NAME
       pnmarith - perform arithmetic on two PNM images


DESCRIPTION
       This program is part of Netpbm(1).

       Starting	   with	   Netpbm    10.3,    pnmarith	 is   obsolete.	   Use
       pamarith(1)instead.

       pamarith is backward compatible with pnmarith except where  your	 input
       images  have different depths.  pnmarith would convert the one with the
       lesser depth to have the higher	depth  before  doing  the  arithmetic.
       With pamarith, you must do that step separately, using pgmtoppm.
