The G’MIC plug-in for GIMP proposes a set of various filters to apply on your images, including artistic effects, image denoising and enhancement algorithms, 3D renderers, etc. It is a quite large plug-in, integrating a lot of different effects.

This plug-in is able to :

• Propose an image preview window for each available filter.
• Manage multi-layers inputs and outputs. G’MIC defines filters to compose layers or create animations from static images.
• Update his list of filter definitions from the Internet, so it is able to improve itself over time.
• Allow any user to add its own custom filters in it, written in the G’MIC language interpreted by the internal image processing engine.
