color stops will now use small, stack-allocated buffers - in the most common cases rather than calling malloc as - often. (Behdad Esfahbod). And look for more from Mathias Hasselmann - soon. - -Release 1.4.0 (2007-03-06 Carl Worth <cworth@cworth.org>) -========================================================= -The many people[*] who have been working hard on cairo are very -pleased to announce the long-awaited release of cairo 1.4. This -release comes 4 months after the last stable update release (1.2.6) -and 9 months since the initial release of 1.2.0. - -The release notes below are intended to capture the highlights of the -changes that have occurred from the 1.2 series to the new 1.4.0 -release. - -Performance improvements ------------------------- -Within the cairo project, the last 6 months or so has seen an intense -effort focusing on the performance of cairo itself. That effort has -paid off considerably, as can be seen in the following highlights of -some of the performance differences from cairo 1.2.6 to cairo 1.4.0. - -(Note: The performance results reported here were measured on an x86 -laptop. Many of the improvements in 1.4---particular those involving -text rendering---are even more dramatic on embedded platforms without -hardware floating-point units. Such devices played an important part -of many of the optimizations that found their way into cairo over the -last few months.) - -• Dramatic improvement when drawing objects that are mostly off-screen - with the image backend (with the xlib backend this case is still - slow due to an X server bug): - - image-rgba long-lines-uncropped-100 479.64 -> 4.98: 96.24x speedup - ███████████████████████████████████████████████▋ - -• Dramatic improvement when copying a small fraction of an image - surface to an xlib surface: - - xlib-rgba subimage_copy-512 3.93 -> 0.07: 54.52x speedup - ██████████████████████████▊ - -• Dramatic improvement to tessellation speed for complex objects: - - image-rgb tessellate-256-100 874.16 -> 34.79: 25.13x speedup - ████████████■- xlib-rgba zrusin_another_fill-415 148.40 -> 13.85: 10.72x speedup - ████▉ - xlib-rgb world_map-800 680.20 -> 345.54: 1.97x speedup - â–Œ - -• Dramatic improvement to the speed of stroking rectilinear shapes, - (such as the outline of a rectangle or "box"): - - image-rgb box-outline-stroke-100 0.18 -> 0.01: 24.22x speedup - ███████████▋ - xlib-rgb box-outline-stroke-100 0.46 -> 0.06: 8.05x speedup - ███▌ - - -• Dramatic improvements to text rendering speeds: - - xlib-rgba text_image_rgba_over-256 63.12 -> 9.61: 6.57x speedup - ██▊ - -• 3x improvements to floating-point to fixed-point conversion speeds: - - image-rgba pattern_create_radial-16 9.29 -> 3.44: 2.70x speedup - â–‰ - -• 2x improvements to linear gradient computation: - - image-rgb paint_linear_rgb_source-512 26.22 -> 11.61: 2.26x speedup - â–‹ - -• 2x improvement to a case common in PDF rendering: - - image-rgb unaligned_clip-100 0.10 -> 0.06: 1.81x speedup - â– - -• 1.3x improvement to rectangle filling speed (note: this improvement - is new since 1.3.16---previously this test case was a 1.3x slowdown - compared to 1.2.6): - - image-rgba rectangles-512 6.19 -> 4.37: 1.42x speedup - â–Ž - xlib-rgba rectangles-512 7.48 -> 5.58: 1.34x speedup - â– - -NOTE: In spite of our best efforts, there are some measurable -performance regressions in 1.4 compared to 1.2. It appears that the -primary problem is the increased overhead of the new tessellator when -drawing many, very simple shapes. The following test cases capture -some of that slowdown: - - image-rgba mosaic_tessellate_lines-800 11.03 -> 14.29: 1.30x slowdown - â– - image-rgba box-outline-fill-100 0.01 -> 0.01: 1.26x slowdown - â– - image-rgba fill_solid_rgb_over-64 0.20 -> 0.22: 1.12x slowdown - - image-rgba fill_image_rgba_over-64 0.23 -> 0.25: 1.10x slowdown - - xlib-rgb paint_image_rgba_source-256 3.24 -> 3.47: 1.07x slowdown - -We did put some special effort into eliminating this slowdown for the -very common case of drawing axis-aligned rectangles with an identity -matrix (see the box-outline-stroke and rectangles speedup numbers -above). Eliminating the rest of this slowdown will be a worthwhile -project going forward. - -Also note that the "box-outline-fill" case is a slowdown while -"box-outline-stroke" is a (huge) speedup. These two test cases -resulted from the fact that some GTK+ theme authors were filling -between two rectangles to avoid slow performance from the more natural -means of achieving the same shape by stroking a single rectangle. With -1.4 that workaround should definitely be eliminated as it will now -cause things to perform more slowly. - -Greatly improved PDF output ---------------------------- -We are very happy to be able to announce that cairo-generated PDF -output will now have text that can be selected, cut-and-pasted, and -searched with most capable PDF viewer applications. This is something -that was not ever possible with cairo 1.2. - -Also, the PDF output now has much more compact encoding of text than -before. Cairo is now much more careful to not embed multiple copies of -the same font at different sizes. It also compresses text and font -streams within the PDF output. - -API additions -------------- -There are several new functions available in 1.4 that were not -available in 1.2. Curiously, almost all of the new functions simply -allow the user to query state that has been set in cairo (many new -"get" functions) rather than providing any fundamentally new -operations. The new functionality is: - -• Getting information about the current clip region - - cairo_clip_extents - cairo_copy_clip_rectangle_list - cairo_rectangle_list_destroy - -• Getting information about the current dash setting - - cairo_get_dash_count - cairo_get_dash - -• Getting information from a pattern - - cairo_pattern_get_rgba - cairo_pattern_get_surface - cairo_pattern_get_color_stop_rgba - cairo_pattern_get_color_stop_count - cairo_pattern_get_linear_points - cairo_pattern_get_radial_circles - -• Getting the current scaled font - - cairo_get_scaled_font - -• Getting reference counts - - cairo_get_reference_count - cairo_surface_get_reference_count - cairo_pattern_get_reference_count - cairo_font_face_get_reference_count - cairo_scaled_font_get_reference_count - -• Setting/getting user data on objects - - cairo_set_user_data - cairo_get_user_data - cairo_pattern_set_user_data - cairo_pattern_get_user_data - cairo_scaled_font_set_user_data - cairo_scaled_font_get_user_data - -• New cairo-win32 functions: - - cairo_win32_surface_create_with_ddb - cairo_win32_surface_get_image - cairo_win32_scaled_font_get_logical_to_device - cairo_win32_scaled_font_get_device_to_logical - -API deprecation ---------------- -The CAIRO_FORMAT_RGB16_565 enum value has been deprecated. It never -worked as a format value for cairo_image_surface_create, and it wasn't -necessary for supporting 16-bit 565 X server visuals. - -A sampling of bug fixes in cairo 1.4 ------------------------------------- - • Fixed radial gradients - • Fixed dashing (degenerate and "leaky" cases) - • Fixed transformed images in PDF/PS output (eliminate bogus repeating) - • Eliminate errors from CAIRO_EXTEND_REFLECT and CAIRO_EXTEND_PAD - • cairo_show_page no longer needed for single-page output - • SVG: Fix bug preventing text from appearing in many viewers - • cairo-ft: Return correct metrics when hinting is off - • Eliminate crash in cairo_create_similar if nil surface is returned - • Eliminate crash after INVALID_RESTORE error - • Fix many bugs related to multi-threaded use and locking - • Fix for glyph spacing 32 times larger than desired (cairo-win32) - • Fixed several problems in cairo-atsui (assertion failures) - • Fix PDF output to avoid problems when printing from Acrobat Reader - • Fix segfault on Mac OS X (measuring a zero-length string) - • Fix text extents to not include the size of non-inked characters - • Fix for glyph cache race condition in glitz backend (Jinghua Luo) - • Fix make check to work on OPD platforms (IA64 or PPC64) - • Fix compilation problems of cairo "wideint" code on some platforms - • Many, many others... - -Experimental backends (quartz, XCB, OS/2, BeOS, directfb) ---------------------------------------------------------- -None of cairo's experimental backends are graduating to "supported" -status with 1.4.0, but two of them in particular (quartz and xcb), are -very close. - -The quartz baceknd has been entirely rewritten and is now much more -efficient. The XCB backend has been updated to track the latest XCB -API (which recently had a 1.0 release). - -We hope to see these backends become supported in a future release, -(once they are passing all the tests in cairo's test suite). - -The experimental OS/2 backend is new in cairo 1.4 compared to cairo -1.2. - -Documentation improvements --------------------------- -We have added documentation for several functions and types that -were previously undocumented, and improved documentation on other -ones. As of this release, there remain only two undocumented -symbols: cairo_filter_t and cairo_operator_t. - -[*]Thanks to everyone ---------------------- -I've accounted for 41 distinct people with attributed code added to -cairo between 1.2.6 and 1.4.0, (their names are below). That's an -impressive number, but there are certainly dozens more that -contributed with testing, suggestions, clarifying questions, and -encouragement. I'm grateful for the friendships that have developed as -we have worked on cairo together. Thanks to everyone for making this -all so much fun! - -Adrian Johnson, Alfred Peng, Alp Toker, Behdad Esfahbod, -Benjamin Otte, Brian Ewins, Carl Worth, Christian Biesinger, -Christopher (Monty) Montgomery, Daniel Amelang, Dan Williams, -Dave Yeo, David Turner, Emmanuel Pacaud, Eugeniy Meshcheryakov, -Frederic Crozat, Hans Breuer, Ian Osgood, Jamey Sharp, Jeff Muizelaar, -Jeff Smith, Jinghua Luo, Jonathan Watt, Joonas Pihlaja, Jorn Baayen, -Kalle Vahlman, Kjartan Maraas, Kristian Høgsberg, M Joonas Pihlaja, -Mathias Hasselmann, Mathieu Lacage, Michael Emmel, Nicholas Miell, -Pavel Roskin, Peter Weilbacher, Robert O'Callahan, -Soren Sandmann Pedersen, Stuart Parmenter, T Rowley, -Vladimir Vukicevic - -Snapshot 1.3.16 (2007-03-02 Carl Worth <cworth@cworth.org>) -=========================================================== -New API functions ------------------ -A few new public functions have been added to the cairo API since the -1.3.14 snapshot. These include a function to query the current scaled -font: - - cairo_get_scaled_font - -New functions to query the reference count of all cairo objects: - - cairo_get_reference_count - - cairo_surface_get_reference_count - cairo_pattern_get_reference_count - - cairo_font_face_get_reference_count - cairo_scaled_font_get_reference_count - -And new functions to allow the use of user_data with any cairo object, -(previously these were only available on cairo_surface_t and -cairo_font_face_t objects): - - cairo_set_user_data - cairo_get_user_data - - cairo_pattern_set_user_data - cairo_pattern_get_user_data - - cairo_scaled_font_set_user_data - cairo_scaled_font_get_user_data - -Usability improvement for PDF/PS/SVG generation ------------------------------------------------ -In previous versions of cairo, generating single-page output with the -cairo-pdf, cairo-ps, or cairo-svg backends required a final call to -cairo_show_page. This was often quite confusing as people would port -functional code from a non-paginated backend and be totally mystified -as to why the output was blank until they learned to add this call. - -Now that call to cairo_show_page is optional, (it will be generated -implicitly if the user does not call it). So cairo_show_page is only -needed to explicitly separate multiple pages. - -Greatly improved PDF output ---------------------------- -We are very happy to be able to announce that cairo-generated PDF -output will now have text that can be selected, cut-and-paste, and -searched with most capable PDF viewer applications. This is something -that was not ever possible with cairo 1.2. - -Also, the PDF output now has much more compact encoding of text than -before. Cairo is now much more careful to not embed multiple copies of -the same font at different sizes. It also compresses text and font -streams within the PDF output. - -Major bug fixes ---------------- - • Fixed radial gradients - - The rendering of radial gradients has been greatly improved. In - the cairo 1.2 series, there was a serious regression affecting - radial gradients---results would be very incorrect unless one of - the gradient circles had a radius of 0.0 and a center point within - the other circle. These bugs have now been fixed. - - • Fixed dashing - - Several fixes have been made to the implementation of dashed - stroking. Previously, some dashed, stroked rectangles would - mis-render and fill half of the rectangle with a large triangular - shape. This bug has now been fixed. - - • Fixed transformed images in PDF/PS output - - In previous versions of cairo, painting with an image-based source - surface pattern to the PDF or PS backends would cause many kinds - of incorrect results. One of the most common problems was that an - image would be repeated many times even when the user had - explicitly requested no repetition with CAIRO_EXTEND_NONE. These - bugs have now been fixed. - - • Eliminate errors from CAIRO_EXTEND_REFLECT and CAIRO_EXTEND_PAD - - In the 1.2 version of cairo any use of CAIRO_EXTEND_REFLECT or - CAIRO_EXTEND_PAD with a surface-based pattern resulted in an - error, (cairo would stop rendering). This bug has now been - fixed. - - Now, CAIRO_EXTEND_REFLECT should work properly with surface - patterns. - - CAIRO_EXTEND_PAD is still not working correctly, but it will now - simply behave as CAIRO_EXTEND_NONE rather than triggering the - error. - -New rewrite of quartz backend (still experimental) --------------------------------------------------- -Cairo's quartz backend has been entirely rewritten and is now much -more efficient. This backend is still marked as experimental, not -supported, but it is now much closer to becoming an officially -supported backend. (For people that used the experimental nquartz -backend in previous snapshots, that implementation has now been -renamed from "nquartz" to "quartz" and has replaced the old quartz -backend.) - -Documentation improvements --------------------------- -We have added documentation for several functions and types that -were previously undocumented, and improved documentation on other -ones. As of this release, there remain only two undocumented -symbols: cairo_filter_t and cairo_operator_t. - -Other bug fixes ---------------- - • cairo-svg: Fix bug that was preventing text from appearing in many - viewers - - • cairo-ft: