Thanks Martin, I admit I never though to look what info was available
in the ArtWorks SDK as I've not looked at the documentation from it
for many years.
I did export a few very simple examples, just to see if the idea was
going to be even feasible.

That all seems straight forward.

OK.

I'm surprised deep sprites are not supported, that's a shame. CMYK
sprites would have been handy! But JPEGs being there helps. Although
I've just tried a JPEG within a clipview and it gives me an error of:
Internal error: abort on data transfer. But I'll try that again
another time, after a reboot and investigate some more.
Thanks Martin for all the info, much appreciated.
Gavin.
