Hi I'm quite new to 2d stuff in Blitz... I'm trying to make an image semi-transparent...is there any command to do this because I can't seem to find one...I know about maskimage but that just makes a whole section of the image transparent. Can anyone help?

i wrote a DLL for BB2D/BB3D/BB+ - this can blend a buffer to another... But this is not so really fast - Ok it is faster than BB's Read/Writepixelfast - and faster than "Bank"-Peeking/Poking on my P800 i can blend 256x256 ~90 times per second - WITHOUT hardware acceleration... it is not so really fast www.blitzbase.de/downloads/blend.zip
