there is no such image format. once you commit something to a given
number of pixels, there is no going back. in the same way, you cannot
get a higher resolution from your sceen by using a microscope. the
only way to get what you want would be to re-render the data on
demand, i.e. by using VMD or a raytracing program.
the next best thing is to render the image at a much higher
resolution, i.e. with more pixels (i.e. like using a higher resolution
screen in my example above).
that requires that you use a rendering program, e.g. Tachyon, to
generate the image and change the flags that define the resolution of
the resulting image.
