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       Starting with Netpbm 10.3, pnmarith is obsolete.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.
