A
BITMAPINFOHEADER structure that contains color and dimension information for the video image bitmap. If the format block contains a color table or color masks, they immediately follow the bmiHeader member. You can get the first color entry by casting the address of member to a BITMAPINFO pointer. When used inside a VIDEOINFOHEADER structure, the semantics of the
BITMAPINFOHEADER structure differ slightly from how the structure is used in GDI. For more information, refer to the topic
