Antialias edges?

BlitzPlus Forums/BlitzPlus Programming/Antialias edges?

Anyone got any cool code that allows you to do a draw image but where the background of the image is transparent (ordinary mask) and the edges of the image (say it's a text logo) are antialiased onto whatever you are drawing. This would be the equivalent of "feathering" in paint programs.

I have found some anti-alias code but nothing to do edge detection, guess I could write one but thought I'd ask first.

Thanks for any help!

The scaleimage command automatically antialiases things. You could use it without any rotation or anything and it should work fine.

Yeah thanks Arem, I noticed that before. In the end I wrote a routine that uses an Alpha map. It's in the code archives.
