Welcome to the GIMP Developer wiki!
What is GIMP?
GIMP is the GNU Image Manipulation Program. It is freely distributed software for such tasks as photo retouching, image composition and image authoring. It works on many operating systems, in many languages.
What is this Wiki for?
On this wiki you'll find resources on GIMP development and hacking, and some frequently asked question like how to report bugs. This wiki will also include tutorials about writing extensions for GIMP, and will include useful information on further extending GIMP. Sometimes, developers may use it for design drafts and such things as well.
Whose is it?
This wiki is currently maintained by some GIMP developers, so if you have any comments, feel free to contact LightningIsMyName or Alexia_Death via the the GIMP IRC (irc://irc.gimp.org/#gimp)
How do I get a user account?
Contact LightningIsMyName at the GIMP IRC (irc://irc.gimp.org/#gimp) or by email (LightningIsMyName at gmail dot com). He is available on IRC usually several hours each day :) Only if not possible, try to contact Alexia_Death, mitch, nomis, prokoudine, schumaml or scl on the GIMP IRC.
Currently existing namespaces are
- Hacking for hacking related pages,
- Users for user guides and the like,
- Specs for attempts at writing specs,
- Mindstorm for idea generation and planning.
Lets try to stick to these. What you have in your user space is your own business :)
- Release for release related pages,
Information here is dedicated to all GIMP wiki readers.

Hot topics and/or very relevant topics at this time
Currently our main priority is porting as much of GIMP to GEGL as possible. Finalizing the switch is the prerequisite for starting the work on major new features such as non-destructive editing or layer effects.
- Hacking:Porting_filters_to_GEGL — the progress of moving to a new image processing core
- Hacking:Porting file loaders/exporters to GIO - the progress of moving the file loaders/exporters to the GIO library
- Specs:UI Theme - the progress, drafts and discussion about another GIMP UI theme
Google Summer of Code
We often participate in Google Summer of Code program. It's a great source of new dedicated contributors.
