Yet-Another-Atlas-Packer by bersK (Stefan Stefanov)
Important
Pull this repo with --recursive, the odin-aseprite library is pulled in as a submodule.
At least odin compiler version dev-2025-07:204edd0fc
Since we need to download/compile some 3rd party dependencies in the vendors folder we need to call
scripts/setup.[sh|bat] to compile libtinydialog & download the already compiled clay binaries and bindings.
Note
Quite frankly if you want automatic atlas packing I would suggest using stb_rect_pack directly & an aseprite plugin for exporting your assets in a proper format for packing. Using this atlas packer in an automated fashion is not quite possible and slower as a workflow. I would only use it for experiment projects or places where having a built in atlas packer is not practical.
Simple atlas packer for .aseprite files. Generates a packed png & metadata in the form of json and/or source files(cpp, odin, etc...).
Caution
Does not handle palette files currently.
Uses stb_rect_pack for the image packing & raylib for the UI.
A quick preview on youtube.
