ppmdim(1)


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.
