I was wondering if there is a way to replace one color for another in an
image? Let's say I have an image with a white background and a number of
solid color figures (circles) in say red color. I need to replace those red
circles into black ones. If not gdlib, could you suggest a way I can go
here?

Thank you,
Andrew
