The Image Library for Laravel: Intervention

Intervention Image is an open source PHP image handling and manipulation library. It provides an easy way to manipulate images. In addition, it integrates tightly with Laravel.

Installation

1. Install package

> composer require intervention/image

2. Integration with Laravel: becoming a Service Provider

Add the following lines into Laravel config file config/app.php. it will be added into the $providers array, which is the service providers for this package.

config/app.php

'providers' => [
      :
      :
   /*
    * Package Service Providers...
    */    
   Intervention\Image\ImageServiceProvider::class,
],

3. Add the facade of this package to the $aliases array.

config/app.php

'aliases' => [
      :
      :
  'Image' => Intervention\Image\Facades\Image::class,
],  

Now the Image Class will be auto-loaded by Laravel.
