NAME

       ppmdim - dim a portable pixmap down to total blackness

SYNOPSIS

       ppmdim dimfactor [ppmfile]

DESCRIPTION

       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
       program was written.

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