So, there is my code (Swap is a TAGFIMage)

Code:
Swap.TransparentColor := $007575;

Map[mx,my].Pattern := ImageList.AddImage(Swap);
Proceed the Transparent color automaticly to the Imagelist? When i try to Draw the ListEntry (with effectSRCAlpha) i got white Pixels on the Position of the Transparent Pixels.. is there a way to make it right?
