Maybe you could explain what this code actually does? “Change RGB color” doesn’t really explain anything.. Are you switching so the Red colors become Green? Or what exactly???

Hello,

I suppose 2nd line of
UIGraphicsBeginImageContext(image.size);
is not needed, and should be deleted.
Because my iPad application will crash(actually disappear) if I repeat this method, because of memory shortage.
If I delete the line, works fine.

Could you confirm?

Thank you for your codes, it seems it works fine.

But I don’t understand why you have to do that?
contextRect.size.height -= 15;
What is the magic number “15″?
