Currently Intervention Image supports two Image processing extensions. Make sure you have one of these installed in your PHP environment, before you start.
You're able to configure Intervention Image to use one of these libraries for all its operations. Just pass the configuration as an array directly into the ImageManager.
// include composer autoload require 'vendor/autoload.php'; // import the Intervention Image Manager Class use Intervention\Image\ImageManager; // create an image manager instance with favored driver $manager = new ImageManager(['driver' => 'imagick']); // to finally create image instances $image = $manager->make('public/foo.jpg')->resize(300, 200);
You might also use the static version of ImageManager as shown in the example below.
// include composer autoload require 'vendor/autoload.php'; // import the Intervention Image Manager Class use Intervention\Image\ImageManagerStatic as Image; // configure with favored image driver (gd by default) Image::configure(['driver' => 'imagick']); // and you are ready to go ... $image = Image::make('public/foo.jpg')->resize(300, 200);
Image manipulation in PHP is a very memory consuming task. Since most tasks in PHP don't exhaust default memory limits, you have to make sure your PHP configuration is able to allocate enough memory to handle large images.
The following php.ini directives are important.
Sets a maximum amount of memory in bytes that a script is allowed to allocate. Resizing a 3000 x 2000 pixel image to 300 x 200 may take up to 32MB memory.
If you're planing to upload large images, verify that this setting for the maximum size of file uploads fits your needs.

It's possible to set these directives in your php.ini or at runtime with ini_set.
If you're using Laravel, you can pull a configuration file into your application by running the following artisan command.
$ php artisan vendor:publish
$ php artisan config:publish intervention/image
In Laravel 5 applications the configuration file is copied to
config/image.php, in older Laravel 4 applications you will find the file at
app/config/packages/intervention/image/config.php. With this copy you can alter the image driver settings for you application locally and define which library should be used by all commands..
'driver' => 'imagick'
