Gimp

GNU Image Manipulation Program, a sort-of free Photoshop. [L1 ]

CM (28 Jul 2003): In addition to the official scripting language of GIMP (i.e., script-fu, a dialect of Scheme), there are also:

• the Gimp-Perl plugin, which seems to be the most popular scripting language on Gimp together with script-fu, there are numerous available scripts written in Perl for GIMP. Its Home-Page is:

• the Gimp-Python plugin seems up-to-date but not as widely used (no scripts available in the official GIMP registry [L2 ]). Its Home-Page is:

• .. and yes! the Gimp-Tcl used to exist, but the latest version, for Gimp 1.0, seems to be from 1998 :-(

Note: In the same area, we should keep an eye on the upcoming versions of tcl-magick, a Tcl interface to the ImageMagick tools/library. For complex image manipulations, it won't have the power of GIMP though (IMHO of course).

JOB Here is a small shell script example, which uses the script-fu extension:
