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:
PD_CAN_DRAW_DIB
| DrawDib can draw images using this format. Stretching might or might not also
be supported.
|
PD_CAN_STRETCHDIB
| DrawDib can stretch and draw images using this format.
|
PD_STRETCHDIB_1_1_OK
| StretchDIBits draws unstretched images using this format faster than an alternative method.
|
PD_STRETCHDIB_1_2_OK
| StretchDIBits draws stretched images (in a 1:2 ratio) using this format faster than an
alternative method.
|
PD_STRETCHDIB_1_N_OK
| StretchDIBits draws stretched images (in a 1:N ratio) using this format faster than an
alternative method.
