Perhaps this is normal... but is it normal that the transparency is out of control while blowing up an image I have a 20x20 tile tileset and I want it to blow up to 40x40 pixels. the alpha color is (ofcourse 255,0,255) when i try to scaleimage the set the tiles contain a purple edge (quite ugly) I must say that I use the tformfilte Is blowing up maybe a 3D technique? ? :) in the early 3d games I saw this phenomenon quite often. more importaint... can this be avoited?

You say that you are using TFormFilter, set to true I assume? If this is the case then TFormFilter False should remove your ugly borders. Jason.

Ofcourse I know. The case is that I _want_ to use tformfilter

It's a bug introduced with latest B+ version. Here it only occurs on 16-bit screens.
