I'm newbie in graphics and there is really raw explanation of Xfermode
class in Android documentation for me.
Searching the web, I found only relation with such terms like: color blending, image compositing, small explanation about Transfer modes algorithms, source color, destenation color and op color (that means opacity color if I'm not wrong). But it didn't give me enough understanding.
Is there anybody who could explain me this terms, or better give me a link where I can study their explanation?
