SYNOPSIS
ppmdim dimfactor [ppmfile]


DESCRIPTION
This program is part of Netpbm.

This program is largely obsoleted by the more general pam-
func(usethe-multiplier option). ppmdim remains for backward com-
patibility and also because its use of integer arithmetic may make it
faster.

ppmdim reads a PPM image input. Diminishes its brightness by the spec-
ified dimfactor. The dimfactor may be in the range from 0.0 (total
blackness, deep night, nada, null, nothing) to 1.0 (original picture's
brightness).
