2D rectangular bin packing algorithms for the Haxe [bin-packing haxelib](https://lib.haxe.org/p/bin-packing). Run the demo [in your browser](https://tw1ddle.github.io/Rectangle-Bin-Packing-Demo/index.html).

Based on the public domain C++ bin packers by [Jukka Jylänki](https://github.com/juj/RectangleBinPack).

## Features ##

* Several fast approximate bin packing algorithms.

* "Occupancy rate" measure to compare packing performance.

* Configurable packing heuristics.

## Usage ##

Run the [demo](https://tw1ddle.github.io/Rectangle-Bin-Packing-Demo/index.html) in your browser and refer to the [example code](https://github.com/Tw1ddle/Rectangle-Bin-Packing-Demo/).

Basic usage example:

```haxe

// Initialize a bin packer

var binWidth:Int = 800;

var binHeight:Int = 400;

var useWasteMap:Bool = true;

var packer = new SkylinePacker(binWidth, binHeight, useWasteMap);

// Start packing rectangles

var rectWidth:Int = 20;

var rectHeight:Int = 40;

var heuristic:LevelChoiceHeuristic = LevelChoiceHeuristic.MinWasteFit;

var rect:Rect = packer.insert(rectWidth, rectHeight, heuristic);

if(rect == null) {

    trace("Failed to pack rect");

} else {

    trace("Inserted rect at: " + Std.string(rect.x) + "," + Std.string(rect.y));

}

```

## Install ##

Get the Haxe library code here or via haxelib.

Include it in your ```.hxml```

```

-lib bin-packing

```

Or add it to your ```Project.xml```:

```

```

## Notes ##

* The algorithms in this haxelib are ported from public domain C++ code by [Jukka Jylänki](https://github.com/juj/RectangleBinPack).

* For details about the algorithms, see Jukka's [blog posts](https://clb.demon.fi/projects/even-more-rectangle-bin-packing) and [paper](https://clb.demon.fi/files/RectangleBinPack.pdf).
