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.
