Image

Kohana 3.x provides a simple yet powerful image manipulation module. The Image module provides features that allows your application to resize images, crop, rotate, flip and many more.

Drivers

Image module ships with Image_GD driver which requires GD extension enabled in your PHP installation, and Image_Imagick driver which requires the imagick PHP extension. Additional drivers can be created by extending the Image class.

The Image_GD driver is the default. You can change this by providing an image.default_driver configuration option - for example:

// application/config/image.php
<?php
return array(
    'default_driver' => 'Imagick'
);

Older versions of Kohana allowed you to configure the driver with the Image::$default_driver static variable in the bootstrap, an extension class, or elsewhere. That variable is now deprecated and will be ignored if you set a config value.

Getting Started

Before using the image module, we must enable it first on APPPATH/bootstrap.php:

Kohana::modules(array(
    ...
    'image' => MODPATH.'image',  // Image manipulation
    ...
));
