       pbmpscale - enlarge a PBM image with edge smoothing


       pbmpscale N [pbmfile]


       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 works best for enlargements of 2. Enlargements greater than 2
       should be done by as many enlargements of 2 as possible, followed by an
       enlargement by the remaining factor.
