CImageDisplay.CheckBitFields method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The CheckBitFields method validates the color masks in a VIDEOINFO structure.

const VIDEOINFO *pInput
);
Parameters

pInput
-
Pointer to a VIDEOINFO structure.
Return value
Returns TRUE if the color masks are valid, or FALSE otherwise.
Remarks
This method verifies that the color mask for each color component is between one and eight bits long, and that each color mask is a contiguous sequence of bits. Call this method only when the biCompression member is set to BI_BITFIELDS.
