bin-packer
==========

[](#bin-packer)

I made it for a metal cutting company. This code selects the appropriate raw metal sheets for cutting. Original idea Padam87 link: 2D bin packing for PHP, with rotation.

Usage
-----

[](#usage)

### Basic

[](#basic)

```
$Boxes = [
    new Block(100, 100),
    new Block(300, 100),
];
$bin = new Bin(1500,3000);
$bin->insertManyBlock($Boxes);
```

#### How to get unused Boxes

[](#how-to-get-unused-boxes)

You will get all unused Block as a array.

```
$unusedBoxes = $bestBin->getUnpackedBlocks()
```

### How to get used boxes

[](#how-to-get-used-boxes)

You can get the node tree and evaluate it with a function

```
    $node = $bin->getNode();
    getUsedBlock($node);

    function getUsedBlock(\Node $node)
    {
        if($node == null)
            return;
        if($node->isUsed())
        {
            print_r($node->getBlock());
            $this->getUsedBlock($node->getRight());
            $this->getUsedBlock($node->getDown());
        }
    }
```

### How to get score

[](#how-to-get-score)

```
    $sc = $bestBin->getStatistic();

Array
(
    [score] => 0.72624 // [used] / ([binWidth]*[binHeight])
    [used] => 2269500  // used arrea
    [free] => 855500   // free arrea
    [binWidth] => 2500
    [binHeight] => 1250
)
```

### Visualiser

[](#visualiser)

```
        $visualizer = new Visualizer();
        $image = $visualizer->visualize($bin);
        $image->setFormat('jpg');
        $image->writeImage('bin.jpg');
```
