Try IDRISI. It works great for all kinds of Raster operations and analysis and
has a lot or options for boolean and matimatical operations with images.

>
> Dear Listers,
>
> I'm searching for a raster processing tool that could do
> an OR operation on two raster images.
> Both images are identical size in pixels and are
> BW bitmap.
>
> I'd like the software to compare the images pixel by
> pixel and make a new image according to OR rule :
> black OR black = black
> black OR white = black
> white OR black = black
> white OR white = white.
>
> Batch processing would also come in handy.
