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; } }
