ugly egdes with scaleimage

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.

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

same problems here. actually, scaling at all pretty much wrecks images 4 me

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