Также, если вы в линуксе, то вы можете установить G`MIC, подключив PPA таким вот примерно образом:
On Unix, the plug-in directory is usually located at $HOME/.gimp-2.x/plug-ins/.
The plug-in requires these libraries installed on your system : libfftw, libpng, zlib. Use your package manager to fit these dependancies.
On Windows, the plug-in directory is usually located at C:\Program Files\GIMP-2.x\lib\gimp\2.0\plugins\.
All required libraries files are provided in the archive.
sudo add-apt-repository ppa:ferramroberto/gimp sudo apt-get update sudo apt-get install gmic gimp-gmic
Installing the G'MIC plugin for Gimp on OpenSuSE Leap
G'MIC features lots of fancy filters. You should perhaps not try them, it steals all of your spare time.
Download the Linux 64 Bit Zip file from gmic.eu . Note: I use KDE, so this is fine.
Copy gmic_gimp_qt to your Gimp plugin folder (see here for finding out, where the folder is).
Run gmic_gimp_qt from the command line. If it complains about being a filter for Gimp, everything is fine. If instead it complains about missing libraries, you should install them. My machine lacked libfftw3_threads.so.3. I installed it with YaST.
Restart Gimp. G'MIC QT is the last entry in the Filter menu.
