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) (use the -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 and 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).

OPTIONS
       There are no command line options defined specifically for ppmdim, but it recognizes the options common to  all	pro‐
       grams based on libnetpbm (See  Common Options .)

SEE ALSO
