	Quick Info

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.
