Not so bad as it sounds... The device who's output we were processing only used a subset of all that PS allows (basically only vector drawing strokes and fills, and some text - no embedded hex images or etc.) So mainly what I did was convert PS vector drawing commands into CGM vector drawing commands, and the mapping was not too bad. Of course, managing the PS stack (which has no real analogue in CGM) was a bit of a problem, and the text was a problem - no easy way to handle fonts embedded in the PS output, so I tended to just substitute CGM fonts in a rather haphazard way... This worked, and the stuff output (to the plotter) actually looked fine - nobody knew what a hack it was under the covers. But I do know I don't fancy doing any of that stuff again... -- Ian SELEX Galileo Ltd Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England & Wales.
