A framework to help handling layeredimage attributes (and image attributes in general, really, it's not at all specific to layeredimages) in Ren'Py.
The attributes_manager.rpy file contains the code itself.
It contains classes whose exact features are documented in their docstrings.
The script.rpy file (TBD) contains an example as to how to use it with the assets of the images/ folder,
as well as a comparison with how the same thing would be done vanilla-style.
Use it freely in any project, just drop my name in the credits, and add a link to this repo if you liked it 🥰
