INT8 and INT8ARRAY used to be signed values but these types were changed to unsigned a few versions back in the development version of GIMP. They are still signed entities in the 2.2 series of GIMP so storing values > 127 will read back as negatives. Aref doesn't return negative values in the current development version of GIMP (built from SVN). -- Cheers! Kevin. http://www.ve3syb.ca/ |"What are we going to do today, Borg?"
