DrawDibProfileDisplay

The DrawDibProfileDisplay function determines settings for the display system when using DrawDib functions.

BOOL DrawDibProfileDisplay(
  LPBITMAPINFOHEADER lpbi  
);

Parameters

lpbi
Address of a BITMAPINFOHEADER structure that contains bitmap information. You can also specify NULL to verify that the profile information is current. If the profile information is not current, DrawDib will rerun the profile tests to obtain a current set of information. When you call DrawDibProfileDisplay with this parameter set to NULL, the return value is meaningless.

Return Values

Returns a value that indicates the fastest drawing and stretching capabilities of the display system. This value can be zero if the bitmap format is not supported or one or more of the following values:

Value Description
PD_CAN_DRAW_DIB DrawDib can draw images using this format. Stretching might or might not also be supported.
