pnmenlarge(1)

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
   pbmreduce 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.
