This class -// handles the creation, selection, de-selection and deletion of these objects -// automatically. It also automatically deletes or releases the device context -// itself as appropriate. Any failure to create the new GDI object throws an -// exception. -// -// The CDC class is sufficient for most GDI programming needs. Sometimes -// however we need to have the GDI object seperated from the device context. -// Wrapper classes for GDI objects are provided for this purpose. The classes -// are CBitmap, CBrush, CFont, CPalette, CPen and CRgn. These classes -// automatically delete the GDI resouce assigned to them when their destructor -// is called. These wrapper class objects can be attached to the CDC as -// shown below. -// -// Coding Exampe without CDC ... -// void DrawLine() -// { -// HDC hdcClient = ::GetDC(m_hWnd); -// HDC hdcMem = ::CreateCompatibleDC(hdcClient); -// HBITMAP hBitmap = ::CreateCompatibleBitmap(hdcClient, cx, cy); -// HBITMAP hOldBitmap = (HBITMAP)::SelectObject(hdcMem, hBitmap); -// HPEN hPen = ::CreatePen(PS_SOLID, 1, RGB(255,0,0); -// HPEN hOldPen = (HPEN)::SelectObject(hdcMem, hPen); -// ::MoveToEx(hdcMem, 0, 0, NULL); -// ::LineTo(hdcMem, 50, 50); -// ::BitBlt(hdcClient, 0, 0, cx, cy, hdcMem, 0, 0); -// ::SelectObject(hdcMem, hOldPen); -// ::DeleteObject(hPen); -// ::SelectObject(hdcMem, hOldBitmap); -// ::DeleteObject(hBitmap); -// ::DeleteDC(hdcMem); -// ::ReleaseDC(m_hWnd, hdcClient); -// } -// -// Coding Example with CDC classes ... -// void DrawLine() -// { -// CClientDC dcClient(this) -// CMemDC dcMem(&dcClient); -// CBitmap* pOldBitmap = dcMem.CreateCompatibleBitmap(&dcClient, cx, cy); -// CPen* pOldPen = CMemDC.CreatePen(PS_SOLID, 1, RGB(255,0,0); -// CMemDC.MoveTo(0, 0); -// CMemDC.LineTo(50, 50); -// dcClient.BitBlt(0, 0, cx, cy, &CMemDC, 0, 0); -// } -// -// Coding Example with CDC classes and CPen ... -// void DrawLine() -// { -// CClientDC dcClient(this) -// CMemDC CMemDC(&dcClient); -// CBitmap* pOldBitmap = dcMem.CreateCompatibleBitmap(&dcClient, cx, cy); -// CPen MyPen(PS_SOLID, 1, RGB(255,0,0)); -// CPen* pOldPen = CMemDC.SelectObject(&MyPen); -// CMemDC.MoveTo(0, 0); -// CMemDC.LineTo(50, 50); -// dcClient.BitBlt(0, 0, cx, cy, &CMemDC, 0, 0); -// } - -// Notes: -// * When the CDC object drops out of scope, it's destructor is called, releasing -// or deleting the device context as appropriate. -// * When the destructor for CBitmap, CBrush, CPalette, CPen and CRgn are called, -// the destructor is called deleting their GDI object. -// * When the CDC object' destructor is called, any GDI objects created by one of -// the CDC member functions (CDC::CreatePen for example) will be deleted. -// * Bitmaps can only be selected into one device context at a time. -// * Palettes use SelectPalatte to select them into device the context. -// * Regions use SelectClipRgn to select them into the device context. -// * The FromHandle function can be used to convert a GDI handle (HDC, HPEN, -// HBITMAP etc) to a pointer of the appropriate GDI class (CDC, CPen CBitmap etc). -// The FromHandle function creates a temporary object unless the HANDLE is already -// assigned to a GDI class. Temporary objects don't delete their GDI object when -// their destructor is called. -// * All the GDI classes are reference counted. This allows functions to safely -// pass these objects by value, as well as by pointer or by reference. - -// The CBitmapInfoPtr class is a convienient wrapper for the BITMAPINFO structure. -// The size of the BITMAPINFO structure is dependant on the type of HBITMAP, and its -// space needs to be allocated dynamically. CBitmapInfoPtr automatically allocates -// and deallocates the memory for the structure. A CBitmapInfoPtr object can be -// used anywhere in place of a LPBITMAPINFO. LPBITMAPINFO is used in functions like -// GetDIBits and SetDIBits. -// -// Coding example ... -// CDC MemDC = CreateCompatibleDC(NULL); -// CBitmapInfoPtr pbmi(hBitmap); -// MemDC.GetDIBits(hBitmap, 0, pbmi->bmiHeader.biHeight, NULL, pbmi, DIB_RGB_COLORS);
