Queries a rendering driver to determine if it can render data in a specific format.

• Returns ICERR_OK if the driver can render data in the specified format or ICERR_BADFORMAT otherwise.

wparam

Address of a BITMAPINFO structure describing the input format.

This message differs from the ICM_DRAW_BEGIN message in that it queries the driver in a general sense. ICM_DRAW_BEGIN determines if the driver can draw the data using the specified format under specific conditions, such as stretching the image.
