I’m happy to announce the release of a new version (numbered 1.7.6) of the G’MIC image processing framework. As always, I encourage upgrading to this new version as soon as possible .
This version is backward-compatible with the previous one (1.7.5), meaning that all new filters added in this version have been also backported for users of the previous stable version.
EDIT: Please upgrade to next version 1.7.7, if possible, as two critical bugs have been fixed in color conversion routines RGB->HSL and RGB->HSI. Those functions return wrong results in version 1.7.6.
What is G’MIC?
G’MIC is a full-featured open-source framework for image processing. It provides several different user interfaces to convert/manipulate/filter/visualize generic image datasets, ranging from 1d scalar signals to 3d+t sequences of multi-spectral volumetric images, thus including 2d color images.

The following is the full Changelog of the version 1.7.6, as compared to the previous stable version 1.7.5.
[core] Added support of CMake to build the software (cli interface, gimp plug-in and C++ library). Thanks to Andrea Ferrero (from Photoflow).
[core] The math parser now understands expression
I#ind, which is equivalent to
I(#ind)(access to vector-valued pixel of image
indat current processing position
[core/gimp] New command
-retinexand associated GIMP plug-in filter Colors / Retinex apply the Multiscale Color Retinex algorithm for improving color consistency in images.
- [gimp] New filter Degradations / Flip & rotate blocs allows quite flexible bloc-by-bloc processing of the image. Very cool for generating glitch art.
- [gimp] New filter Degradations / Warp by intensity locally warp an image by its local intensity value. Also cool for generating glitch art.
These two last filters have been inspired by the Polyglitch plug-in for Paint.NET, as described here : http://forums.getpaint.net/index.php?/topic/30276-glitch-effect-plugin-polyglitch-v14b/
-blend_medianhas been recoded from scratch and is now more efficient (faster and less memory-consuming).
[core] Several optimizations have been done in the Cimg Library (base library used for the image processing routines), proposed by Ingo Weyrich and Sébastien Fourey. A big thanks to them!
[gimp] Improved preview rendering when icc profiles are used for color-management (much thanks to Andrea Ferrero for his help!).
[gimp] Filter Degradations / Pixel sort has new options for parameter Sorting criterion.
[gimp] Fixed bug in plug-in when working on a selection of a very small image (filter preview made the plug-in crash).
+ various small bug fixes and corrections, spotted by the community. Thanks folks !
