Much of the power of GIMP, the GNU Image Manipulation program, comes from its plug-in architecture. Most of the functions you use in GIMP, including everything in the Filters menu, are plug-ins.
In this talk, you’ll learn to write your own GIMP plug-ins in two languages: Python and Script-fu.
Python is rapidly becoming the language of choice for GIMP plug-ins because of its flexibility and clean API. You’ll see how Python’s access to raw pixel data in an image gives it a huge advantage over Script-fu, and how you can use Python-GTK to create user interfaces far beyond GIMP’s usual plug-in dialogs.
Script-Fu is GIMP’s native language, installed in every version of GIMP. Script-fu is a variant of Scheme, but you don’t need to be fluent in Scheme or Lisp to write Script-fu. You just need to know a few basics of Lisp syntax and how to find the right GIMP call to do what you need. I’ll also cover some of the script-fu changes introduced in 2.4, how to update older scripts, and how to make sure your new scripts will run on all GIMP versions.
