Imagick

Image toolkit implementation based on ImageMagick. Unlike the ImageMagick module, which invokes convert binary to process images, this module uses the Imagick PHP extension. It allows custom effects that need to access image data such as Smart Crop.

Requirements

• The Imagick PHP extension should be installed on your server.

Consult your server administrator or hosting provider if you are unsure about these requirements.

Installation and configuration

• Install as usual, see https://drupal.org/documentation/install/modules-themes/modules-7 for further information.
• Go to Administration » Configuration » Media » Image toolkit and change the image toolkit to Imagick.
• Optional: Enable optimization to comply with Google PageSpeed guidelines.

Imagick Preview

Version 7.x-1.1 contains a effect preview module. This module will kick in when editing image effect settings. It will display preview images of the current effect and all effects in the image style combined.

ImageCache Actions

As from version 7.x-1.0 on we decided to remove ImageCache Actions from this module as a requirement for several image effects. The effects mentioned in the description are working and don't need any other module to be installed.
