binpacking

This project is a javascript experiment to write a binary tree based bin packing algorithm that is suitable for generating CSS sprites.
You can play with the demo here You can find a description here > Note: the node demo is quick and dirty. Npm support, test suite coming soon...
Clone this repository:

git clone https://github.com/jsmarkus/node-bin-packing

See usage example: https://github.com/jsmarkus/node-bin-packing/blob/master/node-test.js
Run the demo:

node node-test.js

Clone this repository

git clone https://github.com/jsmarkus/node-bin-packing

View the index.html file in your favorite browser for examples of algorithm in use with lots of configurable options.If you want to use this in your own javascript projects, you need something like this:

<script src='packer.growing.js'></script>
<script>
  var packer = new Packer(1000, 1000);   // or:  new GrowingPacker();
  var blocks = [
    { w: 100, h: 100 },
    { w: 100, h: 100 },
    { w:  80, h:  80 },
    { w:  80, h:  80 },
    etc
    etc
  ];

  blocks.sort(function(a,b) { return (b.h < a.h); }); // sort inputs for best results
  packer.fit(blocks);

for(var n = 0 ; n < blocks.length ; n++) {
  var block = blocks[n];
  if (block.fit) {
    DrawRectangle(block.fit.x, block.fit.y, block.w, block.h);
  }
}
    </script>
