You can create your own combinations of image transformations and save them as a custom Image Modifier class. This modifier defines which command, in which order and with which arguments should be called on an image instance.

Intervention Image provides the simple Intervention\Image\Interfaces\ModifierInterface, which all modifiers need to implement.

Once you have created your own modifier, you can apply them by using the modify() method.

Custom modifier implementation

Take a look at this very basic example of a custom modifier class, which combines a greyscale/pixelate effect.

use Intervention\Image\Interfaces\ModifierInterface;
use Intervention\Image\Interfaces\ImageInterface;

class MyCustomModifier implements ModifierInterface
    protected $size;

    public function __construct(int $size)
        $this->size = $size;

    public function apply(ImageInterface $image): ImageInterface

        return $image;

Applying custom modifiers

Once the custom modifier is implemented, you can easily apply it to an image instance.

public Image::modify(ModifierInterface $modifier): ImageInterface


Name Type Description
modifier Intervention\Image\Interfaces\ModifierInterface Modifier object


use Intervention\Image\ImageManager;

// create new image instance
$image = (new ImageManager('imagick'))

// apply modifier
$image->apply(new MyCustomModifier(25));
