       ppmdim - dim a portable pixmap down to total blackness

       ppmdim dimfactor [ppmfile]

       Reads  a  portable  pixmap  as input. Diminishes its brightness by the specified dimfactor
       down to total blackness.  The dimfactor may be in the range  from  0.0  (total  blackness,
       deep night, nada, null, nothing) to 1.0 (original picture's brightness).

       As  pnmgamma does not do the brightness correction in the way I wanted it, this small pro-
       gram was written.

       ppmdim is similar to ppmbrighten , but not exactly the same.
