       pamenlarge - Enlarge a Netpbm image N times

       pamenlarge N [pnmfile]

       This program is part of Netpbm(1).

       pamenlarge reads a Netpbm image as input, replicates its pixels N times, and produces a Netpbm image as output.
       The output is the same type of image as the input.

       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.

       pamenlarge  can enlarge only by integer factors.  The slower but more general pamscale can enlarge or reduce by
       arbitrary factors.  pamscale allows you to enlarge by resampling, which gives you smoother  enlargements.   But
       it is much slower.

       pamstretch  is another enlarging program that enlarges by integer factors.  It does a simple kind of resampling
       that gives you a smoothed enlargement with less computational cost.

       pbmreduce can reduce by integer factors, but only for PBM images.

       pamenlarge was new in Netpbm 10.25 (October 2004).  It is designed as  a  replacement  for  pnmenlarge  by  Jef
       Poskanzer,  which  was in Pbmplus as far back as 1989.  The major difference is that pamenlarge can enlarge PAM
       format images in addition to PNM.
