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 pbm-
       reduce 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.
