!!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.