Return correct metrics when hinting is off - - • Cairo 1.3.14 deadlocks in cairo_scaled_font_glyph_extents or - _cairo_ft_unscaled_font_lock_face - - https://bugs.freedesktop.org/show_bug.cgi?id=10035 - - • cairo crashes in cairo_create_similar if nil surface returned by - other->backend->create_similar - - https://bugs.freedesktop.org/show_bug.cgi?id=9844 - - • evolution crash in _cairo_gstate_backend_to_user() - https://bugs.freedesktop.org/show_bug.cgi?id=9906 - - • Fix memory leak in rectilinear stroking code - -Things not in this release --------------------------- - • Solid-surface-pattern cache: This patch had been applied during - the 1.3.x series, but it was reverted due to some inter-thread - problems it caused. The patch is interesting since it made a big - benefit for text rendering performance---so we'll work to bring a - corrected version of this patch back as soon as possible. - -Snapshot 1.3.14 (2006-02-13 Carl Worth <cworth@cworth.org>) -=========================================================== -This is the seventh development snapshot in the 1.3 series, (and there -likely won't be many more before the 1.4.0 release). It comes just -over 3 weeks after the 1.3.12 snapshot. - -Since we're so close to the 1.4.0 release, there are not a lot of new -features nor even a lot of new performance improvements in this -snapshot. Instead, there are a great number of bug fixes. Some are -long-standing bugs that we're glad to say goodbye to, and several are -fixes for regressions that were introduced as part of the optimization -efforts during the 1.3.x series. - -PDF text selection fixed ------------------------- -The inability to correctly select text in cairo-generated PDF has been -a defect ever since the initial support for the PDF backend in the -cairo 1.2.0 release. With the 1.3.14 snapshot, in most situations, and -with most PDF viewer applications, the PDF generated by cairo will -allow text to be correctly selected for copy-and-paste, (as well as -searching). - -We're very excited about this new functionality, (and very grateful to -Adrian Johnson, Behdad Esfahbod, and others that have put a lot of -work into this lately). Please test this new ability and give feedback -on the cairo@cairographics.org list. - -Many thread-safety issues fixed -------------------------------- -We've discovered that no release of cairo has ever provided safe text -rendering from a multi-threaded application. With the 1.3.14 snapshot -a huge number of the bugs in this area have been fixed, and multiple -application dvelopers have now reported success at writing -multi-threaded applications with cairo. - -Other fixes ------------ -Fixed a bug that was causing glyph spacing to be 32 times larger than -desired when using cairo-win32. - -Fixed a regression in the rendering of linear gradients that had been -present since the 1.3.8 snapshot. - -Fixed several problems in cairo-atsui that were leading to assertion -failures when rendering text. - -Fix corrupted results when rendering a transformed source image -surface to an xlib surface. This was a regression that had been -present since the 1.3.2 snapshot. - -Fixed PDF output to prevent problems printing from some versions of -Acrobat Reader, (a single glyph was being substituted for every -glyph). - -And many other fixes as well, (see the logs for details). - -Snapshot 1.3.12 (2007-01-20 Carl Worth <cworth@cworth.org>) -=========================================================== -The relentless march toward the cairo 1.4 release continues, (even if -slightly late out of the starting blocks in 2007). This is the sixth -development snapshot in the 1.3 series. It comes 4 weeks after the -1.3.10 snapshot. - -Performance ------------ -As usual, this snapshot has some fun performance improvements to show -off: - -image-rgba long-lines-uncropped-100 470.08 -> 4.95: 94.91x speedup -███████████████████████████████████████████████ -image-rgb long-lines-uncropped-100 461.60 -> 4.96: 93.02x speedup -██████████████████████████████████████████████ - -This 100x improvement, (and yes, that's 100x, not 100%), in the image -backend occurs when drawing large shapes where only a fraction of the -shape actually appears in the final result, (the rest being outside -the bounds of the destination surface). Many applications should see -speedups here, and the actual amount of speedup depends on the ratio -of non-visible to visible portions of geometry. - -[Note: There remains a similar performance bug when drawing mostly -non-visible objects with the xlib backend. This is due to a similar -bug in the X server itself, but we hope a future cairo snapshot will -workaround that bug to get a similar speedup with the xlib backend.] - -image-rgba unaligned_clip-100 0.09 -> 0.06: 1.67x speedup -â– -image-rgb unaligned_clip-100 0.09 -> 0.06: 1.66x speedup -â– - -This speedup is due to further MMX optimization by Soeren Sandmann for -a case commonly hit when rendering PDF files, (and thanks to Jeff -Muizelaar for writing code to extract the test case for us). - -There's another MMX optimization in this snapshot (without a fancy -speedup chart) by Dan Williams which improves compositing performance -specifically for the OLPC machine. - -Thanks to Adrian Johnson, cairo's PDF output is now much more -efficient in the way it encodes text output. By reducing redundant -information and adding compression to text output streams, Adrian -achieved a ~25x improvement in the efficiency of encoding text in PDF -files, (was ~45 bytes per glyph and is now ~1.6 bytes per glyph). - -Bug fixes ---------- -In addition to those performance improvements, this snapshot includes -several bug fixes: - - * A huge number of bug fixes for cairo-atsui text rendering, (for mac - OS X). These bugs affect font selection, glyph positioning, glyph - rendering, etc. One noteworthy bug fixes is that - cairo_select_font_face will no longer arbitrarily select bold nor - italic when not requested, (at least not when using a standard CSS2 - font family name such as "serif", "sans-serif", "monospace", etc.). - All these fixes are thanks to Brian Ewins who continues to do a - great job as the new cairo-atsui maintainer. - - * Fix PDF output so that images that are scaled down no longer - mysteriously repeat (Carl Worth). - - * Fix segfault on Mac OS X dues to attempt to measure extents of a - zero-length string (Behdad Esfahbod). - - * Fix text extents to not include the size of initial/trailing - non-inked characters (Behdad Esfahbod). - -API tweaks ----------- -Three functions have had API changes to improve consistency. Note that -the API functions being changed here are all functions that were -introduced as new functions during these 1.3.x snapshots. As always, -there will not be any API changes to functions included in a major -release (1.2.x, 1.4.x, etc.) of cairo. - -The changes are as follows: - - * Rename of cairo_copy_clip_rectangles to cairo_copy_clip_rectangle_list. - - * Change cairo_get_dash_count to return an int rather than accepting a - pointer to an int for the return value. - - * Change cairo_get_dash to have a void return type rather than - returning cairo_status_t. - -It's possible there will be one more round of changes to these -functions, (and perhaps cairo_get_color_stop as well), as we seek to -establish a unifying convention for returning lists of values. - -Snapshot 1.3.10 (2006-12-23 Carl Worth <cworth@cworth.org>) -=========================================================== -Santa Claus is coming just a little bit early this year, and he's -bringing a shiny new cairo snapshot for all the good little boys and -girls to play with. - -This is the fifth development snapshot in the 1.3 series. It comes 9 -days after the 1.3.8 snapshot, and still well within our goal of -having a new snapshot every week, (though don't expect one next -week---we'll all be too stuffed with sugar plums). - -Speaking of sugar plums, there's a sweet treat waiting in this cairo -snapshot---greatly improved performance for stroking rectilinear -shapes, like the ever common rectangle: - -image-rgb box-outline-stroke-100 0.18 -> 0.01: 25.58x speedup -████████████████████████▋ -image-rgba box-outline-stroke-100 0.18 -> 0.01: 25.57x speedup -████████████████████████▋ -xlib-rgb box-outline-stroke-100 0.49 -> 0.06: 8.67x speedup -███████▋ -xlib-rgba box-outline-stroke-100 0.22 -> 0.04: 5.39x speedup -████■- -In past releases of cairo, some people had noticed that using -cairo_stroke to draw rectilinear shapes could be awfully slow. Many -people had worked around this by using cairo_fill with a more complex -path and gotten a 5-15x performance benefit from that. - -If you're one of those people, please rip that workaround out, as now -the more natural use of cairo_stroke should be 1.2-2x faster than the -unnatural use of cairo_fill. - -And if you hadn't ever implemented that workaround, then you just -might get to see your stroked rectangles now get drawn 5-25x faster. - -Beyond that performance fix, there are a handful of bug fixes in this -snapshot: - - * Fix for glyph cache race condition in glitz backend (Jinghua Luo) - - * Many fixes for ATSUI text rendering (Brian Ewins) - - * Un-break recent optimization-triggered regression in rendering text - with a translation in the font matrix (Behdad Esfahbod) - - * Fix make check to work on OPD platforms (IA64 or PPC64) - (Frederic Crozat) - - * Fix a couple of character spacing issues on Windows - (Jonathan Watt) - -Have fun with that, everybody, and we'll be back for more in the new -year, (with a plan to add the last of our performance improvements in -this round, fix a few bad, lingering bugs, and then finish off a nice, -stable 1.4 release before the end of January). - --Carl - -Snapshot 1.3.8 (2006-12-14 Carl Worth <cworth@cworth.org>) -========================================================== -This is the fourth development snapshot in the 1.3 series. It comes -just slightly more than one week after the 1.3.6 snapshot. - -After the bug fixes in 1.3.6, we're back to our original program of -weekly snapshots, each one faster than the one from the week -before. Cairo 1.3.8 brings a 2x improvement in the speed of rendering -linear gradients (thanks to David Turner), and a significant reduction -in X traffic when rendering text (thanks to Xan Lopez and Behdad -Esfahbod), making cairo behave very much like Xft does. - -A few other things in the 1.3.8 snapshot worth noting include a more -forgiving image comparator in the test suite, (using the "perceptual -diff" metric and GPL implementation by Hector Yee[*]), a bug fix for -broken linking on x86_64 (thanks to M Joonas Pihlaja) and an even -better implementation of _cairo_lround, (not faster, but supporting a -more complete input range), from Daniel Amelang. - -[*] http://pdiff.sourceforge.net/ - -Snapshot 1.3.6 (2006-12-06 Carl Worth <cworth@cworth.org>) -========================================================== -This is the third development snapshot in the 1.3 series. It comes two -weeks after the 1.3.4 snapshot. - -We don't have fancy performance charts this week as the primary -changes in this snapshot are bug fixes. The performance work continues -and the next snapshot (planned for one week from today) should include -several improvements. The bug fixes in this snapshot include: - - * Fix undesirable rounding in glyph positioning (Dan Amelang) - - This bug was noticed by several users, most commonly by seeing - improper text spacing or scrambled glyphs as drawn by nautilus. For - example: - - Update to cairo-1.3.4 worsen font rendering - https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=217819 - - * Fix reduced range of valid input coordinates to tessellator - (M Joonas Pihlaja) - - This bug was causing lots of assertion failures in mozilla as - mentioned here: - - CAIRO_BO_GUARD_BITS and coordinate space? - http://lists.freedesktop.org/archives/cairo/2006-December/008743.html - - * Fix several regressions in new tessellator (M Joonas Pihlaja) - - Joonas just had a good eye for detail here. I don't think any - external cairo users had noticed any of these bugs yet. - - * Fix compilation problems of cairo "wideint" code on some platforms - (Mathieu Lacage) - - * Fix failed configure due to broken grep (Dan Amelang) - - This bug was reported here: - - AX_C_FLOAT_WORDS_BIGENDIAN doesn't work because grep doesn't - work with binary file - https://bugs.freedesktop.org/show_bug.cgi?id=9124 - - * Remove the pkg-config minimum version requirement (Behdad Esfahbod) - - Some systems ship with pkg-config 0.15 and there was really no good - reason for cairo to insist on having version 0.19 before it would - build. - -There is also one new (but inert) feature in this snapshot. There's a -new option that can be passed to cairo's configure script: - - --disable-some-floating-point - - Disable certain code paths that rely heavily on double precision - floating-point calculation. This option can improve - performance on systems without a double precision floating-point - unit, but might degrade performance on those that do. - -As of this snapshot, this option does not make any change to cairo, -but it is possible that future versions of cairo will respect this -option and change the implementation of various functions as -appropriate. - -Snapshot 1.3.4 (2006-11-22 Carl Worth <cworth@cworth.org>) -========================================================== -This is the second development snapshot in the 1.3 series. It comes -one week after the 1.3.2 snapshot. - -This snapshot has a couple of significant performance improvements, -and also adds new support for producing multi-page SVG output, (when -targeting SVG 1.2)---thanks to Emmanuel Pacaud. The details of the -performance improvements are as follows: - -1. The long-awaited "new tessellator". - - The credit for this being an improvement goes to Joonas Pihlaja. He - took my really slow code and really put it through its paces to get - the dramatic performance improvement seen below (up to 38x faster - on realistic cases, and more than 10x faster for the zrusin_another - test). - - His own writeup of the work he did is quite thorough, but more than - can be quoted here. Please see his post for the interesting details: - - http://lists.freedesktop.org/archives/cairo/2006-November/008483.html - - (Though note that this snapshot also includes some additional, - significant improvements that were only sketched out in that - email---see "Generating fewer trapezoids"). - -2. More floating-point improvements - - Daniel Amelang continues to work the magic he began in the 1.3.2 - snapshot. This time he short-circuits floating-point - transformations by identity matrices and applies the earlier - floating-to-fixed-point technique to the problem of rounding. - - The improvements here will primarily benefit text performance, and - will benefit platforms without hardware floating-point more than - those that have it, (some text tests show 20% improvement on an x86 - machine and closer to 80% improvement on arm). - -The performance chart comparing 1.3.2 to 1.3.4 really speaks for -itself, (this is on an x86 laptop).

