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. |
