There seems to be a few issues with Imagick in PECL related to setting your own properties on a class that extends Imagick. A project I’m working on at the moment is making heavy use of image processing and I wanted to stick with Imagick over the GD library. A little bit of investigation told me that this bug was fixed in the latest release candidate of Imagick in PECL, so I began investigating how to install a beta release of the extension but Google gave me no hits.
