gmic is the open-source interpreter of the G'MIC language, a scripting language dedicated to designing potentially complex image-processing pipelines and operators.
It can be used to convert, manipulate, filter and visualize image datasets consisting of one or more 1D, 2D or 3D multi-spectral images.

This reference documentation describes all the technical aspects of the G'MIC framework, in its current version 4.0.1.
