Hi Alan,

The brute force approach is to set the pixel individual using the TDibGraphic.RGB property and replace the transparent color pixels with your background color.

I will send you some test code which allows loading TIconGraphic with a background color, but they it not save with a transarent color.

Best regards,

Michel
