Change image's content?

[AaronLiao]

Hi guys,

I have a question. Does it possible change the content of an image? For example, there is only a triangle in an image and i want to just change the color of the triangle, but other areas' color are the same. Is there any method to capture the triangle's area and modify it's color. Core Graphics can make it possible?Please help me. I will appreciate that!
