Tool for using GIMP batch mode to generate images that are transformed from source image files in website projects. Projects that use this tool can define and track the source image files and the GIMP Script-Fu script file or files that are run in order to generate their distribution images. They do not then need to track those distribution images.
To install this tool in projects, add it as a Git submodule with the submodule path tools/gimp. The tool is implemented as a Docker Compose service. Add the path to its docker-compose.yml file to the paths defined by the COMPOSE_FILE Docker Compose environment variable in the project's Docker Compose .env file.
In the project's master docker-compose.yml file you must then extend the gimp service provided by this tool so that the .scm script or scripts that you want to execute are in the /gimp folder for that service's containers. You also need to map the source images and the location(s) for distribution images into the container, exactly where is dictated by your .scm script or scripts.
You can then run this tool from the root folder of your project, either without any command arguments:
docker-compose run --rm gimpIn which case it will run every .scm file within the folder that you mapped to /gimp in the container.
Or, you can specify one or more .scm scripts that are located in the same folder, omitting the file extension; for example:
docker-compose run --rm gimp theme libraryThat example will run the theme.scm and library.scm scripts, if they are present in the folder that you mapped to /gimp in the container.
Here are some of my repositories that use this tool:
