Suppose you have developed a beautiful web template in some vectorial program, now you have to cut it in several partial images to make the html/css/image web template. But some times it is difficult to change the colors in a consistent manner and the cut it again color by color to obtain many color variants. Here is a script that can help you to do it in one step.

Example output:

1. Copy the file tplcolor.scm into your /usr/share/gimp/2.0/scripts/ directory.
2. Run the script in GIMP batch mode from the command line:
   1. gimp -i -b “(batch-colorize-jpg \”*.jpg\” $i $j $k)” “(batch-colorize-indexed \”*.gif\” $i $j $k)” “(batch-colorize \”*.png\” $i $j $k)” ‘(gimp-quit 0)’
3. Or use the bash scrip: gentempl.sh in the same directory of the original template images.

tplcolor.scm script is based on http://www.gimp.org/tutorials/Basic_Batch/
