No, These have only two levels of brightness. Any gray-scaling you see in
such an image is due to dithering of pixels. There are kludgy ways of
reconstructing this but the quality would be bad. You could for example draw
the image onto a 24bpp bitmap and shrink it. The pixels would become
averaged and you may be able to reconstruct something. The problem would be
that you'd have to shrink it at least to 1/8th of it's size.
I don't think you'll get much success extracting information from this
format.
