This is a simple man page reading task.

'man ras2ps' gives you one of the option to do exactly what you want,

     -i   Invert the image.  This will reverse black and white on
          a  monochrome  image  and  is  of limited usefulness on
          color images.

Also see rash(1), rasterfile(5), rasfilter8to1(1).

Also try 'man -k raster', you might surprise yourself with some
unknown programs(to you) on your system.
