## 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  pn-
       msmooth step; otherwise, you can see the original pixels in the result-
       ing image.
