After much searching about, I discovered (contrary to what the docs say), that NSBitmapImageReps do not always premultiply their r/g/b by their alpha. Because of this, I've dived in, and attempted to write my own premultiplication, but something is going very wrong. Some images are coming out a quarter of the width they went in, others coming out completely empty...
I'd really appreciate someone more familiar with the image APIs taking a stare at my code: http://pastebin.org/201313 Thanks a lot Tom Davie_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
