A Full-Featured Open-Source Framework for Image Processing

This gallery gives a quick overview of the kind of features and generic filters available in the G'MIC open-source image processing framework.

All the images below have been processed by the CLI interface gmic of G'MIC, from a set of initial 2D color images. Click on an image to enlarge it and display the G'MIC command-line used for the processing (note: to reproduce this, you may have to escape some characters, according to the type of shell you use!).

Remember, G'MIC lets you define your own image pipelines through custom command files. Your custom filters can be easily added afterwards in the plug-in for GIMP or Krita.

For more details, visit the tutorial pages as well as the technical reference to get a full documentation on this software.
