YAAP

Yet-Another-Atlas-Packer by bersK (Stefan Stefanov)

Usage & requirements

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
  • Build the libtinyfiledialog library in the vendors/dialog fold

Description

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.

Dependencies

  • odin-aseprite github
  • raylib (vendor/raylib, link)
  • stb_rect_pack (vendor/stb/rect_pack, link)
