description

Reads a portable bitmap as input, and outputs a portable bitmap enlarged N times. Enlargement is done by pixel replication, with some additional smoothing of corners and edges.

notes

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.
