composite colors : CALayer and blend mode on iPhone
- by Ali
I'm trying to use core image on the iphone. I'm able to composite my colors using quartz to draw an uiview, but i want to separate each component into CALayer (UIview consume more resources).
So i have a white mask i want to use to filter a background bitmap, and i want to try diffrent blending mode. UNfortunately, the layers are only "adding"…
