Follow-up Comment #1, bug #37681 (project octave): The range of values for indexed images is dependent on their class and this may be the origin for confusion. If the indexed image is of an integer class, their indexes start at 0 so there's an offset of 1 for the colormap. However, some index images can be of class double in which case there's no offset and the minimum index should be 1. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?37681> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
