SYNOPSISppmdim 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 compatibilā
ity 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, nothing) to 1.0 (original picture's
brightness).
