       This program is part of Netpbm(1).

       pbmpscale  reads  a  PBM  image  as input, and outputs a PBM image enlarged N times.  pbmpscale does this
       enlargement by pixel replication, with some additional smoothing of corners and edges.

       pbmpscale - enlarge a PBM image with edge smoothing

pbmpscale works best for enlargements of 2. To do enlargements greater than 2,  you  should  do  as  many
       enlargements of 2 as possible, then enlarge by the remaining factor.

       There are no command line options defined specifically for  pbmpscale,  but  it  recognizes  the  options
       common to all programs based on libnetpbm (See  Common Options .)
