pbmpscale N [pbmfile]

This program is part of Netpbm.

pbmpscale reads a PBM image as input, and outputs a PBM image enlarged
N times. pbmpscale does this enlargement by pixel replication, with
some additional smoothing of corners and edges.

pbmpscale works best for enlargements of 2. Enlargements greater than
2 should be done by as many enlargements of 2 as possible, followed by
an enlargement by the remaining factor.
