DrawDib
[The feature associated with this page, Custom File and Stream Handlers, is a legacy feature. It has been superseded by MediaStreamSource class. MediaStreamSource class has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaStreamSource class instead of Custom File and Stream Handlers, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The DrawDib functions provide high performance image-drawing capabilities for device-independent bitmaps (DIBs). DrawDib functions support DIBs of 8-bit, 16-bit, 24-bit, and 32-bit image depths.
DrawDib functions write directly to video memory. They do not rely on functions of the graphics device interface (GDI).
