NAME
       ppmdim - dim a PPM image


SYNOPSIS
       ppmdim dimfactor [ppmfile]


DESCRIPTION
       This program is part of Netpbm(1).

       This program is largely obsoleted by the more general pamfunc(1)(usethe-multiplier option).  ppmdim remains for
       backward compatibility and also because its use of integer arithmetic may make it faster.

       ppmdim reads a PPM image input. Diminishes its brightness by the specified dimfactor.  The dimfactor may be  in
       the range from 0.0 (total blackness, deep night, nada, null, nothing) to 1.0 (original picture's brightness).
