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 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
       resulting image.
