G’MIC 1.6.7 Magic Image Converter released

G’MIC 1.6.7 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.


G’MIC 1.6.7 changelog

New features:

  • New native command -patchmatch that is able to find a correspondence map between two images, by comparing their respective patches.
  • When updating a variable value in G’MIC (ouside the math parser), you can now use the math operators +=,-=,…<<=,>>= for numeric variables (the same as in C).
  • Embedded math parser can now get/set pixel values of any images in the list, with new expressions w#ind,..,i[#ind,x,y,z,..).
  • New command -syntexturize_patch and associated GIMP filter Pattern / Resynthetize texture [patch-based]. This command re-synthetize an input texture to an output image of arbitrary size.
  • New filter in GIMP plug-in : Black & White / Freaky B&W which resolves a Poisson equation to do color to B&W conversion.


  • Math parser has been slightly optimized (particularly for Windows).
  • Displaying a big volumetric image with the interactive window is now slightly faster.
  • Interactive data viewers for images, 3d objects and function plots have the option not to return when the user press a key on the interactive window (enabled by default).
  • When displaying an image, mouse wheel now activates zoom in/out (instead of CTRL+wheel) before. To go up/down, use CTRL+wheel (instead of wheel before).
  • Replacement of expression $? is now done at the very last time, when needed. This avoids creating temporary strings that won’t be used most of the time.
  • The plug-in update system now looks for updates less frequently (once a week).

Bug fixes:

  • Fix bug in tiff loading for images with bitpersamples==4.
  • Fix small bug in command -warp when used with warping fields having more than 3 channels.
  • Command -watershed now propagates float-valued labels correctly (was rounding them before).
  • Reading 1bits-per-sample binary tiff images now works as expected.
