NAME

6       ppmdim - dim a PPM image

SYNOPSIS

10       ppmdim dimfactor [ppmfile]
11
12

DESCRIPTION

14       This program is part of Netpbm(1).
15
16       This   program   is   largely   obsoleted  by  the  more  general  pam‐
17       func(1)(usethe-multiplier option).  ppmdim remains for backward compat‐
18       ibility  and  also  because  its  use of integer arithmetic may make it
19       faster.
20
21       ppmdim reads a PPM image input. Diminishes its brightness by the speci‐
22       fied  dimfactor.   The  dimfactor  may  be in the range from 0.0 (total
23       blackness, deep night, nada, null, nothing) to 1.0 (original  picture's
24       brightness).
