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 proba
bly add a pnmsmooth step; otherwise, you can see the orig
inal pixels in the resulting image.
