NAME
       ppmdim - dim a PPM image

SYNOPSIS
       ppmdim dimfactor [ppmfile]

DESCRIPTION
       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, noth-
       ing) to 1.0 (original picture's brightness).
