Change colors an image can use
Sorry if this is a dumb question but I was wondering if there was any way to change what colors make up an image. I have a palette of 400+ colors that I'd like the image to be composed of but I can't find a way to convert it to only use those colors. Changing the mode to indexed mode doesn't work since you can only index 256 max colors.

Is there any plug-ins or tools I am missing that can do this? (Basically it will change every pixel in the image to the closest matching pixel from a large [400+ color] palette.

Thanks in advance Smile

RE: Change colors an image can use
See http://www.imagemagick.org/Usage/quantize/#colors

However, "closest matching pixel" requires a very strict definition, unless you define yourself the closest color for each of the 32 millions colors available in Gimp (see the "-remap" option further down)
