Personal resources for image-processing which include topics like :

• photography
• cinematography
• vfx

You can find 3 software components:

• resources: some test assets (images); they are not version-controlled but you can retrieve them using the provided scripts.
• scripts: python scripts to do image processing
• plugins: to be used in other software

Each tool should come with its own documentation for details.

Most tool (except plugins) will require python and some dependencies.

• uv is installed
• you don't need to install python as uv will manage it for you

Project is managed through uv.

Assuming uv and git are installed and available on your system, executing a script is just a matter of running it with uv:

cd path/you/want/to/download/the/project/to # the git clone step can be replaced by a manual download of the repo git clone https://github.com/MrLixm/image-processing-lxm.git cd image-processing-lxm uv run ./scripts/raw-exr-converter.py

Most of the time scripts are separated in 2 sections:

• parameters: at the top we define global variables to configure the script runtime. You usually need to tweak those depending on your needs.
• processing: the rest of the code that will use the parameters; no modification needed.

So the workflow is mostly:

• edit global variables to match your needs and your system
• run script with uv
• repeat

Make sure to also read the top-docstring of each script that may provide additional instructions.

some of the tools assume you have specific software available on your system:
