Hello folks !
This is the changelog for the release of a new minor version (numbered 2.0.4) of the G’MIC image processing framework. This new stable version stays (mostly) compatible with the previous version 2.0.3.
What is G’MIC?
G’MIC (GREYC’s Magic for Image Computing) 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.

- G’MIC download : http://gmic.eu/download.shtml
- G’MIC web service : https://gmicol.greyc.fr/
- G’MIC language tutorial pages : http://gmic.eu/tutorial/basics.shtml
The following is the full Changelog of the version 2.0.4, as compared to the previous stable version 2.0.3.
Enjoy !
New features:
- [gmic-qt] Language selector for the GUI has been added in the Settings menu.
- [core] New native command
-evalwhich does nothing else than evaluating his argument as a math expression and return the result. Similar toeval : -u {"$*"}.
Improvements / Changes:
-
[core] Convolution/correlation and erode/dilate commands now return a result having
max(nb_channels(image),nb_channels(kernel))channels. This allows for instance to convolve a scalar image with a multi-channel kernel, and return a multi-channel image. -
[core] Math parser gets a bunch of new functions:
l()returns the number of images in the associated image list (roughly the same as constant variablelexcept that its value is re-evaluated, useful when the number of images is changing during the evaluation of an expression, e.g. by usingextern()).vtos(expr,_nb_digits,_siz)returns a vector of sizesizwhich contains the ascii representation of values described by expressionexpr(may be a vector, i.e. several values).stov(str,_starting_indice,_is_strict)returns the value described by a string. It replaces the previous functionstod()defined in previous versions.cats(str1,str2,...strN,siz)returns a vector of specifiedsizewhich contains the concatenation of all given string arguments.echo(str1,str2,...,strN)prints the concatenation of given string arguments on the terminal.ext(str1,str2n...,strN)allows to execute a G’MIC command inside the math parser, so you can operate on your images if necessary while evaluating a math expression. The command is seen as the concatenation of given string arguments.argkth(k,arg1,arg2,...)returns the indice of thekthsmallest argument.
Bug fixes:
- Fixed bug when removing multiple fave filters in
gmic-qt. - And as always, many minor bug fixes !
