pnmenlarge N [pnmfile]
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
pnmsmooth step; otherwise, you can see the original pixels in the
pbmreduce(1), pnmscale(1), pnmsmooth(1), pnm(5)
