Gamefroot Texture Packer

Build Status

Generate high quality texture atlases in Node.js, developed for Gamefroot.com and Kiwi.js.

Features

  • Use growing-binpacking to optimise your texture memory
  • Trim, scale and pad assets to further make use of space
  • Add gutter (bleed) to your images to avoid nasty join lines
  • Add a maximum width/height to conform to platform limitations
  • Generate as many atlases as you need with a single command
  • Use texture groups to ensure optimal run-time performance

Supported spritesheet formats

  • Kiwi.js
  • Starling / Sparrow
  • JSON (i.e. PIXI.js)
  • Easel.js
  • cocos2d
  • CSS (new!)
