How to globally replace one color with another using Imagemagick command line (Win XP)?
I'm using Imagemagick and a scripting language called Macro Scheduler on Win XP to batch-process images prior to putting them online. I would like to globally replace one color with another but I don't know Imagemagick that well and need a little help. It looks like the -clut option might do this, but I don't understand how to use the color lookup table to accomplish it or what that means. Can anyone help?
