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.

I'm happy to announce the release of the G'MIC package, which should be the latest of the 1.3.3.x serie (unless some critical bugs are found, but this is not planed :p )

For the user, there are absolutely no differences with the previous version. Mainly, the G'MIC engine has been stabilized and slightly improved. There have been lot of small bugs corrected, but nothing spectacular for the plug-in user.

This is in fact what we could called a 'stable' version that is intended to last some months, and which will be the basis for the development of new filters. It means that if new filters are developed in the future, they will be available for the users of this version of G'MIC only (via the 'Refresh' button), to avoid compatibility issues with older versions.

So, feel free to update when you have some free time, but do not wait for something completely different. This is a minor release that ends the 1.3.3.x branch.
Hope you'll like it anyway. I'll keep you informed of new filter developments using this version.

Hello. Apologize for my ignorance in advance. I downloaded the latest version to run on Mac OS X 10.4 (Tiger). When I open it I get the executable file. I'm not quite sure how to install it for use in GIMP 2.6. I put the executable in my plug-in directory but it doesn't appear in my filters. Admittedly, I'm an amateur at best and I'm probably doing it wrong. Any information or help would be appreciated. I'm running G'MIC on a Windows XP computer with no problems and it is an incredible tool for every GIMP user. Thanks.

I'm pleased to announce the version of the G'MIC plug-in for GIMP.

Many internal improvements have been done, for more stability. Also few new features appear in the plug-in :

- A 'Maximize preview' button.
- A 'New active layer(s)' output mode, allowing to create a new layer that is active after the filter output (so that you can use the button 'Apply' multiple times to get modified layers).

I admit I like this release... So, feel free to try out !


Thanks Mahvin,

It should have been corrected now (just 'Refresh' your filters).


Much appreciated.

Be expecting a postcard because I think G'MIC rocks!

Thanks again.

Bummer. All my filters in G'MIC work, except Cartesian custom. I don't feel like repeating everything again, but to condense and the error states:

Filter processing error !

Message returned by the G'MIC engine :

*** Error in ./ *** Command 'gimp_custom' : Command not found.

Using Win 7, GIMP 2.6.8, and default settings. The plug-in was not updated via G'MICs UI, it was downloaded to my local machine. My apologies for the accidental delete.

I'm very happy to announce the release of the version of the G'MIC plug-in for GIMP.

This is an essential release, since I've done great optimizations in the code that just makes things running faster than ever. So everyone using G'MIC should update to this new version, because it gives really a more pleasant user experience.


This is a great set of filters! Thank you!!

I followed accordingly to the instruction by extracting it to the plug-in folder... and nothing happens.
what is the gmic_def1333???
Can guide me... tks!

I just upgraded G'Mic and manually created the new filters definition for it, but its not working. My first question is: Has the function been disabled in Windows versions?

The instructions are to place the def file in either your Home or AppData (Application Data) folder. On Linux, it works just fine. On Windows, however, is a different story. I moved the .gmic_def.1332 to almost every folder (including my home and appdata folders) and it still fails to work.

I did search for the solution, with no workable results.