But more importantly, it contains some new -API in preparation for a future 1.4 release, and most importantly, it -contains several performance improvements. - -The bug fixes will not be reviewed here, as most of them are already -described in the 1.2.6 release notes. But details for the new API and -some performance improvements are included here. - -As with all snapshots, this is experimental code, and the new API -added here is still experimental and is not guaranteed to appear -unchanged in any future release of cairo. - -API additions -------------- -Several new API additions are available in this release. There is a -common theme among all the additions in that they allow cairo to -advertise information about its state that it was refusing to -volunteer earlier. So this isn't groundbreaking new functionality, but -it is essential for easily achieving several tasks. - -The new functions can be divided into three categories: - - Getting information about the current clip region - ------------------------------------------------- - cairo_clip_extents - cairo_copy_clip_rectangles - cairo_rectangle_list_destroy - - Getting information about the current dash setting - -------------------------------------------------- - cairo_get_dash_count - cairo_get_dash - - Getting information from a pattern - ---------------------------------- - cairo_pattern_get_rgba - cairo_pattern_get_surface - cairo_pattern_get_color_stop_rgba - cairo_pattern_get_color_stop_count - cairo_pattern_get_linear_points - cairo_pattern_get_radial_circles - -In each of these areas, we have new API for providing a list of -uniform values from cairo. The closest thing we had to this before was -cairo_copy_path, (which is rather unique in providing a list of -non-uniform data). - -The copy_clip_rectangles/rectangle_list_destroy functions follow a -style similar to that of cairo_copy_path. Meanwhile, the dash and -pattern color stop functions introduce a new style in which there is a -single call to return the number of elements available (get_dash_count -and get_color_stop_count) and then a function to be called once to get -each element (get_dash and get_color_stop_rgba). - -I'm interested in hearing feedback from users of these new API -functions, particularly from people writing language bindings. One -open question is whether the clip "getter" functionality should adopt -a style similar to that of the new dash and color_stop interfaces. - -API deprecation ---------------- -The CAIRO_FORMAT_RGB16_565 enum value has been deprecated. It never -worked as a format value for cairo_image_surface_create, and it wasn't -necessary for supporting 16-bit 565 X server visuals. - -XCB backend changes -------------------- -The XCB backend has been updated to track the latest XCB API (which -recently had a 1.0 release). - -New quartz backend ------------------- -Vladimir Vukicevic has written a new "native quartz" backend which -will eventually replace the current "image-surface wrapping" quartz -backend. For now, both backends are available, (the old one is -"quartz" and the new one is "nquartz"). But it is anticipated that the -new backend will replace the old one and take on the "quartz" name -before this backend is marked as supported in a release of cairo. - -New OS/2 backend ----------------- -Doodle and Peter Weilbacher have contributed a new, experimental -backend for using cairo on OS/2 systems. - -Performance improvements ------------------------- -Here are some highlights from cairo's performance suite showing -improvements from cairo 1.2.6 to cairo 1.3.2. The command used to -generate this data is: - - ./cairo-perf-diff 1.2.6 HEAD - -available in the perf/ directory of a recent checkout of cairo's -source, (the cairo-perf-diff script does require a git checkout and -will not work from a tar file---though ./cairo-perf can still be used -to generate a single report there and ./cairo-perf-diff-files can be -used to compare two reports). - -Results are described below both for an x86 laptop (with an old Radeon -video card, recent X.org build, XAA, free software drivers), as well -as for a Nokia 770. First the x86 results with comments on each, (all -times are reported in milliseconds). - -Copying subsets of an image surface to an xlib surface (much faster) --------------------------------------------------------------------- - xlib-rgba subimage_copy-512 10.50 -> : 53.97x speedup -█████████████████████████████████████████████████████ - -Thanks to Christopher (Monty) Montgomery for this big performance -improvement. Any application which has a large image surface and is -copying small pieces of it at a time to an xlib surface, (imagine an -application that loads a single image containing all the "sprites" for -that application), will benefit from this fix. The larger the ratio of -the image surface to the portion being copied, the larger the benefit. - -Floating-point conversion (3x faster) -------------------------------------- - xlib-rgba pattern_create_radial-16 27.75 -> 3.93 : 2.94x speedup -██ -image-rgb pattern_create_radial-16 26.06 -> 3.74 : 2.90x speedup -█▉ - -Thanks to Daniel Amelang, (and others who had contributed the idea -earlier), for this nice improvement in the speed of converting -floating-point values to fixed-point. - -Text rendering (1.3 - 2x faster) ------------------------------- - xlib-rgba text_image_rgba_source-256 319.73 -> 62.40 : 2.13x speedup -█■-image-rgb text_solid_rgba_over-64 2.85 -> 0.88 : 1.35x speedup -â– - -I don't think we've ever set out to improve text performance -specifically, but we did it a bit anyway. I believe the extra -improvement in the xlib backend is due to Monty's image copying fix -above, and the rest is due to the floating-point conversion speedup. - -Thin stroke improvements (1.5x faster) ---------------------------------------------- -image-rgb world_map-800 1641.09 -> 414.77 : 1.65x speedup -â–‹ - xlib-rgba world_map-800 1939.66 -> 529.94 : 1.52x speedup -â–Œ - -The most modest stuff to announce in this release is the 50% -improvement I made in the world_map case. This is in improvement that -should help basically anything that is doing strokes with many -straight line segments, (and the thinner the better, since that makes -tessellation dominate rasterization). The fixes here are to use a -custom quadrilateral tessellator rather than the generic tessellator -for straight line segments and the miter joins. - -Performance results from the Nokia 770 --------------------------------------- - xlib-rgba subimage_copy-512 55.88 -> 2.04 : 27.34x speedup -██████████████████████████■- xlib-rgb text_image_rgb_over-256 1487.58 -> 294.43 : 5.05x speedup -████ -image-rgb pattern_create_radial-16 187.13 -> 91.86 : 2.04x speedup -â–ˆ - xlib-rgba world_map-800 21261.41 -> 15628.02 : 1.36x speedup -â– - -Here we see that the subimage_copy improvement was only about half as -large as the corresponding improvement on my laptop, (27x faster -compared to 54x) and the floating-point conversion fix also was quite -as significant, (2x compared to 3x). Oddly the improvement to text -rendering performance was more than twice as good (5x compared to -2x). I don't know what the reason for that is, but I don't think it's -anything anybody should complain about. - -Release 1.2.6 (2006-11-02 Behdad Esfahbod <behdad@behdad.org>) -============================================================== -This is the third bug fix release in the 1.2 series, coming less than -two months after the 1.2.4 release made on August 18. - -The 1.2.4 release turned out to be a pretty solid one, except for a crasher -bug when forwarding an X connection where the client and the server have -varying byte orders, eg. from a PPC to an i686. Other than that, various -other small bugs have been fixed. - -Various improvements have been made in the testing infrastructure to prevent -false positives, and to make sure the generated cairo shared object behaves as -expected in terms of exported symbols and relocations. - -There were a total of 89 changes since 1.2.4. The following list the most -important ones: - -Common fixes ------------- -- Avoid unsigned loop control variable to eliminate infinite, - memory-scribbling loop. (#7593) -- Fix cairo_image_surface_create to report INVALID_FORMAT errors. - Previously the detected error was being lost and a nil surface was - returned that erroneously reported CAIRO_STATUS_NO_MEMORY. -- Change _cairo_color_compute_shorts to not rely on any particular - floating-point epsilon value. (#7497) -- Fix infinite-join test case (bug #8379) -- Pass correct surface to create_similar in _cairo_clip_init_deep_copy(). - -PS/PDF fixes ------------- -- Fix Type 1 embedding in PDF. -- Correct the value of /LastChar in the PDF Type 1 font dictionary. -- Improve error checking in TrueType subsetting. -- Compute right index when looking up left side bearing. (bug #8180) -- Correct an unsigned to signed conversion problem in truetype subsetting - bbox. -- Type1 subsetting: Don't put .notdef in Encoding when there are 256 glyphs. -- Add cairo version to PS header / PDF document info dictionary. -- Set CTM before path construction. - -Win32 fixes ------------ -- Get correct unhinted outlines on win32. (bug 7603) -- Make cairo as a win32 static library possible. -- Use CAIRO_FORMAT_RGB24 for BITSPIXEL==32 surfaces too. - -Build system fixes ------------------- -- Define WINVER if it's not defined. (bug 6456) -- Fix the AMD64 final link by removing SLIM from pixman. -- Misc win32 compilation fixes. -- Add Sun Pro C definition of pixman_private. -- Use pixman_private consistently as prefix not suffix. -- Added three tests check-plt.sh, check-def.sh, and check-header.sh that check - that the shared object, the .def file, and the public headers agree about - the exported symbols. -- Require pkg-config 0.19. (#8686) - - -Release 1.2.4 (2006-08-18 Carl Worth <cworth@cworth.org>) -========================================================= -This is the second bug fix release in the 1.2 series, coming less than -two weeks after the 1.2.2 release made on August 8. - -The big motivation for a quick release was that there were a log of -build system snags that people ran into with the 1.2.2 release. But, -by the time we got those all done, we found that we had a bunch of -fixes for cairo's rendering as well. So there's a lot of goodness in -here for such a short time period. - -Rendering fixes ---------------- -Fix image surfaces to not be clipped when used as a source (Vladimir Vukicevic) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=72e25648c4c4bc82ddd938aa4e05887a293f0d8b - -Fix a couple of corner cases in dashing degenerate paths (Jeff Muizelaar) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=fbb1758ba8384650157b2bbbc93d161b0c2a05f0 - -Fix support for type1 fonts on win32 (Adrian Johnson) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=da1019c9138695cb838a54f8b871bbfd0e8996d7 - -Fix assertion failure when rotating bitmap fonts (Carl Worth) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=0bfa6d4f33b8ddb5dc55bbe419c15df4af856ff9 - -Fix assertion failure when calling cairo_text_path with bitmap fonts (Carl Worth) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=9878a033531e6b96b5f27e69e10e90dee7440cd9 - -Fix mis-handling of cairo_close_path in some situations (Tim Rowley, Carl Worth) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=53f74e59faf1af78f2f0741ccf1f23aa5dad4efc - -Respect font_matrix translation in _cairo_gstate_glyph_path (Behdad Esfahbod) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=f183b835b111d23e838889178aa8106ec84663b3 - -Fix vertical metrics adjustment to work with non-identity shapes (Behdad Esfahbod) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=b7bc263842a798d657a95e539e1693372448837f - -[PS] Set correct ImageMatrix in _cairo_ps_surface_emit_bitmap_glyph_data (Behdad Esfahbod) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=d47388ad759b0a1a0869655a87d9b5eb6ae2445d - -Build system fixes ------------------- -Fix xlib detection to prefer pkg-config to avoid false libXt dependency (Behdad Esfahbod) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=0e78e7144353703cbd28aae6a67cd9ca261f1d68 - -Fix typos causing win32 build problem with PS,PDF, and SVG backends (Behdad Esfahbod) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=aea83b908d020e26732753830bb3056e6702a774 - -Fix configure cache to not use stale results (Behdad Esfahbod) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=6d0e3260444a2d5b6fb0cb223ac79f1c0e7b3a6e - -Fix to not pass unsupported warning options to the compiler (Jens Granseuer) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=97524a8fdb899de1ae4a3e920fb7bda6d76c5571 - -Fix to allow env. variables such as png_REQUIRES to override configure detection (Jens Granseuer) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=abd16e47d6331bd3811c908e524b4dcb6bd23bf0 - -Fix test suite to not use an old system cairo when converting svg2png (Behdad Esfahbod) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=6122cc85c8f71b1ba2df3ab86907768edebe1781 - -Fix test suite to not require signal.h to be present (Behdad Esfahbod) -http://gitweb.freedesktop.org/?p=cairo;a=commit;h=6f8cf53b1e1ccdbe1ab6a275656b19c6e5120e40 - -Code cleanups -------------- -Many useful warnings cleanups from sparse, valgrind, and careful eyes -(Kjartan Maraas, Pavel Roskin) - -Release 1.2.2 (2006-08-08 Carl Worth <cworth@cworth.org>) -========================================================= -This is the first bug fix release in the 1.2 series since the original -1.2.0 release made six weeks ago. - -There were some very serious bugs in the 1.2.0 release, (see below), -so everybody is encouraged to upgrade from 1.2.0 to 1.2.2. The 1.2.2 -release maintains source and binary compatibility with 1.2.0 and does -not make any API additions. - -Fix crashes with BGR X servers ------------------------------- -With cairo 1.2.0 many people reported problems with all cairo-using -programs, (including all GTK+ programs with GTK+ >= 2.8) immediately -crashing with a complaint about an unsupported image format. This bug -affected X servers that do not provide the Render extension and that -provide a visual with BGR rather than RGB channel order. - -report: https://bugs.freedesktop.org/show_bug.cgi?id=7294 -fix: http://gitweb.freedesktop.org/?p=cairo;a=commit;h=9ae66174e774b57f16ad791452ed44efc2770a59 - -Fix the "disappearing text" bug -------------------------------- -With cairo 1.2.0 many people reported that text would disappear from -applications, sometimes reappearing with mouse motion or -selection. The text would disappear after the first space in a string -of text. This bug was caused by an underlying bug in (very common) X -servers, and only affected text rendered without antialiasing, (either -a bitmap font or a vector font with antialiasing disabled). The bug -was also exacerbated by a KDE migration bug that caused antialiasing -to be disabled more than desired. - -report: https://bugs.freedesktop.org/show_bug.cgi?id=7494 -fix: http://gitweb.freedesktop.org/?p=cairo;a=commit;h=456cdb3058f3b416109a9600167cd8842300ae14 -see also: -Xorg: https://bugs.freedesktop.org/show_bug.cgi?id=7681 -KDE: http://qa.mandriva.com/show_bug.cgi?id=23990 - -Fix broken image fallback scaling (aka. "broken printing") ----------------------------------------------------------- -The various "print" backends, (pdf, ps, and svg), sometimes fallback -to using image-based rendering for some operations. In cairo 1.2.0 -these image fallbacks were scaled improperly. Applications using cairo -can influence the resolution of the image fallbacks with -cairo_surface_set_fallback_resolution. With the bug, any value other -than 72.0 would lead to incorrect results, (larger values would lead -to increasingly shrunken output). - -report: https://bugs.freedesktop.org/show_bug.cgi?id=7533 -fix: http://gitweb.freedesktop.org/?p=cairo;a=commit;h=1feb4291cf7813494355459bb547eec604c54ffb - -Fix inadvertent semantic change of font matrix translation (Behdad Esfahbod) ----------------------------------------------------------------------------- -The 1.2.0 release introduced an inadvertent change to how the -translation components of a font matrix are interpreted. In the 1.0 -series, font matrix translation could be used to offset the glyph -origin, (though glyph metrics were reported incorrectly in -1.0). However in 1.2.0, the translation was applied to the advance -values between each glyph. The 1.2.0 behavior is fairly useless in -practice, and it was not intentional to introduce a semantic -change. With 1.2.2 we return to the 1.0 semantics, with a much better -implementation that provides correct glyph metrics. - -fix: http://gitweb.freedesktop.org/?p=cairo;a=commit;h=84840e6bba6e72aa88fad7a0ee929e8955ba9051 - -Fix create_similar to preserve fallback resolution and font options (Behdad Esfahbod) -------------------------------------------------------------------------------------- -There has been a long-standing issue with cairo_surface_create_similar -such that font options and other settings from the original -destination surface would not be preserved to the intermediate -"similar" surface.

Congratulations to all contributors to cairo! - -Snapshot 1.1.10 (2006-06-16 Carl Worth <cworth@cworth.org>) -=========================================================== -This is the fifth in a series of snapshots working toward the 1.2 -release of cairo. - -The primary motivation for this snapshot is to fix a long-standing bug -that had long been silent, but as of the 1.1.8 snapshot started -causing crashes when run against 16-bit depth X servers, (often Xvnc -or Xnest). The fix for this adds a new CAIRO_FORMAT_RGB16_565 to the -API. - -This snapshot also includes a rewrite of cairo's SVG backend to -eliminate the dependency on libxml2. With this in place, cairo 1.2 -will not depend on any libraries that cairo 1.0 did not. - -As usual, there are also a few fixes for minor bugs. - -Snapshot 1.1.8 (2006-06-14 Carl Worth <cworth@cworth.org>) -========================================================== -This is the fourth in a series of snapshots working toward the 1.2 -release of cairo. At this point, all major features of the 1.2 release -are in place, leaving just a few bug fixes left. - -In particular, there well be no additional API changes between this -1.1.8 snapshot and the 1.2 release. - -The announcement for 1.1.6 mentioned several API changes being -considered. Only one of these changes was actually implemented -(set_dpi -> fallback_resolution). This change does introduce one -source-level incompatibility with respect to previous 1.1.x snapshots, -so see below for details. - -Here is an abbreviated summary of changes since the 1.1.6 snapshot: - -** API Change ** ----------------- -According to the plan mentioned in the 1.1.6 notes, one source-level -incompatible change has been implemented. The following three -functions have been removed from cairo's API: - - cairo_pdf_surface_set_dpi - cairo_ps_surface_set_dpi - cairo_svg_surface_set_dpi - -and in their place the following function has been added: - - cairo_surface_set_fallback_resolution - -The signature and semantics of the function remains the same, so it is -a simple matter of changing the name of the function when calling -it. As a transition mechanism, this snapshot will (on many systems) -build to include the old symbols so that code previously compiled will -still run. However, all source code using the old names must be -updated before it will compile. And the upcoming 1.2 release is not -anticipated to include the old symbols. - -Finally, it should be pointed out that the old symbols never existed -in the supported API of any stable release of cairo. (In the stable -1.0 releases the PDF, PS, and SVG backends were advertised as -experimental and unstable.) - -And, as always, cairo continues to maintain source and binary -compatibility between major releases. So applications compiled against -supported backends in a stable release of cairo (1.0.4 say) will -continue to compile and run without modification against new major -releases (1.2.0 say) without modification. - -API additions -------------- -The following new functions have been added to cairo's API: - - cairo_surface_get_content - cairo_debug_reset_static_data - cairo_image_surface_get_data - cairo_image_surface_get_format - cairo_image_surface_get_stride - cairo_win32_font_face_create_for_hfont - -New, backend-specific pkg-config files --------------------------------------- -In addition to the original cairo.pc file, cairo will also now install -a pkg-config files for each configured backend, (for example -cairo-pdf.pc, cairo-svg.pc, cairo-xlib.pc, cairo-win32.pc, etc.) this -also includes optional font backends (such as cairo-ft.pc) and the -optional png functionality (cairo-png.pc). - -These new pkg-config files should be very convenient for allowing -cairo-using code to easily check for the existing of optional -functionality in cairo without having to write complex rules to grub -through cairo header files or the compiled library looking for -symbols. - -Printing backend (PS, PDF, and SVG) ------------------------------------ -Improving the quality of the "printing" backends has been a priority -of the development between cairo 1.1.6 and cairo 1.1.8. - -The big improvement here is in the area of text output. Previously, at -best, text was output as paths without taking advantage of any font -support available in the output file format. - -Now, at the minimum text paths will be shared by using type3 fonts -(for PS and PDF---and similarly, defs for SVG). Also, if possible, -type3 and truetype fonts will be embedded in PostScript and PDF -output. There are still some known bugs with this, (for example, -selecting text in a cairo-generated PDF file with an embedded truetype -font does not work). So there will be some more changes in this area -before cairo 1.2, but do try test this feature out as it exists so -far. - -Many thanks to Kristian Høgsberg for the truetype and type1 font -embedding. - -win32 backend -------------- -Performance improvements by preferring GDI over pixman rendering when possible. -Fixes for text rendering. - -xlib backend ------------- -Fix potentially big performance bug by making xlib's create_similar -try harder to create a pixmap of a depth matching that of the screen. - -Bug fixes ---------- -Among various other fixes, the following bugs listed in bugzilla have -been fixed: - - Bug 2488: Patch to fix pixman samping location bug (#2488). - https://bugs.freedesktop.org/show_bug.cgi?id=2488 - - Bug 4196: undef MIN an MAX before defining to avoid duplicate definition - https://bugs.freedesktop.org/show_bug.cgi?id=4196 - - Bug 4723: configure.in: Fix m4 quoting when examining pkg-config version - https://bugs.freedesktop.org/show_bug.cgi?id=4723 - - Bug 4882: Flag Sun's X server has having buggy_repeat. - https://bugs.freedesktop.org/show_bug.cgi?id=4882 - - Bug 5306: test/pdf2png: Add missing include of stdio.h - https://bugs.freedesktop.org/show_bug.cgi?id=5306 - - Bug 7075: Fix make clean to remove cairo.def - https://bugs.freedesktop.org/show_bug.cgi?id=7075 - -(Many thanks to Behdad Esfahbod for helping us track down and fix many -of these.) - -Snapshot 1.1.6 (2006-05-04 Carl Worth <cworth@cworth.org>) -========================================================== -This is the third in a series of snapshots working toward the imminent -1.2 release of cairo. For a list of items still needing work on the -cairo 1.2 roadmap, please see: - - http://cairographics.org/ROADMAP - -As can be seen in that list, there are no longer any API additions -left on the roadmap. Instead, there is a feature (PDF type 3 fonts) a -performance optimization (X server gradients) and a list of bug -fixes. This gives us a fair amount of freedom to cut the 1.2 release -at almost any point by deciding to defer remaining bug fixes to -subsequent maintenance releases such as 1.2.2 and 1.2.4. - -Before we will do that, we must first be wiling to commit to all the -new API additions. As a heads-up, there are a couple of potential API -changes being considered. (Note that these are changes to new API -introduced during 1.1 so these will not introduce API -incompatibilities compared to the stable 1.0 series). The changes -being considered are: - - cairo_get_group_target: may acquire x and y offset return - parameters. May also be eliminated in favor of - cairo_get_target assuming its role - - cairo_pdf_surface_set_dpi: - cairo_ps_surface_set_dpi: - cairo_svg_surface_set_dpi: These functions may be removed in favor - of a new cairo_surface_set_fallback_resolution - -Additionally there is the possibility of a slight change in the -semantics of cairo_set_line_width. We believe the current behavior of the sequence: - - cairo_set_line_width; ... change CTM ...; cairo_stroke; - -is buggy. It is currently behaving the same as: - - ... change CTM ...; cairo_set_line_width; cairo_stroke; - -We are considering fixing this bug before 1.2 with the hope that -nobody is already relying on the buggy behavior described here. Do -shout if you suspect you might be in that position. - -The items included in this snapshot (since the 1.1.4 snapshot) are -described below. - -API additions -------------- -The long-awaited group-rendering support is now available with the -following function calls: - - cairo_push_group - cairo_push_group_with_content - cairo_pop_group - cairo_pop_group_to_source - cairo_get_group_target - -This API provides a much more convenient mechanism for doing rendering -to an intermediate surface without the need to manually create a -temporary cairo_surface_t and a temporary cairo_t and clean them up -afterwards. - -Add the following missing get function to complement -cairo_surface_set_device_offset: - - cairo_surface_get_device_offset - -PDF backend (API addition) --------------------------- -The PDF backend now provides for per-page size changes, (similar to -what the PostScript backend got in the 1.1.4 snapshot). The new API -is: - - cairo_pdf_surface_set_size - -Xlib backend (API additions) ----------------------------- -The following functions have been added to allow the extraction of -Xlib surface: - - cairo_xlib_surface_get_display - cairo_xlib_surface_get_drawable - cairo_xlib_surface_get_screen - cairo_xlib_surface_get_visual - cairo_xlib_surface_get_depth - -XCB backend (experimental) --------------------------- -Update backend so that it now compiles with the recent XCB 0.9 release. - -Bug fixes and memory leak cleanup ---------------------------------- -Various little things, nothing too significant though. - -Snapshot 1.1.4 (2006-05-03 Carl Worth <cworth@cworth.org>) -========================================================== -This is the second in a series of snapshots working toward the -upcoming 1.2 release of cairo. For a list of items still needing work -on the cairo 1.2 roadmap, please see: - - http://cairographics.org/ROADMAP - -The items included in this snapshot (since the 1.1.2 snapshot) are -described below. - -PostScript backend: new printing-oriented API ---------------------------------------------- -We anticipate that with cairo 1.2, toolkits will begin to use cairo -for printing on systems that use PostScript as the spool format. To -support this use case, we have added 4 new function calls that are -specific to the PostScript backend: - - cairo_ps_surface_set_size - cairo_ps_surface_dsc_comment - cairo_ps_surface_dsc_begin_setup - cairo_ps_surface_dsc_begin_page_setup - -These functions allow variation of the page size/orientation from one -page to the next in the PostScript output. They also allow the toolkit -to provide per-document and per-page printer control options in a -device-independent way, (for example, by using PPD options and -emitting them as DSC comments into the PostScript output). This should -allow toolkits to provide very fine-grained control of many options -available in printers, (media size, media type, tray selection, etc.). - -SVG backend: builds by default, version control ------------------------------------------------ -The SVG backend continues to see major improvements. It is expected -that the SVG backend will be a supported backend in the 1.2 -release. This backend will now be built by default if its dependencies -(freetype and libxml2) are met. - -Additionally, the SVG backend now has flexibility with regard to what -version of SVG it targets. It will target SVG 1.1 by default, which -will require image fallbacks for some of the "fancier" cairo -compositing operators. Or with the following new function calls: - - cairo_svg_surface_restrict_to_version - cairo_svg_get_versions - cairo_svg_version_to_string - -it can be made to target SVG 1.2 in which there is native support for -these compositing operators. - -Bug fixes ---------- -At least the following bugs have been fixed since the 1.1.2 snapshot: - -crash at XRenderAddGlyphs -https://bugs.freedesktop.org/show_bug.cgi?id=4705 - -Can't build cairo-1.1.2 on opensolaris due to " void function cannot return value" -https://bugs.freedesktop.org/show_bug.cgi?id=6792 - -Missing out-of-memory check at gfx/cairo/cairo/src/cairo-atsui-font.c:185 -https://bugzilla.mozilla.org/show_bug.cgi?id=336129 - -A couple of memory leaks. - -Snapshot 1.1.2 (2006-04-25 Carl Worth <cworth@cworth.org>) -========================================================== -This is the first in a series of snapshots working toward the upcoming -1.2 release of cairo. (Subsequent snapshot will use successive even -numbers for the third digit, 1.1.4, 1.1.6, etc.) This snapshot is -backwards-compatible with the 1.0 series---it makes a few API -additions but does not remove any API. - -PostScript and PDF backends are no longer "experimental" --------------------------------------------------------- -The major theme of the 1.2 release is improved PostScript and PDF -backends for cairo. Unlike the 1.0 series, in the 1.2 series these -backends will not be marked as experimental and will be enabled by -default. We encourage people to test this snapshot and the PS/PDF -backends in particular as much as possible. - -The PostScript and PDF output is not yet ideal. - - * One major problem with the PostScript output is that image - fallbacks are used more often than strictly necessary, and the - image fallbacks are at a lower resolution than desired, (the - cairo_ps_surface_set_dpi call is ignored). - - * The major drawback of the current PDF backend implementation is - its text support. Every glyph is represented by a filled path in - the PDF file. The causes file sizes to be much larger and - rendering to be much slower than desired. - -It is anticipated that both of these shortcomings will see some -improvements before the final 1.2 release. - -In spite of those shortcomings, we hope that the PS and PDF backends -will yield faithful results for pretty much any cairo operations you -can throw at them. Please let us know if you are getting obviously -"different" results from the PS/PDF backends than from the image or -xlib backends. - -Other new experimental backends -------------------------------- -This snapshot includes three new backends that did not exist in the -1.0 series: - - * beos backend - - * directfb backend - - * svg backend - -These are all currently marked "experimental" and are disabled by -default. But the SVG backend in particular has seen a lot of recent -development and is very close to passing the entire cairo test -suite. It is possible that this backend will become a fully supported -backend by the time of the cairo 1.2 release. - -Public API additions --------------------- -There have been a few new API functions added to cairo, including: - -New get_type functions for querying sub-types of object: - - cairo_surface_get_type - cairo_pattern_get_type - cairo_font_face_get_type - cairo_scaled_font_get_type - -More convenience in working with cairo_scaled_font_t with new getter -functions: - - cairo_scaled_font_get_font_face - cairo_scaled_font_get_font_matrix - cairo_scaled_font_get_ctm - cairo_scaled_font_get_font_options - -As well as a convenience function for setting a scaled font into a -cairo context: - - cairo_set_scaled_font - -and a function to allow text extents to be queried directly from a -scaled font, (without requiring a cairo_surface_t or a cairo_t): - - cairo_scaled_font_text_extents - -These new scaled font functions were motivated by the needs of the -pango library. - -Finally, a new path-construction function was added which clears the -current point in preparation for a new sub path. This makes cairo_arc -easier to use in some situations: - - cairo_new_sub_path - -Before the 1.2 release is final we do still plan a few more API -additions specifically motivated by the needs of Mozilla/Firefox. - -Optimizations and bug fixes ---------------------------- -Shortly after the 1.0 maintenance series branched off the mainline -there was a major rework of the cairo font internals. This should -provide some good performance benefits, but it's also another area -people should look at closely for potential regressions. - -There has not yet been any widespread, systematic optimization of -cairo, but various performance improvements have been made, (and some -of them are fairly significant). So if some things seem faster than -1.0 then things are good. If there are any performance regressions -compared to 1.0 then there is a real problem and we would like to hear -about that. - -There has been a huge number of bug fixes---too many to mention in -detail. Again, things should be better, and never worse compared to -1.0. Please let us know if your testing shows otherwise. - -Release 1.0.2 (2005-10-03 Carl Worth <cworth@cworth.org>) -========================================================= -For each bug number XXXX below, see: - - https://bugs.freedesktop.org/show_bug.cgi?id=XXXX - -for more details. - -General bug fixes ------------------ - * 4408 - Add support for dashing of stroked curves - (Carl Worth) - - * 4409 - Fix dashing so that each dash is capped on both ends - (Carl Worth) - - * 4414 - Prevent SIGILL failures (proper use of -mmmx and -msse flags) - (Sebastien Bacher, Billy Biggs) - - * 4299 - Fix crashes with text display in multi-threaded program - (Alexey Shabalin, Carl Worth) - - * 4401 - Do not use sincos function since it is buggy on some platforms) - (Tim Mooney, Carl Worth) - - * 4245 - Fix several bugs in the test suite exposed by amd64 systems - (Seemant Kulleen, Carl Worth) - - * 4321 - Add missing byteswapping on GetImage/PutImage - (Sjoerd Simons, Owen Taylor) - - * 4220 - Make the check for rectangular trapezoids simpler and more accurate - (Richard Stellingwerff, Owen Taylor) - - * 4260 - Add missing channel-order swapping for antialised fonts - (Barbie LeVile, Owen Taylor) - - * 4283 - Fix compilation failure with aggressive inlining (gcc -O3) - (Marco Manfredini, Owen Taylor) - - * 4208 - Fix some warnings from sparse - (Kjartan Maraas, Billy Biggs) - - * 4269 - Fix to not crash when compiled with -fomit-frame-pointer - (Ronald Wahl, Owen Taylor) - - * 4263 - Improve performance for vertical gradients - (Richard Stellingwerff, Owen Taylor) - - * 4231 - * 4298 - Accomodate gentoo and Mandriva versions in X server vendor string check - (Billy Biggs, Frederic Crozat, Owen Taylor) - -win32-specific fixes --------------------- - * 4599 - Fix "missing wedges" on some stroked paths (win32) - (Tim Rowley, Jonathan Watt, Bertram Felgenhauer, Carl Worth, Keith Packard) - - * 4612 - Fix disappearing text if first character out of surface (win32) - (Tim Rowley) - - * 4602 - Fix shutdown of cairo from failing intermediate, size-0 bitmaps (win32) - Aka. the "white rectangles" bug from mozilla-svg testing - (Tim Rowley) - - * Various portability improvements for win32 - (Hans Breuer, Owen Taylor, Carl Worth) - - * 4593 - Fix font sizes to match user expectations (win32) - (Tor Lillqvist, Owen Taylor) - - * 3927 - Fix to report metrics of size 0 for glyph-not-available (win32) - (Hans Breuer, Owen Taylor, Tor Lillqvist) - - * Add locking primitives for win32 - (Hans Breuer) - -xlib-specific fixes -------------------- - * Fix crash from size-0 pixmap due to empty clip region (xlib) - (Radek DoulÃk, Carl Worth) - -Release 1.0.0 (2005-08-24 Carl Worth <cworth@cworth.org>) -========================================================= -Experimental backends ---------------------- - * The Glitz, PS, PDF, Quartz, and XCB backends have been declared - experimental, and are not part of the API guarantees that accompany - this release. They are not built by default, even when the required - libraries are available, and must be enabled explicitly with - --enable-ps, --enable-pdf, --enable-quartz or --enable-xcb. - - It is very painful for us to be pushing out a major release without - these backends enabled. There has been a tremendous amount of work - put into each one and all are quite functional to some - extent. However, each also has some limitations. And none of these - backends have been tested to the level of completeness and - correctness that we expect from cairo backends. - - We do encourage people to experiment with these backends and report - success, failure, or means of improving them. - -Operator behavior ------------------ - * Prior to 0.9.0 the SOURCE, CLEAR and a number of other operators - behaved in an inconsistent and buggy fashion and could affect areas - outside the clip mask. In 0.9.0, these six "unbounded" operators - were fixed to consistently clear areas outside the shape but within - the clip mask. This is useful behavior for an operator such as IN, - but not what was expected for SOURCE and CLEAR. So, in this release - the behavior of SOURCE and CLEAR has been changed again. They now - affect areas only within both the source and shape. We can write - the new operators as: - - SOURCE: dest' = (mask IN clip) ? source : dest - CLEAR: dest' = (mask IN clip) ? 0 : dest - -Behavior and API changes ------------------------- - * Setting the filter on a gradient pattern would change the - interpolation between color stops away from the normal linear - interpolation. This dubious behavior has been removed. - - * The CAIRO_CONTENT_VALID() and CAIRO_FORMAT_VALID() macros -- - implementation details that leaked into cairo.h -- have been moved - into an internal header. - - * The cairo_show_text function now advances the current point - according to the total advance values of the string. - -API additions -------------- - * cairo_set_dash can now detect error and can set - CAIRO_STATUS_INVALID_DASH. - -Features --------- - * When compiled against recent versions of fontconfig and FreeType, - artificial bold fonts can now be turned on from fonts.conf using - the FC_EMBOLDEN fontconfig key. - -Optimization ------------- - * The compositing code from the 'xserver' code tree has now been - completely merged into libpixman. This includes MMX optimization of - common operations. - - * The image transformation code in libpixman has been improved and - now performs significantly faster. - -Bug fixes ---------- - * Several crashes related to corruption in the font caches have been - fixed. - - * All test cases now match pixel-for-pixel on x86 and PPC; this - required fixing bugs in the compositing, stroking, and pattern - rendering code. - - * Negative dash offsets have been fixed to work correctly. - - * The stroking of paths with mutiple subpaths has now been fixed to - apply caps to all subpaths rather than just the last one. - - * Many build fixes for better portability on various systems. - - * Lots of other bug fixes, but we're too tired to describe them in - more detail here. - -Release 0.9.2 (2005-08-13 Carl Worth <cworth@cworth.org>) -========================================================= -Release numbering ------------------ - * You will notice that this release jumped from 0.9.0 to 0.9.2. We've - decided to use an odd micro version number (eg. 0.9.1) to indicate - in-progress development between releases. As soon as 0.9.2 is - tagged, the version will be incremented in CVS to 0.9.3 where it - will stay until just before 0.9.4 is built, uploaded, and tagged. - - So, even-micro == a released version, odd-micro == something in-between. - -Libpixman dependency dropped ----------------------------- - * As of this release, the dependency on an external libpixman has - been dropped. Instead, the code from libpixman needed for cairo has - been incorporated into the cairo source tree. The motivation for - this change is that while cairo's API is stable and ready to be - maintained after the 1.0 release, libpixman's API is not, so we do - not want to expose it at this time. - - Also, the incorporation of libpixman into cairo also renames all - previously-public libpixman symbols in order to avoid any conflict - with a future release of libpixman - -API additions -------------- - * Macros and functions have been added so that the version of cairo - can be queried at either compile-time or at run-time. The version - is made available as both a human-readable string and as a single - integer: - - CAIRO_VERSION_STRING eg. "0.9.2" - CAIRO_VERSION eg. 000902 - - const char* - cairo_version_string (void); /* eg. "0.9.2" */ - - int - cairo_version (void); /* eg. 000902 */ - - A macro is provided to convert a three-part component version into - the encoded single-integer form: - - CAIRO_VERSION_ENCODE(X,Y,Z) - - For example, the CAIRO_VERSION value of 000902 is obtained as - CAIRO_VERSION_ENCODE(0,9,2). The intent is to make version - comparisons easy, either at compile-time: - - #if CAIRO_VERSION >= CAIRO_VERSION_ENCODE(0,9,2) - ... - #endif - - Or at run-time: - - if (cairo_version() >= CAIRO_VERSION_ENCODE(0,9,2)) { /* ... */ } - -Thread safety -------------- - * This release adds pthread-based locking (when available) to make - the caches used by cairo safe for threaded programs. Some may - remember a failed experiment with this locking between the 0.5.1 - and 0.5.2 snapshots, (where even single-threaded programs that - linked with -lpthread would deadlock). We believe that that problem - has been fixed, so we are looking forward to testing and reports - from users with threaded applications. - -Bug fixes ---------- - * The XCB and Quartz backends failed to compiled in the 0.9.0 release - due to minor syntax errors. These have now been fixed. - - * Various crashes in glitz and pixman due to size 0 glyphs have been - fixed. - -Release 0.9.0 (2005-08-08 Carl Worth <cworth@cworth.org>) -========================================================= -Soname change -------------- - * In all prior snapshots, the libtool library versioning was set to - 1:0:0. As this release is intended to mark the beginning of - backwards-compatible releases, the versioning has been incremented - to 2:0:0. You will notice that the numeric extension on the - installed library filename will change similarly. - - This change will also require all cairo-using applications to be - recompiled. We recognize that this may cause some frustration since - this release is backwards-compatible with 0.6.0 and in that sense - "shouldn't" require re-compilation. However, since all historical - snapshots have used the same 1:0:0 version in spite of incompatible - API changes between them, it was essential that the upcoming 1.0 - release series have distinct library versioning. - - All future releases will use the library versioning to properly - indicate compatibility between releases. So, any application - re-compiled now to work with the 0.9.0 will not need to be - recompiled when a compatible 1.0 release of cairo is made in the - future. - -API additions -------------- - * Add new function calls to set/get the current antialiasing mode in - the graphics state: - - cairo_set_antialias - cairo_get_antialias - - This call accepts the same modes recently added for font options - (NONE or GRAY) but affects the rendering of geometry other than - text. The intent of this call is to enable