ImageMagick

Allows to use ImageMagick or GraphicsMagick as image toolkit for Image API in Drupal 7 and 8 core. This integration is based on invoking the convert binary through shell access to process images. The Imagick module is an alternative toolkit module that uses the Imagick PHP extension instead.

Requirements

• ImageMagick needs to be installed on your server and the convert binary needs to be accessible and executable from PHP.
• The PHP configuration must allow invocation of proc_open() (which is security-wise identical to exec()).

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

Note: GraphicsMagick, a performance fork of ImageMagick (like Pressflow to Drupal) should work as well. Just replace the convert executable with gm in the image toolkit settings.

Installation

• Versions 7.x and 8.x-1.x: Install as usual, see installing contributed modules for further information.
• Versions 8.x-2.x: The module requires using Composer to manage Drupal site dependencies. Require the module via
  

  $ composer require drupal/imagemagick:~2.0
  

  then enable the module as usual.

Configuration

• Go to Administration » Configuration » Media » Image toolkit and change the image toolkit to ImageMagick.
• If the convert binary cannot be found in the default shell path, you need to enter the full path to ImageMagick's convert executable.

ImageMagick integration for Drupal evolved through many different projects and developers in the past, and most of the code wouldn't exist without the efforts of:

• James Walker (walkah)
• Darrel O'Pry (dopry)
• Andrew Morton (drewish)
• Dan Morrison (dman)
• Nathan Haug (quicksketch)

Notes on ImageMagick for Drupal 8

The module provides an image toolkit that has 'feature parity' with core's GD toolkit: it includes the framework for integrating ImageMagick to the Image API, and the corresponding image toolkit operations (create_new, convert, crop, desaturate, resize, rotate, scale, scale_and_crop).

By default, the toolkit supports the same image formats of the GD toolkit (GIF, JPEG, PNG). However, it can be configured to manage any of the image formats that ImageMagick or GraphicsMagick binaries support (like e.g. TIFF, SVG, WEBP, BMP, etc.), through image toolkit's configuration admin UI.

Image effects (Automatic Orientation based on Exif, Strip Metadata) and image toolkit operations (auto_orient, sharpen, strip, watermark) that were part of the advanced module in the Drupal 7 version, have been ported to the Image Effects module.
