What is a .Atlas file?
An .atlas file maps the packed images on a sprite sheet, used with Spine and game engines.
- Did you know
- An atlas lets a game pack many sprites into one image and find each one again.
- Spine’s atlas format is based on the libGDX texture atlas, a line-based text file listing each page image and the regions packed into it.
- By packing many small images into one larger page, an atlas lets a game render many sprites with far fewer texture switches.
- What Analyser reads
- Identify and read more game and emulator files: Unity asset bundles, Unreal cooked assets, CISO/CHD disc images, FMOD/Wwise sound banks, Spine skeletons and atlases, GameMaker/LDtk/TIC-80 projects, Minecraft Anvil regions, Warcraft III maps, Ren Py and RPG Maker data, extra console ROMs (Atari, PC Engine, Master System/Game Gear, WonderSwan, 3DS homebrew), xdelta/Basis patches and emulator saves and movies.
- Depth of analysis
- .Atlas is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .Atlas file
- Drag a .Atlas file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
