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

OPTIONS

       There  are  no command line options defined specifically for ppmdim, but it recognizes the
       options common to all programs based on libnetpbm (See
        Common Options ⟨index.html#commonoptions⟩ .)

SEE ALSO
