How do I replace a color with another?

[Larksmann]

Hi there! I'm pretty new to scripting dynamic images, and I'm need to replace one color in an image with another (I know what the color I want to replace is, so I won't have to figure it out first). I couldn't find any PHP functions to do this directly, so I was wondering if anyone here had a clue? I'm using PNGs, by the way.

i know one way you could probably do this is by looping over each x,y coordinate of the image, and using [man]imagecolorat[/man] to see if its the color you want to replace, and then use [man]imagesetpixel[/man] to put the color you want it to be replaced with in that coordinate.

Thanks, that works just fine. There's probably a better way, but whatever.
