The GetBitMasks method retrieves the color masks for a specified VIDEOINFO format.
Syntax
const DWORD *GetBitMasks(
const VIDEOINFO *pVideoInfo
);
Parameters
pVideoInfo
Pointer to the VIDEOINFO structure.
Return Value
Returns an array of three DWORD values.
Remarks
If the biCompression member is BI_BITFIELDS, the method returns a pointer to the color masks that are supplied in the dwBitMasks member. If the biCompression member is BI_RGB, the method returns the color masks that correspond to the bit depth. If the method fails (for example, the bit depth is less than 16), the method returns the array {0,0,0}.
