Determining If a Driver Can Handle the Input Format

The following example shows how to check the input format with the ICDrawQuery macro.

// lpbiIn points to BITMAPINFOHEADER structure indicating the input 
// format. 

if (ICDrawQuery(hIC, lpbiIn) == ICERR_OK) 
{ 
    // Driver recognizes the input format. 
} 
else 
{ 
    // Need a different decompressor. 
}
