## NAME
       pbmpscale - enlarge a PBM image with edge smoothing


## SYNOPSIS
       **pbmpscale _**N_ [_pbmfile_]


## DESCRIPTION
       This program is part of [**Netpbm**(1)](https://www.chedong.com/phpMan.php/man/Netpbm/1/markdown).

       **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) .)

       as many enlargements of 2 as possible, then enlarge by the remaining factor.
