Coreldraw will allow you to export the previously imported HPGL file as
a bitmap (e.g. TIFF etc).
But my version (5) limits you to 4800x4800 pixels which is not good
enough for high-quality reproduction, because for text and line drawings
(as opposed to photos), you really need >1200dpi to get professional
magazine-quality reproduction. Ive come unstuck a number of times in
this area and the professional advice is to *avoid* bit-map graphics -
keep everything in vector form as far as you can.
This is a digression, but to illustrate the point...
Magazine publishers (or, at least, the ones that know what they are
doing) go spare if you send them a photo at, say 300dpi, with text
superimposed on it. They require the text separately, at a much higher
resolution).
And, slightly more to the point, I have heard that the editor of Descent
gets a bit weary of people sending him bit-mapped cave surveys that are
of a totally inadequate resolution!
