Yes, QuantumDepth=16 means 64 bits per pixel. It seems the octave programmers who wrote the warning warning: your version of GraphicsMagick limits images to 16 bits per pixel didn't understand this either. Even Daniel wrote "most display devices only support 8 bits per pixel anyway". That would be 256 colors, which is indeed a bit substandard. The question is whether the octave programmers misunderstood this only in their warning text or also in the octave code. -- Martin ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
