Imagine adapter
===============

The rendering engine for media is able to use different imagine adapters. By default the bundle detects the installed
adapters and uses the most mature implementation by default.

Available adapters are:

* `gd`_
* `imagick_extension`_
* `vips_extension`_

GD

The simplest adapter is GD and it has no external dependencies besides the PHP extension.
