This means that the GraphicsMagick configuration you have on you system will limit what your Octave installation can do. Most systems will have it on their own repositories. Unfortunately, their configuration is not always the best for image analysis as it limits reading of images to 8-bit. | ||
To solve the problem, GraphicsMagick needs to be rebuilt with the appropriate seetings. See below for tracking dependencies and the reasoning behind each flag. Once done, the following commands should work to build GraphicsMagick. | |||

These other dependendies are easily added via a user-editable text file after building and installation. They are much more specific and most users will have no need for them. | These other dependendies are easily added via a user-editable text file after building and installation.
