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.

Thanks a lot for your encouragements, this is with stories like this that I am motivated to continue the work !


No problem with a image size of 2500x3340 but when I use a image with a size of 5000x6680 it chrashes. Seems a memory problem because I got the following error:

Filter processing error !

Message returned by the G'MIC engine :

*** Error in ./warhol/*repeat/*local/append_tiles/*repeat/*local/ *** [instance(0,0,0,0,00000000,non-shared)] CImg::CImg() : Failed to allocate memory for image (5001,6681,1,3).

I installed the latest version of G'MIC but I can not find it in Help> Plug-In Browser. Where can I find it, e.g. Filters or Layers? I assume under Filters, but which name? I use GIMP 2.6 and Windows 7. Why is it not in the list of the Plug-In Browser?

I am frustrated today. I can't find any scripts in my GIMP. I put t his GMIC in as instructed, I extracted it direclty into the plugins folder under Users/Administrator/gimp2.6/plugins. When I extracted, it created a folder called gmic_gimp, which contains several .dll files and a folder which contained one file called curl.

When I go to Gimp, nothing appears in the filters tab.

Should I have just put the files in and not extracted them the way I did? It seems odd to end up with a folder inside the pluggins folder.

If anyone can re-direct me, I sure would appreciate it...

I recommend you keeping the G'MIC files in a separate location from the plug-in folder and then point Edit-Preferences-Plug-ins folders to the location of the G'MIC executable, with the curl.exe in a child folder. Placing a plug-in with accompanying .dll files into the .gimp-2.6/plug-ins folders has caused issues for me, and I would strongly discourage doing so.

In other words, create a parent folder called G'MIC (it doesn't matter where you put this folder), extract G'MIC zip into it, open Edit - Preferences - Plug-ins in GIMP, create a pointer and then browse to the G'MIC folder you created, select "OK".

That explained by mahvin is the best way to install texpecially for plugin that are not contained in a single file but include several dll and exe files

Also in case of upgrade or unistall will be hard clean up (hard to remember which dll belong to wich plugin , also because usually the file names are totally unrelated ) with the risk to forget behind orphan dll

Mine always shows at the very bottom of the Filters menu.

Just uploaded the new GMIC and when applying any filter, it hangs, becomes unresponsive, then crashes. Using GIMP 2.6.8 in Win 7.

It appears to be a resolution issue. The image I was using to test the new G-MIC was 2200 x 3500, once I scaled it back to 1/4th its size, GMIC worked fine. Is there a limit to what size images GMIC will work with or not? (apparently its not working with my large files, but curious to know if there is a specific limitation).

I'm very happy to announce the release of the version of the G'MIC package, containing as usual the plug-in for GIMP, but also the command line version of the G'MIC interpreter, and the development library to integrate G'MIC capabilities in third-party softwares.
There have been very few improvements on the plug-in itself, but interesting things concerning all the other aspects of G'MIC :

- The improvement and stabilization of the G'MIC language interpreter.
- The improvement of the G'MIC reference manual, with the hope that more people will try to look at the G'MIC script language to design their own filters/effects :
- Texture mapping in 3D objects is now available in G'MIC. Very few commands use it for now on, but this definitely opens interesting ways for the design of interesting image filters.
- There have been also lot of small bug corrections and code improvements.

Hope you will appreciate this version. The G'MIC project has reached a state where it mainly 'converges' into something more stable and usable, but without a lot of big differences between successive versions (which is good in a sense, meaning it becomes mature).

I feel kinda stupid asking this (I am very tech-savvy), but where do the files in the archive go? I use Windows Vista (and I hate it). Do I put them in the application folder or the folder in C:\Users\\.Gimp-2.6\* (* representing whichever folders they would need to go into in this case)?
