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 writing script which using a G'MIC comands. I need to apply comand "-stripes_y 3" to lightness channel but I cann't figure it out. I have read G'MIC reference about "-apply_channels" comand but it too complex and I didn't find any examples of applying channels. Please help me with it.
Best regards,

G'MIC is out.
Few 'visible' changes but again a lot of bug corrections and small improvements.

Thanks David; downloaded it an hour ago. :)

The final version of the G'MIC plug-in has been released.
It ends the 1.3.5.x serie, and is intended to be a stable one.
Enjoy !

The update of the G'MIC plug-in is available.

Here is the list of improvements :

- Fixed a bug when reading custom command files made in Windows (the classical CR/NL difference with Unix caused problems). So, if you plan to design your own G'MIC filters one day, please update to this latest version :)

- Added a new 'deriche' command in the G'MIC engine, allowing to speed up computations of horizontal and vertical blurs.

- Added options (fps and bitrate) when saving movies , using 'gmic' from the command line.

- And I corrected 4 or 5 minor bugs remaining, concerning the memory management and the way the G'MIC engine displays internal messages (when 'output messages' button is set to 'Verbose' or 'Debug', for instance).

Hey, I would really like to get this plugin, but i don't like the idea of it downloading things automatically. I'd prefer to install everything on my computer manually and keep track of it.

Is there and option to disable this feature?

I just don't want to uninstall it in the future and have to hunt down downloaded files. Very tedious and time consuming! I use my package manager for everything in Linux!

It doesn't download data from the Internet automatically.
It's only when you press the 'Refresh' button, with the 'Internet update' toggle button checked that it connects to the G'MIC server.
This is only an input request, no output data are send to the server.
(you can check the source to be sure :) )

There is now the version of the G'MIC package available.

I clicked the link above and cleared my hard drive of the older version (including recycle bin) and its not updating to the newest G-Mic. Showing as

I had to go to the flickr site to get the updated version. As of last night, the link at the top of this post hadn't been updated.

You will need to go the the Sourceforge site and re-download G'MIC and replace those files Mahvin. No automatic way of updating the plugin itself. :)
