ICDrawQuery macro

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.

Syntax

void ICDrawQuery(
   hic,
   lpbiInput
);

Parameters

hic

Handle to a driver.

lpbiInput

Pointer to a BITMAPINFO structure containing the input format.

Return Value

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.
