Image Filters in Intervention Image give you the useful possibility to group image transformations commands into a dedicated object. This object defines which command, in which order and with which arguments should be called on an image instance.
Intervention Image provides the basic Intervention\Image\Filters\FilterInterface
, which all filters need to implement.
Once you have created your own filters, you can apply them using the filter() method.
// init new image instance
$img = Image::make('foo.jpg');
// apply filter
$img->filter(new DemoFilter(45));
Take a look at the example of the DemoFilter src/Intervention/Image/Filters/DemoFilter.php
which combines a greyscale/pixelate effect.
<?php
namespace Intervention\Image\Filters;
class DemoFilter implements FilterInterface
{
/**
* Default size of filter effects
*/
const DEFAULT_SIZE = 10;
/**
* Size of filter effects
*
* @var integer
*/
private $size;
/**
* Creates new instance of filter
*
* @param integer $size
*/
public function __construct($size = null)
{
$this->size = is_numeric($size) ? intval($size) : self::DEFAULT_SIZE;
}
/**
* Applies filter effects to given image
*
* @param Intervention\Image\Image $image
* @return Intervention\Image\Image
*/
public function applyFilter(\Intervention\Image\Image $image)
{
$image->pixelate($this->size);
$image->greyscale();
return $image;
}
}
