Windows GDI+ exposes a flat API that consists of about 600 functions, which are implemented in Gdiplus.dll and declared in Gdiplusflat.h. The functions in the GDI+ flat API are wrapped by a collection of about 40 C++ classes. It is recommended that you do not directly call the functions in the flat API. Whenever you make calls to GDI+, you should do so by calling the methods and functions provided by the C++ wrappers. Microsoft Product Support Services will not provide support for code that calls the flat API directly. For more information on using these wrapper methods, see GDI+ Flat API.
The following flat API functions are wrapped by the CachedBitmap C++ class.
|Flat function||Wrapper method||Description|
|GpStatus WINGDIPAPI GdipCreateCachedBitmap( GpBitmap *bitmap, GpGraphics *graphics, GpCachedBitmap **cachedBitmap )||CachedBitmap::CachedBitmap||Creates a CachedBitmap::CachedBitmap object based on a Bitmap object and a Graphics object. The cached bitmap takes the pixel data from the Bitmap object and stores it in a format that is optimized for the display device associated with the Graphics object.|
GpStatus WINGDIPAPI GdipDeleteCachedBitmap(GpCachedBitmap *cachedBitmap)
|~CachedBitmap()||Cleans up resources used by a CachedBitmap object.|
|GpStatus WINGDIPAPI GdipDrawCachedBitmap( GpGraphics *graphics, GpCachedBitmap *cachedBitmap, INT x, INT y )||Graphics::DrawCachedBitmap||The Graphics::DrawCachedBitmap method draws the image stored in a CachedBitmap object.|
UINT WINGDIPAPI GdipEmfToWmfBits( HENHMETAFILE hemf, UINT cbData16, LPBYTE pData16, INT iMapMode, INT eFlags )
|Metafile::EmfToWmfBits||Converts an enhanced-format metafile to a Windows Metafile Format (WMF) metafile and stores the converted records in a specified buffer.|
