NAME
        ppmdim - dim a portable pixmap down to total blackness
 
SYNOPSIS
        ppmdim dimfactor [ppmfile]
 
DESCRIPTION
        Reads  a  portable pixmap as input. Diminishes its bright­
        ness by the specified dimfactor down to  total  blackness.
        The  dimfactor  may be in the range from 0.0 (total black­
        ness, 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.
