GIMP Development

This site tries to provide useful information for developers:

  • If you are into resource creation, e.g. plug-in development, you should look at the Resource Development section.
  • If you wish to contribute to GIMP itself, you should read the Core Development section.

Note: for the main GIMP website, visit www.gimp.org instead; the GIMP manual is at docs.gimp.org .
