                 bytscl(z)

              or bytscl(z, top=max_byte, cmin=lower_cutoff, cmax=upper_cutoff)

         returns a char array of the same shape as Z, with values linearly
         scaled to the range 0 to one less than the current palette size.
         If MAX_BYTE is specified, the scaled values will run from 0 to
         MAX_BYTE instead.
         If LOWER_CUTOFF and/or UPPER_CUTOFF are specified, Z values outside
         this range are mapped to the cutoff value; otherwise the linear
         scaling maps the extreme values of Z to 0 and MAX_BYTE.
