Python binding for G’MIC – A Full-Featured Open-Source Framework for Image Processing
gmic-py is the official Python 3 binding for the G’MIC C++ image processing library purely written with Python’s C API.
Its Python package name on pypi.org is just
This project lives under the CeCILL license (similar to GNU Public License).
You can use the
gmic Python module for projects related to desktop or server-side graphics software, numpy, video-games, image procesing.
Check out the
gmic-py documentation website (readthedocs) for Quickstart, Tutorials, API Reference and
gmic-py third-party integrations.
gmic-py‘s slowly growing community gravitates around:

gmic-blender is a Blender3d add-on bundling
gmic-py and allowing you use a new
gmic module from there without installing anything more.
First install the G’MIC Python module in your (virtual) environment.
pip install gmic
G’MIC is a language processing framework, interpreter and image-processing scripting language.
Here is how to load
gmic, and evaluate some G’MIC commands with an interpreter.
import gmic gmic.run("sp earth blur 4 display") # On Linux a window shall open-up and display a blurred earth gmic.run("sp rose fx_bokeh 3,8,0,30,8,4,0.3,0.2,210,210,80,160,0.7,30,20,20,1,2,170,130,20,110,0.15,0 output rose_with_bokeh.png") # Save a rose with bokeh effect to file
gmic-py Quickstart tutorial is available here.
Tutorials on various topics are available in the documentation.
Full documentation is being written at https://gmic-py.readthedocs.io/.
gmic-py works for Linux and Mac OS x 64bits architecture x Python >= 3.6. Windows support is planned for Q4 2020.
In case your environment is a type of Unix, but compiling from source is needed, note that the
pip installer will download
gmic-py‘s source and most possibly compile it very well.

gmic-py for your own OS.
All examples belong in the examples/ folder.
Some of them correspond to tutorials on

Jupyter / Google Colab / IPython integration
gmic-py provides G’MIC console output retrieval and images
display emulation for IPython/Jupyter/Google Colab environments:

Using your camera with G’MIC’s optional OpenCV linking (advanced)
If your machine has
libopencv installed and you build
gmic-py from source (ie.
python setup.py build), G’MIC OpenCV commands will be enabled.
