ImageMagick Engine

What difference does it make?

ImageMagick can result in huge improvements in the quality of re-sized images.

Take a look at the supplied screenshot, or try it yourself.

Note that the new images tend to be slightly larger than those of the standard GD library, especially if you specify a very high image quality (95+).

How do I know if I have ImageMagick installed?

If you have the PHP module installed the plugin will find it. You can check yourself using the phpinfo() function. We also automatically check a common location for the ImageMagick executable.

If you have shell access to a Linux/UNIX server you can use “which convert” to look for the ImageMagick executable.

How do I install ImageMagick?

You’ll need full access to your server and a bit of technical know-how. If you do not have access you’ll have to ask the server administrator.

Don’t do it yourself unless you know what you are doing.

Most Linux distributions have a package for “ImageMagick”. Some have a package for “php5-imagick”. It is possible to install the PHP module using PEAR.

You can also find binary releases at http://www.imagemagick.org including a Windows installer.
