ICDrawQuery
The ICDrawQuery
macro queries a rendering driver to determine if it can render data in a
specific format. You can use this macro or explicitly call the ICM_DRAW_QUERY message.
DWORD ICDrawQuery(
|
hic, |
|
|
lpbiInput |
|
|
); |
|
Parameters
hic
Handle of a
driver.
lpbiInput
Address of a BITMAPINFO structure containing the
input format.
Return Values
Returns ICERR_OK
if the driver can render data in the specified format or ICERR_BADFORMAT
otherwise.
Remarks
This macro
differs from the ICDrawBegin macro in that it queries the driver in a
general sense. ICDrawBegin determines if the driver can draw the data
using the specified format under specific conditions, such as stretching the
image.
