Questions and postings pertaining to the usage of ImageMagick regardless of the interface. This includes the command-line utilities, as well as the C and C++ APIs. Usage questions are like "How do I use ImageMagick to create drop shadows?".
Old versions don't let you change the color with Strings ("none"), for example. See here: http://de.php.net/manual/de/function.im ... eimage.php
Perhaps you should try it with "new ImagickPixel('#00000000')" (or something like that - I don't use Imagick) in that line, too.
