Transparency

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?

"semi-transparent"?

sure this mean alpha blending
no, there's no 2d command in blitz+ for that

Ok, nevermind

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
