Usage & Documentation

This extension is a wrapper to the Imagine and also adds the most common methods used for Image manipulation.

To use this extension, you can use it in to ways, whether you configure it on your application file or you use it directly.

The following shows how to use it via application configuration file:

// configuring on your application configuration file
'components' => [
    'image' => [
        'class' => 'yii\imagine\Image',
        'driver' => \yii\imagine\Image::DRIVER_GD2,
    ]
    ...
]

// Once configured you can access to the extension like this:
$img = Yii::$app->image->thumb('path/to/image.jpg', 120, 120);

This is how to use it directly:

use yii\imagine\Image;

$image = new Image();
$img = $image->thumb('path/to/image.jpg', 120, 120);

About the methods
Each method returns an instance to \Imagine\Image\ManipulatorInterface, that means that you can easily make use of the methods included in the Imagine library:

// frame, rotate and save an image 

Yii::$app->image->frame('path/to/image.jpg', 5, '666', 0)
    ->rotate(-8)
    ->save('path/to/destination/image.jpg', ['quality' => 50]);
