Well, it doesn't have to be intimidating. All you need is
the appropriate image coordinate system, which you could
get in the most trivial case by drawing a set of axes around
the image. A task that is made trivial, by the way, by most of
the substitute TV commands available on the Internet. Once the data
coordinate system is established, conversion is quick and
easy with CONVERT_COORD.

Cheers,

David
