apply masks to ofImages at ofPixel level
Forks
Forks pushed to more recently than armadillu/ofxImageMask itself, plus any admin-confirmed fork with commits of its own — worth checking if you're hitting issues with the original.
README
Simple of addon to apply masks to ofImages (with the mask being another ofImage of same size). It also allows to invert the effect of the mask.
I needed this to work on iOS, so unlike the other addons I've seen around, the masking happens at ofPixels level (not using shaders).
