Im can do the conversion.  No problems.    That is vector to Raster, and
that is what IM does.

However ALL converters (no just IM) will need info on what resolution or
density the postscript should be converted at.

If the postscript is written as vectors, the resolution to use is vital,
and converting at a higher resolution then shrinking using IM's resize
function, can make things look a lot better. 

ASIDE: IM's resize function has be proved much better when compared to
photoshop, See

However if the postscript itself is only a wrapper around a raster
image, than using a specific resolution may not extract the images
perfectly pixel to pixel.

This is where a non-simple 'image extraction' technique may be needed.



PEOPLE,  please send in your 'postscript image wrapper' solutions, and
we may be able to design a special  ps_image:  input format delegate.


Ghostscript may may have something to do this, I don't know.

Also to think about...
