G’MIC 1.6.9 Magic Image Converter released

G’MIC 1.6.9 recently released, is an open and full-featured framework for image processing, similar to Gimp, providing several different user interfaces to convert, manipulate, filter, visualize generic image datasets, from 1d scalar signals to 3d+t sequences of multi-spectral volumetric images.

A lot of cool stuffs have been added to the G’MIC core engine (particularly the math parser), to make more cool and cool filters in the future.


G’MIC 1.6.9 changelog

New features:

  • New command -frame_seamless and associated plug-in filter Arrays & tiles / Make seamless [patch-based]. It inserts an inner or outer frame to an input image/texture so that seams are less visible when the input image is tiled.

  • New filter Deformations / Continuous droste in the GIMP plug-in. This is a direct conversion of the Droste filter written originally for Mathmap

Martin also converted another Mathmap script, named the Kitaoka Spin Illusion.

  • New filters from Andy (GarageCoder) have been moved from Testing/ into the main branch. Lot of cool filters to discover !


  • Embedded math evaluator has been greatly improved and optimized. It now supports manipulation of vector-valued variables. Lot of new functions have been added to deal with vector/complex-valued arguments : cabs(),carg(),cexp(),clog(),cconj(),operator**,operator//, etc..
  • Math evaluator also allows the user to define their own custom functions.
  • String substitution by the evaluation of a math formula can be vector-valued now. For instance expression {[w,h,d]} is equivalent to expression {w},{h},{d}.
  • Added support for saving bigtiff files (more than 4Gb).
  • Makefile has been slightly improved (use of the CXX pre-definition).
  • Better management of some exceptions in the G’MIC source code.
  • [gimp plug-in] : Added code to check if the dialog window is entirely visible on screen, otherwise try to reduce the preview size as much as possible.
  • New mascot Gmicky designed by David Revoy9.

Bug fixes:

  • When overriding variables x,y,z,c in the math parser, keep consider the original running values ofx,y,z,c when accessing a pixel value with default arguments.
  • Update filter command now allow first-level section names to be translated into a specific language (done for Japanese).
  • Drop support of GIMP 2.6 for the G’MIC plug-in. The plug-in has been not tested on GIMP 2.6 for a while, and I doubt this is still working.
  • A lot of small bug fixes !
