TexturePackerify

Command-line Texture Packer and Extractor.

Setup

• Install Node.js
• Install ImageMagick (check "Install legacy utilities" during installation.)
• Navigate to your project root and run:

$ npm install texturepackerify

Build Atlases

Place images inside folders. Each folder will be packed to atlas:

src
├── atlas1
│  ├── img0.png
│  ├── img1.png
│  ├── ...
├── atlas2
│  ├── img12.png
│  ├── img13.png
│  ├── ...

Create pack.js:

const texturepackerify = require("texturepackerify");
const config = {
    url: "./src/", //path to atlases. Default: './'
    hashUrl: "./src/", //where to store 'hash.json'. Atlases path will be used as default
    scales: [1, 0.5] //output scales. Default: [1]
    force: false //force rebuild all atlases. By default packed atlases will be skipped
    defaultAtlasConfig: {
        //Override default atlas config: extraSpace, jpeg, extrude, pot, square, colorDepth, animations, spriteExtensions
    }
}
texturepackerify.pack(config, () => {
    console.log("done!");
});

Run:

$ node pack.js

Output:

src
├──...
│  atlas1.png
│  atlas1.json
│  atlas2.png
│  atlas2.json
│  hash.json
│  ...

Atlas Config

Each atlas can hold config.json with parameters:

• "extraSpace" - space between texture frames. Default - 2
• "border" - texture border. Default - 0
• "jpeg" - output to jpeg. Default - false
• "extrude" - add extra pixels in bounds. Default - false
• "pot" - atlas size fixed to power of two. Default - true
• "square" - atlas size fixed to square. Default - false
• "colorDepth" - color depth for texture. Default - 8
• "animations" - parse animations. Default - false
• "spriteExtensions" - add extension to frame name. Default - true

Example

Place config.json in atlas folder:

src
├── atlas1
│  ├── img0.png
│  ├── ...
│  ├── config.json

config.json:

{
    "extraSpace": 0,
    "jpg": true,
    "extrude": true,
    "square": true,
    "colorDepth": 8
}

Extract

TexturePackerify can extract atlases. Place atlas.png and atlas.json to src folder. Create extract.js:

const texturepackerify = require("texturepackerify");
texturepackerify.extract({url:"./src/"}, ()=>{console.log("done!")});

Run:

$ node extract.js
