NAME

       pbmpscale - enlarge a PBM image with edge smoothing

SYNOPSIS

       pbmpscale N [pbmfile]

DESCRIPTION

       This program is part of Netpbm(1).

       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.

OPTIONS

       There  are  no  command line options defined specifically for pbmpscale, but it recognizes
       the options common to all programs based on libnetpbm (See
        Common Options ⟨index.html#commonoptions⟩ .)

NOTES

       pbmpscale works best for enlargements of 2. To do enlargements greater than 2, you  should
       do as many enlargements of 2 as possible, then enlarge by the remaining factor.
