G'MIC is a framework for digital image processing. It offers a command-line tool, a C++ library with a C API, and a plug-in (G'MIC-Qt) that adds filters to image editors such as GIMP, Krita and digiKam. There is also a web service, G'MIC Online, and a real-time video interface called ZArt. Photographers, illustrators and developers use it to apply, script and automate a large collection of filters and image operations, on single images or in batches.
G'MIC has been developed since 2008, mainly by the Image team of the GREYC research laboratory in Caen, France, a research unit associated with the CNRS. The software is distributed under the CeCILL free software licences, which are LGPL-like and/or GPL-compatible. The command-line tool, the library and the plug-in run on your own computer, so your images stay local unless you choose to use the online service. Because the source code is public, you do not depend on a single commercial supplier.
