ppmdim - dim a PPM image

       Copyright (C) 1993 by Frank Neumann

       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).

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