Introduction
The GIMP AppImage is built on CentOS 7, using a custom Docker container that provides all the required up-to-date dependencies.
The compilation of the BABL/GEGL/GIMP code under Docker is performed by the build-appimage-centos7.sh shell script, while the AppImage bundle is created and packaged by the package-appimage.sh script.
A second step in the build process compiles a set of useful plug-ins (build-appimage-plugins-centos7.sh), which are then bundled into an additional, full-featured AppImage package.
The whole build process is automated with Travis CI, using this configuration file. A cron job is scheduled to run on a weekly basis and builds the git HEAD version of BABL/GEGL/GIMP. The updated AppImage package is automatically uploaded to the continuous release page.
GIMP plug-ins
Several GIMP plug-ins that can work in combination with the AppImage can be downloaded from here.
This is the current list of available plug-ins:
- Resynthesizer - texture synthesis
- Liquid rescale - content-aware image resizing based on seam carving
- NUfraw - RAW image processing
- G'MIC-Qt - the plug-in for the G'MIC filters library
- PhFGIMP - front-end for the PhotoFlow editor
Follow the instructions in the plug-ins release page to install them in your system.

The AppImage uses a modified version of the exec-wrapper originally available from here:
