DESCRIPTION

       This program is part of Netpbm(1).

       pnmscale  was  obsoleted by pamscale(1),introducedwithNetpbm10.20 (Jan-
       uary 2004).  pamscale is backward compatible with pnmscale,  plus  adds
       many additional functions, including the ability to process PAM images,
       and tends to produce better results.

       pnmscale remains in the current Netpbm package because it probably  has
       fewer  bugs  for  now  than pamscale, and may have superior performance
       characteristics in some cases.  Some day, pnmscale will probably become
       an alias for pamscale.

       You  can  use  the pamscale documentation for pnmscale, considering the
       following differences:



       ·      pnmscale options are a subset of pamscale’s, as
                   documented above.

       ·      pnmscale always assumes the input is linear, as pamscale
                   does when you specify its -linear option.

       ·      pnmscale cannot process PAM images.
