NAME
       pnmenlarge - read a portable anymap and enlarge it N times

SYNOPSIS
       pnmenlarge N [pnmfile]

DESCRIPTION
       Reads  a  portable anymap as input.  Replicates its pixels N times, and
       produces a portable anymap as output.

       pnmenlarge can only enlarge by integer factors.  The  slower  but  more
       general pnmscale can enlarge or reduce by arbitrary factors, and pbmre‐
       duce can reduce by integer factors, but only for bitmaps.

       If you enlarge by a factor of 3 or more,  you  should  probably  add  a
       pnmsmooth  step;  otherwise,  you  can  see  the original pixels in the
       resulting image.
