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.

G'MIC has been written by the author of GREYCstoration, a GIMP plug-in dedicated to image denoising and smoothing. All former GREYCstoration algorithms have been improved and integrated into G'MIC.

Latest version of G'MIC is numbered :

A quite complete overview of available image effects can be seen on the official G'MIC plug-in page.

Actually, I've been hoping that someone (else than me) can find it useful.


I'm happy to announce the release of the binary update of the G'MIC plug-in for GIMP. There is actually only minor 'visible' improvements compared to previous versions, mainly bug corrections and improvements of the internal engine.
This is probably the latest release of the year, so I hope you'll enjoy it.



Any thoughts on exposing the parameters for use when scripting? It would be nice to be able to call the GMIC plugin from a script.

That's a very nice idea, and I have some clues to do it.
But unfortunately, I'm not enough aware of how GIMP scripts work.
As G'MIC defines itself a complete language, it would be quite easy to manage, since the plug-in would require only a single parameter : a string, containing the code to execute in the G'MIC language. Then, all existing G'MIC filters could be called this way.

Doesn't look too complex to do I guess. But I need some time to investigate how this can be done, except if someone has some ideas on how to do this faster than me. Do not hesitate to contact me !

As i wrote even before you created a way to call gmic from a script somebody somehow created a gimp script that use and require GMIC

actually i see also a recent complain on that script
i am not sure if the complain is correct
(...or if is from somebody that installed the script but not GMIC ...)

This was just a interactive call. The script open the G'Mic toolbox and then the user have to select everything manually. With the new G'Mic you can use it in non interactive mode without any manual operation.

Dear all,

I finally had some time this week end to look at how a script-fu could call filters from the G'MIC plug-in directly, without having to use the command-line version 'gmic'. This was not too hard at all, since the GIMP plug-in API eases a lot of work. So, now it is possible to do so. Please, take a look at the example script I provide in the G'MIC source package :

I've started to update the plug-in on the G'MIC website. Already available for Linux, should be available for Windows before the end of the day.
I didn't change the version number since this is only a small patch that has been finally applied on the plug-in code.

Let me know if you think this is a useful stuff.


Here in th registry i saw a plugin that require and call GMIC

i can't remember the name now
(or if was a python script)

You can already call a g'mic command line from a python-fu. Of course you need g'mic command line installed and not only gmic4gimp. To call it from a script-fu a solution could be to create a second menu entry called g'mic command line where a string as command line will be the single parameter. Then any script or plug-in could call it.

I only see the tarball and the .deb files.
