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.

In Script-Fu script such expression cann't work because Scheme dealing with "-stripes_y 3" as a variable (double quotes). Thaks for help but I have to use another solution.

There must be a solution to handle double quotes in scheme expressions. I don't know much about scheme but I cannot imagine you can be really stopped by such a technical detail :)

And an expression within double quotes is not a variable, but a string...

I forget about backslahes before doubleqoute. Scheme also support this feature. Script working. Thank you both for help.

Best regards,

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!
