What is it?
openlut is a practical color management library/tool that aims to simplify and unify all the various methods of making accurate color transformations.
Supported transforms include:
- 1D and 3D LUTs
- Color Matrices
- Gamma Function
- CDL Transform
It's built on my own color pipeline needs - I needed a simple but close-to-the-math solutions that dealt not with images, but with float arrays.
As a tool, its main feature is that it's exceptionally easy to import, transform, and then save not only images, but also transforms.
Docs can be found at https://sofusrose.com/openlut. They're a work in progress for now (ColMap is 100% documented).
Check Versions: Ensure you have Python 3.5+ installed.
Get System Dependencies - needing to do this is an unfortunate side effect of PyPi.
- On Debian/Ubuntu:
sudo apt-get install python3-pip gcc libmagickwand-dev
- On Mac:
brew install python3 gcc imagemagick
- On Debian/Ubuntu:
Ensure Core Python Packages are Up To Date: Simply run
pip3 install --user -U pip setuptools wheelto do so.
Install OpenLUT: Run
pip3 install --user openlut.
- This may take awhile, as it must compile the C++ Extension.
Clone the Repository: This is easy enough to do - just run
git clone https://www.github.com/so-rose/openlut.
Compile Openlut: Again, very easy - just run
./build <TARGET>, where
<TARGET>is some build target as listed in
Pip doesn't work: If Python is installed, but pip won't run, try running
curl https://bootstrap.pypa.io/get-pip.py | python3
Doesn't work on Windows: I'm unsure of how pip compiles C Extensions on Windows, and have little willpower to investigate. If you need Windows support, PM me and I'll see what I can do about it.
Something's broken...: There may be several bugs. If you start an Issue, then I can investigate.
