`Polycast_Filter_ImageSize`
===========================

[](#polycast_filter_imagesize)

> Zend Framework extension providing filter facilities for image size using different strategies.

Minimal example
---------------

[](#minimal-example)

```

```

Complex example
---------------

[](#complex-example)

- Crop the image instead of fit it into the bounding box.
- Output as JPEG (actually this is the same as above as it is the default)
- Set a specific output directory `(default = ./)`
- Use caching, i.e. override only if source image is newer than thumbnail (if exists)

\[markdown syntax is stupid\]

```

```

Humongous example
-----------------

[](#humongous-example)

```
class NamedConfig extends Polycast_Filter_ImageSize_Configuration_Standard
{
    protected $_templateName = null;

    public function __construct($templateName)
    {
        $this->_templateName = $templateName;
    }

    public function getTemplateName()
    {
        return $this->_templateName;
    }
}

class CustomPathBuilder implements Polycast_Filter_ImageSize_PathBuilder_Interface
{
    private $_outputDir = null;

    public function __construct($outputDir)
    {
        $this->_outputDir = $outputDir;
    }

    public function buildPath($filename, Polycast_Filter_ImageSize_Configuration_Interface $config)
    {
        $chunks = explode('.', strrev(basename($filename)), 2);
        $basename = strrev(array_pop($chunks));
        $ext = strrev(array_pop($chunks));

        switch($config->getOutputImageType()) {

            case 'jpeg': $ext = '.jpg'; break;
            case 'gif': $ext = '.gif'; break;
            case 'png': $ext = '.png'; break;

            case 'auto':
            case null:
            default:
                $ext = ".$ext";
        }

        if ($config instanceof NamedConfig) {
            $postfix = $config->getTemplateName();
        } else {
            $postfix = sprintf('%sx%s-q%s', $config->getWidth(), $config->getHeight(), $config->getQuality());
        }

        $path = sprintf('%s/%s-%s%s',
            $this->_outputDir,
            $basename,
            $postfix,
            $ext
        );

        return $path;
    }
}

$filter = new Polycast_Filter_ImageSize();
$config = $filter->getConfig();

$config = new NamedConfig('product-thumbnail-100x100');
$config
       ->setWidth(100)
       ->setHeight(100)
       ->setQuality(50)
       ->setStrategy(new Polycast_Filter_ImageSize_Strategy_Crop())
       ->setOverwriteMode(Polycast_Filter_ImageSize::OVERWRITE_ALL)
;

$filter->setConfig($config);
$filter->setOutputPathBuilder(new CustomPathBuilder('images/thumbnails/'));
$outputPath = $filter->filter('./rick.jpg');

```
