pnmenlarge(1)                          General Commands Manual                         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 en‐
       large  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.
