This is because Octave.app was compiled with GraphicsMagick support disabled. If you want a version of Octave linked to GraphicsMagick you can either compile it yourself or install MacPorts <http://www.macports.org/> and install Octave via MacPorts <https://trac.macports.org/browser/trunk/dports/math/octave-devel/Portfile>. c. ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
