-
- Our intent is to replace preview with code which hopefully will work in
- the same process as the document being edited. Ideally I would like to
- see the Postscript printing layout technology leveraged into a true
- WYSIWYG editor. (though I speak only for myself on that one as far as I
- know...) Another less lofty goal perhaps would be a dynamic preview.

- I disagree, one of the problems with ATK printing currently is that
- groff, and the varieties of troff are slightly different in many
- respects.
-
- Another drawback of hybrid ditroff/postscript printing is that it is not
- possible to include an inset which prints in troff in an inset which
- prints in postscript and have the printing work.
-
- Perhaps it may be worthwhile for us to investigate another text
- formatter besides troff...
-
- Minimum requirements:
- 1. Documents can include embedded postscript (following the spec for EPS)
- 2. Font metrics must be available to ATK apps. (so they can compute
- their print sizes)
- 3. It must be possible to format text TO embedded postscript (preferably
- computing preferred size), and subsequently include this in a document.
- (text or more raw postscript.)
-
- 1 is trivial. 2 could be accomplished with gross hackery giving ATK
- knowledge of the mapping of troff fonts to Postscript fonts, (currently
- we have the technology to read AFM files).
- As far as I know 3 is not feasible with ditroff or groff...
-
- Neither ditroff nor groff is so powerful that I believe we will have
- great difficulty duplicating the functionality in a direct ATK -> PS
- conversion.
-
- Ditroff/groff are unattractive also in that you have to pay, or you have
- to get and compile gcc (and g++ if gcc <2), and libg++. Having
- followed the groff route for the HP 9000/700 I can say it was pretty
- painful.
-
- If anyone has any comments, suggestions on this topic we would be happy
- to hear them :-)