more precise control of - which pixels are affected by each operation, for example to allow - for full-scene antialiasing for seam-free rendering. It is not - expected that non-antialiased rendering will perform better than - anti-aliased rendering. - - * Three new functions were added to provide support for mixed cairo- - and non-cairo drawing to the same surface: - - cairo_surface_mark_dirty - cairo_surface_mark_dirty_rectangle - cairo_surface_flush - - * The return type of the several "reference" functions was change, - (API compatibly), from void to the same type as the argument. The - affected functions are: - - cairo_font_face_reference - cairo_scaled_font_reference - cairo_pattern_reference - cairo_surface_reference - cairo_reference - - This allows a convenient way to assign and reference in a single - statement. - -Semantic changes ----------------- - * The behavior of cairo_set_source with a pattern with a non-identity - matrix was previously not well-defined. The new behavior is as - follows: - - The pattern's transformation matrix will be locked to the - user space in effect at the time of cairo_set_source(). This means - that further modifications of the CTM will not affect the source - pattern. - -cairo-win32 ------------ - * Some portability improvements, (eg. workaround for missing stdint.h). - -cairo-ft --------- - * Updated to allow compilation with older versions of freetype. - -Bug fixes ---------- - * Fix the unbounded operators to actually produce a correct result, - (previously the results were artificially restricted to the - bounding box of whatever shape was being drawn rather than - extending out infinitely). The fixed operators are: - - CAIRO_OPERATOR_CLEAR - CAIRO_OPERATOR_SOURCE - CAIRO_OPERATOR_OUT - CAIRO_OPERATOR_IN - CAIRO_OPERATOR_DEST_IN - CAIRO_OPERATOR_DEST_ATOP - - * Fix cairo_mask and cairo_mask_surface to transform the mask by the - current transformation matrix (CTM). - - * Fix cairo_set_source to lock the CTM used to transform the pattern. - - * Workaround for X server Render bug involving repeating patterns - with a general transformation matrix. - - * cairo_get_font_face fixed to return a "nil" font face object rather - than NULL on error. - - * cairo_set_font_face fixed to not crash if given a NULL font face, - (which is the documented interface for restoring the default font - face). - - * Fix xlib glyphset caching to not try to free a NULL glyph. - -Snapshot 0.6.0 (2005-07-28 Carl Worth <cworth@cworth.org>) -========================================================== -API changes ------------ -* The prototypes of the following functions have changed: - - cairo_xlib_surface_create_with_xrender_format - cairo_xlib_surface_create_for_bitmap - - A Screen* parameter has been added to each. This allows the cairo - xlib backend to work correctly with multi-head X servers. - -* The following function has been modified: - - cairo_scaled_font_create - - to accept a cairo_font_options_t*. See below fore more details. - -* All opaque, reference-counted cairo objects have now been moved to a - standard error-handling scheme. The new objects to receive this - treatment are cairo_font_face_t, cairo_scaled_font_t, and - cairo_surface_t. (Previous snapshots already provided this scheme - for cairo_t, cairo_path_t, and cairo_pattern_t.) - - This changes two functions to have a return type of void rather than - cairo_status_t: - - cairo_scaled_font_extent - cairo_surface_finish - - And significantly, none of the create functions for any of the - objects listed above will return NULL. The pointer returned from any - function will now always be a valid pointer and should always be - passed to the corresponding destroy function when finished - - The simplest strategy for porting code is to switch from: - - object = cairo_<object>_create (); - if (object == NULL) - goto BAILOUT; - - /* act on object */ - - cairo_<object>_destroy (object); - - to: - - object = cairo_<object>_create (); - if (cairo_<object>_status (object)) - goto BAILOUT; - - /* act on object */ - - cairo_<object>_destroy (object); - - But significantly, it is not required to check for an error status - before the "act on object" portions of the code above. All - operations on an object with an error status are, by definition, - no-ops without side effect. So new code might be written in an - easier-to-read style of: - - object = cairo_<object>_create (); - - /* act on object */ - - cairo_<object>_destroy (object); - - with cairo_<object>_status checks placed only at strategic - locations. For example, passing an error object to another object, - (eg. cairo_set_source with an in-error pattern), will propagate the - error to the subsequent object (eg. the cairo_t). This means that - error checking can often be deferred even beyond the destruction of - a temporary object. - -API additions -------------- -* New functions for checking the status of objects that have been - switched to the common error-handling scheme: - - cairo_font_face_status - cairo_scaled_font_status - cairo_surface_status - -* The _cairo_error function which was added in 0.5.1 has now been made - much more useful. In 0.5.1 only errors on cairo_t objects passed - through _cairo_error. Now, an error on any object should pass - through _cairo_error making it much more reliable as a debugging - mechanism for finding when an error first occurs. - -* Added new font options support with a myriad of functions: - - cairo_font_options_create - cairo_font_options_copy - cairo_font_options_destroy - - cairo_font_options_status - - cairo_font_options_merge - cairo_font_options_equal - cairo_font_options_hash - - cairo_font_options_set_antialias - cairo_font_options_get_antialias - cairo_font_options_set_subpixel_order - cairo_font_options_get_subpixel_order - cairo_font_options_set_hint_style - cairo_font_options_get_hint_style - cairo_font_options_set_hint_metrics - cairo_font_options_get_hint_metrics - - cairo_surface_get_font_options - - cairo_ft_font_options_substitute - - cairo_set_font_options - cairo_get_font_options - - This new font options support allows the application to have much - more fine-grained control over how fonts are rendered. - Significantly, it also allows surface backends to have some - influence over the process. For example, the xlib backend now - queries existing Xft properties to set font option defaults. - -* New function: - - cairo_xlib_surface_set_drawable - - which allows the target drawable for an xlib cairo_surface_t to be - changed to another with the same format, screen, and display. This - is necessary in certain double-buffering techniques. - -New features ------------- -* Sub-pixel text antialiasing is now supported. - -Bug fixes ---------- -* Fixed assertion failure in cairo_surface_create_similar when - application commits an error by passing a cairo_format_t rather than - a cairo_content_t. - -* Avoid division by zero in various places (cairo-ft). - -* Fix infinite loop when using non-default visuals (cairo-xlib). - -* Eliminate segfault in cairo_image_surface_create_from_png_stream. - -* Prevent errant sign-extension of masks on 64-bit architectures - (cairo-xlib and cairo-xcb). - -* Other miscellaneous fixes. - -Snapshot 0.5.2 (2005-07-18 Carl Worth <cworth@cworth.org>) -========================================================== -API changes ------------ -* New functions for creating patterns of a single color: - - cairo_pattern_create_rgb - cairo_pattern_create_rgba - -* Change cairo_surface_create_similar to accept a new type of - cairo_content_t rather than cairo_format_t: - - typedef enum _cairo_content { - CAIRO_CONTENT_COLOR = 0x1000, - CAIRO_CONTENT_ALPHA = 0x2000, - CAIRO_CONTENT_COLOR_ALPHA = 0x3000 - } cairo_content_t; - -* Add new CAIRO_FORMAT_VALID and CAIRO_CONTENT_VALID macros. - -* Remove unused status value: - - CAIRO_STATUS_NO_TARGET_SURFACE - -* Add new status values: - - CAIRO_STATUS_INVALID_STATUS - -* Require libpixman >= 0.1.5 (for necessary bug fixes) - -Bug fixes ---------- -* Fix cairo_surface_write_to_png for RGB24 images. - -* Fix broken metrics and rendering for bitmap fonts. Add mostly - useless bitmap glyph transformation. - -* Fix glyph caches to not eject entries that might be immediately - needed, (fixing intermittent crashes when rendering text). - -* Fix all memory leaks found by running "make check-valgrind". - -ATSUI backend changes ---------------------- -* Allow building against < 10.3 SDK. - -* Prevent crash on empty strings. - -Glitz backend changes ---------------------- -* Require glitz >= 0.4.4. - -* Use frame buffer objects instead of pbuffers for accelerated - offscreen drawing. - -* Minor improvement to gradient pattern creation. - -PostScript backend fixes ------------------------- -* Rewrite of the PS backend to generate more interesting output that - the old big-image implementation. - -Win32 backend fixes -------------------- -* Implement glyph path support. - -* Fix swap of blue and green values in the fill_rectangles path. - -Xlib backend fixes ------------------- -* Add optimization to use XCopyArea rather than XRenderComposite when - transforming only with an integer translation, and using SOURCE - operator or OVER with a source pattern without alpha. - -Snapshot 0.5.1 (2005-06-20 Carl Worth <cworth@cworth.org>) -========================================================== -API changes ------------ -* Removed cairo_status_string(cairo_t*) and add - cairo_status_to_string(cairo_status_t) in its place. Code using - cairo_status_string can be ported forward as follows: - - cairo_status (cr); - -> - cairo_status_to_string (cairo_status (cr)); - -* Removed the BAD_NESTING restriction which means that two different - cairo_t objects can now interleave drawing to the same - cairo_surface_t without causing an error. - -* The following functions which previously had a return type of - cairo_status_t now have a return type of void: - - cairo_pattern_add_color_stop_rgba - cairo_pattern_set_matrix - cairo_pattern_get_matrix - cairo_pattern_set_extend - cairo_pattern_set_filter - - See discussion of cairo_pattern_status below for more details. - -API additions -------------- -* Improved error handling: - - cairo_status_t - cairo_pattern_status (cairo_pattern_t *pattern); - - This snapshot expands the status-based error handling scheme from - cairo_t to cairo_path_t and cairo_pattern_t. It also expands the - scheme so that object-creating functions, (cairo_create, - cairo_pattern_create_*, cairo_copy_path_*), are now guaranteed to - not return NULL. Instead, in the case of out-of-memory these - functions will return a static object with - status==CAIRO_STATUS_NO_MEMORY. The status can be checked with the - functions cairo_status and cairo_pattern_status, or by direct - inspection of the new status field in cairo_path_t. - - Please note that some objects, including cairo_surface_t and all of - the font-related objects have not been converted to this - error-handling scheme. - -* In addition to the above changes, a new private function has been added: - - _cairo_error - - This function can be used to set a breakpoint in a debugger to make - it easier to find programming error in cairo-using code. (Currently, - _cairo_error is called when any error is detected within a cairo_t - context, but is not called for non-cairo_t errors such as for - cairo_path_t and cairo_pattern_t). - -* Fixed cairo_path_data_t so that its enum is visible to C++ code, (as - cairo_path_data_type_t). - -Performance improvements ------------------------- -* Made a minor performance improvement for clipping, (restrict clip - surface to the new intersected bounds). - -* Optimize rendering of a solid source pattern with a pixel-aligned - rectangular path to use backend clipping rather than rasterization - and backend compositing. - -* Optimize cairo_paint_with_alpha to defer to cairo_paint when alpha - is 1.0. - -Bug fixes ---------- -* Fixed memory leak in cairo_copy_path. - -* A build fix for non-srcdir builds. - -PDF backend fixes ------------------ -* New support for path-based clipping. - -* Fix for text rotated to angles other than multiples of Ï€/2. - -Win32 backend fixes -------------------- -* Fix for text extents. - -Xlib backend ------------- -* Implemented a complex workaround for X server bug[*] related to - Render-based compositing with untransformed, repeating source - pictures. The workaround uses core Xlib when possible for - performance, (ie. with CAIRO_OPERATOR_SOURCE or CAIRO_OPERATOR_OVER - with an opaque source surface), and falls back to the pixman - image-based compositing otherwise. - - [*] https://bugs.freedesktop.org/show_bug.cgi?id=3566 - -* Various bug fixes, particularly in the fallback paths. - -Snapshot 0.5.0 (2005-05-17 Carl Worth <cworth@cworth.org>) -========================================================== -This is a pretty big, and fairly significant snapshot. It represents -between 2 and 3 months of solid work from a lot of people on improving -the API as much as possible. I'd like to express my appreciation and -congratulations to everyone who has worked on the big API Shakeup, -(whether in email battles over names, or fixing my silly bugs). - -This snapshot will require some effort on the part of users, since -there are a _lot_ of API changes (ie. no cairo program ever written is -safe --- they're all broken now in at least one way). But, in spite of -that, we do encourage everyone to move their code to this snapshot as -soon as possible. And we're doing everything we can think of to make -the transition as smooth as possible. - -The idea behind 0.5 is that we've tried to make every good API change -we could want now, and get them all done with. That is, between now -and the 1.0 release of cairo, we expect very few new API changes, -(though some will certainly sneak in). We will have some significant -additions, but the pain of moving code from cairo 0.4 to cairo 0.5 -should be a one time experience, and things should be much smoother as -we continue to move toward cairo 1.0. - -And with so many changes coming out for the first time in this 0.5 -release, we really do need a lot of people trying this out to make -sure the ideas are solid before we freeze the API in preparation for -the 1.0 release. - -OK, enough introduction. Here is a (not-quite-complete) description of -the API removals, changes and additions in this snapshot, (compared to -0.4.0) - -API removals -============ -The following public functions have been removed: - -- cairo_set_target_* - - This is a big change. See the description of cairo_create in - the API changes section for how to deal with this. - -- cairo_set_alpha - - Alpha blending hasn't gone away; there's just a much more - unified rendering model now. Almost all uses of - cairo_set_alpha will be trivially replaced with - cairo_set_source_rgba and a few others will be replaced just - as easily with cairo_paint_with_alpha. - -- cairo_show_surface - - Another useful function that we realized was muddling up the - rendering model. The replacement is quite easy: - cairo_set_source_surface and cairo_paint. - -- cairo_matrix_create -- cairo_matrix_destroy -- cairo_matrix_copy -- cairo_matrix_get_affine - - These functions supported an opaque cairo_matrix_t. We now - have an exposed cairo_matrix_t structure, so these can be - dropped. - -- cairo_surface_set_repeat -- cairo_surface_set_matrix -- cairo_surface_set_filter - - These properties don't belong on surfaces. If you were using - them, you'll just want to instead use - cairo_pattern_create_for_surface and then set these properties - on the pattern. - -- cairo_copy - - This was a confusing function and hopefully nobody will miss - it. But if you really don't find cairo_save/restore adequate, - let us know and we have another idea for a potential - replacement. - -And while we're on the subject of removals, we carefully tightened up -the cairo header files so they no longer gratuitously include header -files that are not strictly necessary, (stdio.h, stdint.h, pixman.h, -Xrender.h, etc. and their dependencies). This may lead to some -surprising errors, so keep your eyes open for that. - -API changes -=========== -Here are some of the API changes that have occurred: - -~ cairo_create(void) -> cairo_create(cairo_surface_t *) - - This is the big change that breaks every program. The ability - to re-target a cairo_t was not particularly useful, but it did - introduce a lot of muddy semantic questions. To eliminate - that, cairo_create now requires its target surface to be - passed in at creation time. This isn't too hard to cope with - as the typical first operation after cairo_create was often - cairo_set_target_foo. So the order of those two swap and the - application instead has cairo_foo_surface_create, then - cairo_create. - -~ cairo_current_* -> cairo_get_* - - We had a strange mixture of cairo_get and cairo_current - functions. They've all been standardized on cairo_get, (though - note one is cairo_get_current_point). - -~ CAIRO_OPERATOR_SRC -> CAIRO_OPERATOR_SOURCE -~ CAIRO_OPERATOR_OVER_REVERSE -> CAIRO_OPERATOR_DEST_OVER - - Many of the cairo_operator_t symbolic values were renamed to - reduce the amount of abbreviation. The confusing "OP_REVERSE" - naming was also changed to use "DEST_OP" instead which is - easier to read and has wider acceptance in other - libraries/languages. - -~ cairo_set_pattern -> cairo_set_source -~ cairo_set_rgb_color -> cairo_set_source_rgb - - All of the various functions that changed the source - color/pattern were unified to use cairo_set_source names to - make the relation more clear. - -~ cairo_transform_point -> cairo_user_to_device -~ cairo_transform_distance -> cairo_user_to_device_distance -~ cairo_inverse_transform_point -> cairo_device_to_user -~ cairo_inverse_transform_distance -> cairo_device_to_user_distance - - These names just seemed a lot more clear. - -~ cairo_init_clip -> cairo_reset_clip -~ cairo_concat_matrix -> cairo_transform - - More abbreviation elimination - -~ cairo_current_path -> cairo_copy_path -~ cairo_current_path_flat -> cairo_copy_path_flat - - The former mechanism for examining the current path was a - function that required 3 or 4 callbacks. This was more - complexity than warranted in most situations. The new - cairo_copy_path function copies the current path into an - exposed data structure, and the documentation provides a - convenient idiom for navigating the path data. - -API additions -------------- -+ cairo_paint - - A generalized version of the painting operators cairo_stroke - and cairo_fill. The cairo_paint call applies the source paint - everywhere within the current clip region. Very useful for - clearing a surface to a solid color, or painting an image, - (see cairo_set_source_surface). - -+ cairo_paint_with_alpha - - Like cairo_paint but applying some alpha to the source, - (making the source paint translucent, eg. to blend an image on - top of another). - -+ cairo_mask - - A more generalized version of cairo_paint_with_alpha which - allows a pattern to specify the amount of translucence at each - point rather than using a constant value everywhere. - -+ cairo_mask_surface - - A convenience function on cairo_mask for when the mask pattern - is already contained within a surface. - -+ cairo_surface_set_user_data -+ cairo_surface_get_user_data -+ cairo_font_face_set_user_data -+ cairo_font_face_get_user_data - - Associate arbitrary data with a surface or font face for later - retrieval. Get notified when a surface or font face object is - destroyed. - -+ cairo_surface_finish - - Allows the user to instruct cairo to finish all of its - operations for a given surface. This provides a safe point for - doing things such as flushing and closing files that the - surface may have had open for writing. - -+ cairo_fill_preserve -+ cairo_stroke_preserve -+ cairo_clip_preserve - - One interesting change in cairo is that the path is no longer - part of the graphics state managed by - cairo_save/restore. This allows functions to construct paths - without interfering with the graphics state. But it prevents - the traditional idiom for fill-and-stroke: - - cairo_save; cairo_fill; cairo_restore; cairo_stroke - - Instead we know have alternate versions cairo cairo_fill, - cairo_stroke, and cairo_clip that preserve the current path - rather than consuming it. So the idiom now becomes simply: - - cairo_fill_preserve; cairo_stroke - -+ cairo_surface_write_to_png -+ cairo_surface_write_to_png_stream - - In place of a single PNG backend, now a surface created - through any backend (except PDF currently) can be written out - to a PNG image. - -+ cairo_image_surface_create_from_png -+ cairo_image_surface_create_from_png_stream - - And its just as easy to load a PNG image into a surface as well. - -+ cairo_append_path - - With the new, exposed path data structure, it's now possible - to append bulk path data to the current path, (rather than - issuing a long sequence of cairo_move_to/line_to/curve_to - function calls). - -Xlib and XCB backends ---------------------- - -Any cairo_format_t and Colormap arguments have been dropped from -cairo_xlib_surface_create. There are also two new -cairo_xlib|xcb_surface_create functions: - - cairo_xlib|xcb_surface_create_for_bitmap - (Particular for creating A1 surfaces) - cairo_xlib|xcb_surface_create_with_xrender_format - (For any other surface types, not described by a Visual*) - -All of these surface create functions now accept width and height. In -addition, there are new cairo_xlib|xcb_surface_set_size functions -which must be called each time a window that is underlying a surface -changes size. - -Print backends (PS and PDF) ---------------------------- -The old FILE* based interfaces have been eliminated. In their place we -have two different functions. One accepts a simple const char -*filename. The other is a more general function which accepts a -callback write function and a void* closure. This should allow the -flexibility needed to hook up with various stream object in many -languages. - -In addition, when specifying the surface size during construction, the -units are now device-space units (ie. points) rather than inches. This -provides consistency with all the other surface types and also makes -it much easier to reason about the size of the surface when drawing to -it with the default identity matrix. - -Finally, the DPI parameters, which are only needed to control the -quality of fallbacks, have been made optional. Nothing is required -during surface_create (300 DPI is assumed) and -cairo_ps|pdf_surface_set_dpi can be used to set alternate values if -needed. - -Font system ------------ -Owen very graciously listened to feedback after the big font rework he -had done for 0.4, and came up with way to improve it even more. In 0.4 -there was a cairo_font_t that was always pre-scaled. Now, there is an -unscaled cairo_font_face_t which is easier to construct, (eg. no -scaling matrix required) and work with, (it can be scaled and -transformed after being set on the graphics state). And the font size -manipulation functions are much easier. You can set an explicit size -and read/modify/write the font matrix with: - - cairo_set_font_size - cairo_get_font_matrix - cairo_set_font_matrix - -(Previously you could only multiply in a scale factor or a matrix.) A -pleasant side effect is that we can (and do) now have a default font -size that is reasonable, as opposed to the old default height of one -device-space unit which was useless until scaled. - -Of course, the old pre-scaled font had allowed some performance -benefits when getting many metrics for a font. Those benefits are -still made available through the new cairo_scaled_font_t. And a -cairo_font_face_t can be "promoted" to a cairo_scaled_font_t by -suppling a font_matrix and the desired CTM. - -Quartz backend --------------- -Tim Rowley put in the work to bring the Quartz backend back after it -had been disabled in the 0.4.0 snapshot. He was not able to bring back -the function that allows one to create a cairo_font_t from an ATSUI -style: - - cairo_font_t * - cairo_atsui_font_create (ATSUStyle style); - -because he didn't have a test case for it. If you care about this -function, please provide a fairly minimal test and we'll try to bring -it back in an upcoming snapshot. - -Snapshot 0.4.0 (2005-03-08 Carl Worth <cworth@cworth.org>) -========================================================== -New documentation ------------------ -Owen Taylor has converted cairo's documentation system to gtk-doc and -has begun some long-needed work on the documentation, which can now be -viewed online here: - - http://cairographics.org/manual/ - -New backend: win32 ------------------- -This is the first snapshot to include a functional win32 backend, -(thanks to Owen Taylor). The interface is as follows: - - #include <cairo-win32.h> - - void - cairo_set_target_win32 (cairo_t *cr, - HDC hdc); - - cairo_surface_t * - cairo_win32_surface_create (HDC hdc); - - cairo_font_t * - cairo_win32_font_create_for_logfontw (LOGFONTW *logfont, - cairo_matrix_t *scale); - - cairo_status_t - cairo_win32_font_select_font (cairo_font_t *font, - HDC hdc); - - void - cairo_win32_font_done_font (cairo_font_t *font); - - double - cairo_win32_font_get_scale_factor (cairo_font_t *font); - -And see also the documentation at: - -http://cairographics.org/manual/cairo-Microsoft-Windows-Backend.html - -Disabled backend: quartz ------------------------- -Unfortunately, the quartz backend code is currently out of date with -respect to some recent backend interface changes. So, the quartz -backend is disabled in this snapshot. - -If the quartz backend is brought up-to-date before the next snapshot, -we would be glad to make a 0.4.1 snapshot that re-enables it, (we do -not expect many more big backend interface changes). - -API Changes ------------ -The font system has been revamped, (as Owen Taylor's work with -integrating pango and cairo gave us the first serious usage of the -non-toy font API). - -One fundamental, user-visible change is that the cairo_font_t object -now represents a font that is scaled to a particular device -resolution. Further changes are described below. - - cairo.h - ------- - Removed cairo_font_set_transform and cairo_font_current_transform. - - Added cairo_font_extents and cairo_font_glyph_extents. See - documentation for details: - - http://cairographics.org/manual/cairo-cairo-t.html#cairo-font-extents - - cairo-ft.h - ---------- - The cairo_ft_font API changed considerably. Please see the - documentation for details: - - http://cairographics.org/manual/cairo-FreeType-Fonts.html - -Performance ------------ -Make the fast-path clipping (pixel-aligned rectangles) faster. - -Add optimization for applying a constant alpha to a pattern. - -Optimize gradients that are horizontal or vertical in device space. - -Xlib: When RENDER is not available, use image surfaces for -intermediate surfaces rather than xlib surfaces. - -Backend-specific changes ------------------------- - Glitz - ----- - Major update to glitz backend. The output quality should now be just - as good as the image and xlib backends. - - Track changes to glitz 0.4.0. - - PDF - --- - Various improvements to produce more conformant output. - -Internals ---------- -David Reveman contributed a large re-work of the cairo_pattern_t -implementation, providing cleaner code and more optimization -opportunities. - - Backend interface changes - ------------------------- - Rework backend interface to accept patterns, not surfaces for source - and mask. - - Remove set_matrix, set_filter, and set_repeat functions. - - More sophisticated backend interface for image fallbacks, - ({acquire,release}_{source,dest}_image() and clone_similar). - -Bug fixes ---------- -Only install header files for backends that have been compiled. - -Fixed some rounding errors leading to incorrectly placed glyphs. - -Many other minor fixes. - -Snapshot 0.3.0 (2005-01-21 Carl Worth <cworth@cworth.org>) -========================================================== -Major API changes ------------------ -1) The public header files will no longer be directly installed into - the system include directory. They will now be installed in a - subdirectory named "cairo", (eg. in /usr/include/cairo rather than - in /usr/include). - - As always, the easiest way for applications to discover the - location of the header file is to let pkg-config generate the - necessary -I CFLAGS and -L/-l LDFLAGS. For example: - - cc `pkg-config --cflags --libs cairo` -o foo foo.c - - IMPORTANT: Users with old versions of cairo installed will need to - manually remove cairo.h and cairo-features.h from the - system include directories in order to prevent the old - headers from being used in preference to the new ones. - -2) The backend-specific portions of the old monolithic cairo.h have - been split out into individual public header files. The new files - are: - - cairo-atsui.h - cairo-ft.h - cairo-glitz.h - cairo-pdf.h - cairo-png.h - cairo-ps.h - cairo-quartz.h - cairo-xcb.h - cairo-xlib.h - - Applications will need to be modified to explicitly include the new - header files where appropriate. - -3) There are two new graphics backends in this snapshot, a PDF - backend, and a Quartz backend. There is also one new font backend, - ATSUI. - -PDF backend ------------ -Kristian Høgsberg has contributed a new backend to allow cairo-based -applications to generate PDF output. The interface for creating a PDF -surface is similar to that of the PS backend, as can be seen in -cairo-pdf.h: - - void - cairo_set_target_pdf (cairo_t *cr, - FILE *file, - double width_inches, - double height_inches, - double x_pixels_per_inch, - double y_pixels_per_inch); - - cairo_surface_t * - cairo_pdf_surface_create (FILE *file, - double width_inches, - double height_inches, - double x_pixels_per_inch, - double y_pixels_per_inch); - -Once a PDF surface has been created, applications can draw to it as -any other cairo surface. - -This code is still a bit rough around the edges, and does not yet -support clipping, surface patterns, or transparent gradients. Text -only works with TrueType fonts at this point and only black text is -supported. Also, the size of the generated PDF files is currently -quite big. - -Kristian is still actively developing this backend, so watch this -space for future progress. - -Quartz backend --------------- -Calum Robinson has contributed a new backend to allow cairo -applications to target native Mac OS X windows through the Quartz -API. Geoff Norton integrated this backend into the current -configure-based build system, while Calum also provided Xcode build -support in the separate "macosx" module available in CVS. - -The new interface, available in cairo-quartz.h, is as follows: - - void - cairo_set_target_quartz_context (cairo_t *cr, - CGContextRef context, - int width, - int height); - - cairo_surface_t * - cairo_quartz_surface_create (CGContextRef context, - int width, - int height); - -There is an example program available in CVS in cairo-demo/quartz. It -is a port of Keith Packard's fdclock program originally written for -the xlib backend. A screenshot of this program running on Mac OS X is -available here: - - http://cairographics.org/~cworth/images/fdclock-quartz.png - -ATSUI font backend ------------------- -This new font backend complements the Quartz backend by allowing -applications to use native font selection on Mac OS X. The interface -is a single new function: - - cairo_font_t * - cairo_atsui_font_create (ATSUStyle style); - -Minor API changes ------------------ -Prototype for non-existent function "cairo_ft_font_destroy" removed. - -Now depends on libpixman 0.1.2 or newer, (0.1.3 is being released -concurrently and has some useful performance improvements). - -Default paint color is now opaque black, (was opaque white). Default -background color is transparent (as before). - -Renamed "struct cairo" to "struct _cairo" to free up the word "cairo" -from the C++ identifier name space. - -Functions returning multiple return values through provided pointers, -(cairo_matrix_get_affine, cairo_current_point, and -cairo_current_color_rgb), will now accept NULL for values the user -wants to ignore. - -CAIRO_HAS_FREETYPE_FONT has now been renamed to CAIRO_HAS_FT_FONT. - -Performance improvements ------------------------- -Alexander Larsson provided some fantastic performance improvements -yielding a 10000% performance improvement in his application, (when -also including his performance work in libpixman-0.1.3). These include - - * Fixed handling of cache misses. - - * Creating intermediate clip surfaces at the minimal size required. - - * Eliminating roundtrips when creating intermediate Xlib surfaces. - -Implementation --------------- -Major re-work of font metrics system by Keith Packard. Font metrics -should now be much more reliable. - -Glitz backend -------------- -Updated for glitz-0.3.0. -Bug fixes in reference counting. - -Test suite ----------- -New tests for cache crashing, rotating text, improper filling of -complex polygons, and leaky rasterization. - -Bug fixes ---------- -Fixed assertion failure when selecting the same font multiple times in -sequence. - -Fixed reference counting so cache_destroy functions work. - -Remove unintended copyright statement from files generated with -PostScript backend. - -Fixed to eliminate new warnings from gcc 3.4 and gcc 4. - -Snapshot 0.2.0 (2004-10-27 Carl Worth <cworth@cworth.org>) -=========================================================== -New license: LGPL/MPL ---------------------- -The most significant news with this release is that the license of -cairo has changed. It is now dual-licensed under the LGPL and the -MPL. For details see the COPYING file as well as COPYING-LGPL-2.1 and -COPYING-MPL-1.1. - -I express my thanks to everyone involved in the license change process -for their patience and support! - -New font and glyph internals ----------------------------- -Graydon Hoare has put a tremendous amount of work into new internals -for handling fonts and glyphs, including caches where appropriate. -This work has no impact on the user-level API, but should result in -great performance improvements for applications using text. - -New test suite --------------- -This snapshot of cairo includes a (small) test suite in -cairo/test. The tests can be run with "make check". The test suite was -designed to make it very easy to add new tests, and we hope to see -many contributions here. As you find bugs, please try adding a minimal -test case to the suite, and submit it with the bug report to the -cairo@cairographics.org mailing list. This will make it much easier -for us to track progress in fixing bugs. - -New name for glitz backend --------------------------- -The gl backend has now been renamed to the glitz backend. This means -that the following names have changed: - - CAIRO_HAS_GL_SURFACE -> CAIRO_HAS_GLITZ_SURFACE - cairo_set_target_gl -> cairo_set_target_glitz - cairo_gl_surface_create -> cairo_glitz_surface_create - -This change obviously breaks backwards compatibility for applications -using the old gl backend. - -Up-to-date with latest glitz snapshots --------------------------------------- -This snapshot of cairo is now up to date with the latest glitz -snapshot, (currently 0.2.3). We know that the latest cairo and glitz -snapshots have been incompatible for a very long time. We've finally -fixed that now and we're determined to not let that happen again. - -Revert some tessellation regression bugs ----------------------------------------- -People that have been seeing some tessellation bugs, (eg. leaked -fills), in the CVS version of cairo may have better luck with this -release. A change since the last snapshot was identified to trigger -some of these bugs and was reverted before making the snapshot. The -behavior should be the same as the previous (0.1.23) snapshot. - -Miscellaneous changes ---------------------- -Changed CAIRO_FILTER_DEFAULT to CAIRO_FILTER_BEST to make gradients -easier. - -Track XCB API change regarding iterators. - -Various bug fixes ------------------ -Fix calculation of required number of vertices for pen. - -Fix to avoid zero-dimensioned pixmaps. - -Fix broken sort of pen vertices. - -Fix bug when cairo_show_text called with a NULL string. - -Fix clipping bugs. - -Fix bug in computing image length with XCB. - -Fix infinite loop bug in cairo_arc. - -Fix memory management interactions with libpixman. - -Snapshot 0.1.23 (2004-05-11 Carl Worth <cworth@isi.edu>) -======================================================== -Fixes for gcc 3.4 ------------------ -Fix prototype mismatches so that cairo can be built by gcc 3.4. - -Updates to track glitz ----------------------- -Various fixes to support the latest glitz snapshot (0.1.2). - -Gradient updates ----------------- -Radial gradients now support both inner and outer circles. -Transformed linear gradients are now properly handled. -Fixes for extend type reflect. - -Glitz updates -------------- -Converted shading routines to use fixed point values and introduced a -shading operator structure for more efficient shading calculations. -Support compositing with mask surface when mask is solid or -multi-texturing is available. - -PNG backend cleanups --------------------- -Fix output to properly compensate for pre-multiplied alpha format in cairo. -Add support for A8 and A1 image formats. - -Bug fixes ---------- -Avoid crash or infinite loop on null strings and degeneratively short -splines. - -New? bugs in cairo_clip ------------------------ -There are some fairly serious bugs in cairo_clip. It is sometimes -causing an incorrect result. And even when it does work, it is -sometimes so slow as to be unusable. Some of these bugs may not be -new, (indeed cairo_clip has only ever had a braindead-slow -implementation), but I think they're worth mentioning here. - -Snapshot 0.1.22 (2004-04-16 Carl Worth <cworth@isi.edu>) -======================================================== -Cairo was updated to track the changes in libpixman, and now depends -on libpixman version 0.1.1. - -Snapshot 0.1.21 (2004-04-09 David Reveman <c99drn@cs.umu.se>) -============================================================= -New OpenGL backend ------------------- -The OpenGL backend provides hardware accelerated output for -X11 and OS X. The significant new functions are: - - cairo_set_target_gl - cairo_gl_surface_create - -Automatic detection of available backends ------------------------------------------ -The configure script now automatically detect what backends are -available, (use ./configure --disable-`backend' to prevent -compilation of specific backends). - -Snapshot 0.1.20 (2004-04-06 Carl Worth <cworth@isi.edu>) -======================================================== -New pattern API ---------------- -David Reveman has contributed a new pattern API which enable linear -and radial gradient patterns in addition to the original surface-based -patterns. The significant new top-level functions are: - - cairo_pattern_create_linear - cairo_pattern_create_radial - cairo_pattern_create_for_surface - cairo_pattern_add_color_stop - cairo_set_pattern - -Any code using the old cairo_set_pattern, (which accepted a -cairo_surface_t rather than a cairo_pattern_t), will need to be -updated. - -Update to XCB backend ---------------------- -The XCB backend is now enabled by default, (use ./configure ---disable-xcb to turn it off). - -Faster clipping ---------------- -Graydon Hoare has added optimizations that make cairo_clip much faster -when the path is a pixel-aligned, rectangular region. - -Bug fixes. - -Snapshot 0.1.19 (2004-02-24 Carl Worth <cworth@isi.edu>) -======================================================== -New PNG backend ---------------- -Olivier Andrieu contributed a new PNG backend. It builds on the -existing image backend to make it easy to render "directly" to a -.png file. The user never needs to deal with the actual image -buffer. The significant new functions are: - - cairo_set_target_png - cairo_png_surface_create - -The PNG backend is not enabled by default so that by default there is -not a new dependency on libpng. Use ./configure --enable-png to enable -this backend. - -Snapshot 0.1.18 (2004-02-17 Carl Worth <cworth@isi.edu>) -======================================================== -Path query functionality ------------------------- -It's now possible to query the current path. The two new functions -are: - - cairo_current_path - cairo_current_path_flat - -Each function accepts a number of callback functions that will be -called for each element in the path (move_to, line_to, curve_to, -close_path). The cairo_current_path_flat function does not accept a -curve_to callback. Instead, all curved portions of the path will be -converted to line segments, (within the current tolerance value). This -can be handy for doing things like text-on-path without having to -manually interpolate Bézier splines. - -New XCB backend ---------------- -Jamey Sharp has contributed a second X backend that uses the new, lean -XCB library rather than Xlib. It cannot currently be compiled at the -same time as the Xlib backend. See ./configure --enable-xcb. - -Build fixes for cygwin. - -Bug fixes. - -Snapshot 0.1.17 (2003-12-16 Carl Worth <cworth@isi.edu>) -======================================================== - -Better text support -------------------- -This snapshot provides much better text support by implementing the -following four functions: - - cairo_text_extents - cairo_glyph_extents - cairo_text_path - cairo_glyph_path - -The text/glyph_extents functions can be used to determine the bounding -box (and advance) for text as if drawn by show_text/glyphs. - -The text/glyph_path objects functions place text shapes on the current -path, where they can be subsequently manipulated. For example, -following these functions with cairo_stroke allows outline text to be -drawn. Calling cairo_clip allows clipping to a text-shaped region. - -Combined dependencies ---------------------- -The cairo core now depends only on the libpixman library. This single -library replaces the three previous libraries libic, libpixregion, and -slim. Thanks to Dave Beckett <dave.beckett@bristol.ac.uk> for all of -the heavy lifting with this renaming effort. - -Conditional compilation of backends ------------------------------------ -Cairo now allows optional backends to be disabled at compile time. The -following options may now be passed to the configure script: - - --disable-xlib - --disable-ps - -Note that the first option is a change from the old --without-x option -which will no longer have any effect. - -OS X supported - several byte-order issues resolved ---------------------------------------------------- -Cairo has now been successfully compiled under OS X. Testing revealed -that there were some byte-order problems in the PostScript backend and -the PNG generation in the demos. These have now been resolved. - -2003-10 -======= -Graydon Hoare <graydon@redhat.com> implemented the first real text -support using Freetype/fontconfig, (previous versions of cairo used -Xft and could only draw text when using an X backend). - -2003-09 -======= -Graydon Hoare <graydon@redhat.com> added the first real support for -running cairo with a non-render-aware X server. - -Jamey Sharp <jamey@minilop.net> virtualized the backend font and -surface interfaces in September, 2003. - -2003-06 -======= -Xr is renamed cairo to avoid confusion since it no longer had a strict -dependence on X. - -2003-05 -======= -A new image surface backend is added to Xr. Keith Packard -<keithp@keithp.com> wrote the image compositing code in libic that is -used for the image_surface backend. This code was originally written -as the software fallback for the render extension within the X -server. - -2002-06 -======= -Carl Worth <cworth@isi.edu> wrote the first lines of Xr, after Keith -Packard <keithp@keithp.com> proposed the plan for a stateful drawing -library in C providing a PostScript-like rendering model. - - LocalWords: mutex BeOS extraordinaire diff --git a/gfx/cairo/cairo/README b/gfx/cairo/cairo/README index efca44cda..fc801fee3 100644 --- a/gfx/cairo/cairo/README +++ b/gfx/cairo/cairo/README @@ -1,3 +1,8 @@ +Important note: the source code included in this directory is a subset +of the library, insofar as is needed to supply functionality to the +UXP source.
