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.

The links at Sourceforge (listed at the top of this post), were not the providing the correct updated files (possibly hadn't been updated at the time after David posted it?). They were the older files.

I had to go to the flickr G'MIC site to get the correct link to the updated Sourceforge links.

Thanks David. Downloaded the pre-release yesterday, but saw on the flikr thread that you were going update it again so I just downloaded and installed it. Still a happy camper. :)

I'm really pleased to announce the release of the final version of the G'MIC package.

Hope you'll enjoy it !

Hi! I'm using Mac OS X and I'm really, really interested in adding G'MIC to my GIMP plug-ins 'coz I think it's really cool. However, after a couple of hours of figuring things out, I really couldn't find it in my filters list. i wonder what went wrong. Basing on the thread here, I made a parent folder on my desktop with the zip file in it and i extracted it right there and I came up with a unix executable file. Then I opened GIMP, then went to Edit - Preferences - Folders - Plug-ins, then I clicked the white paper icon at the upper left of the window, then went to my desktop, clicked the G'MIC folder and hit ok. I restarted GIMP but g'mic is not in my filters list still. I would be very happy if you could help me out. Thanks!

Hi folks,

The version of the G'MIC package has been released.

Nothing really exciting here, mainly bug corrections and some new features (but not yet included as usable filters in the GIMP plug-in), as the watershed image transform (will be probably used soon to get a 'mosaic' filter in G'MIC).


I know of no other filter sets, plugins, etc that beat G'MIC.. I'm continually amazed at the different things I've been able to do with it even though I often forget how I did things with it because my age isn't in the low digits anymore. ;)
I studied art years ago and my dad was an old newspaperman and sold artist separated color stuff for years before retiring in the 90's and the techniques I can do with G'MIC would have taken me hours, days or even weeks, sometimes MONTHS to do only a very few short years ago. My dad is completely and utterly floored by it.
My dad thought artist separated color was cutting edge until the computer monitor and mouse came along making those messy old techniques all but completely archaic and outdated and I spent years learning how to do things with pen and paper, ink and brushes that I now do with mouse and monitor in mere minutes.

Thanks....I think ;)

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...
