DESCRIPTION

14       This program is part of Netpbm(1).
15
16       pbmpscale  reads a PBM image as input, and outputs a PBM image enlarged
17       N times.  pbmpscale does this enlargement by  pixel  replication,  with
18       some additional smoothing of corners and edges.

NOTES

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