Someone here at Agfa Compugraphic recently pointed out how regressive
it was that our computerized discussions of PostScript were limited to
text. After all, more of us have access to PostScript displays (NeWS, Next)
every day. We got talking about the idea of a newsgroup where the
messages were sent in PostScript. This would allow posters to include
graphics, and even images, in their entries. Each reader would need an
interpreter suitable for his workstation. For example, vt100 users would
need a filter which just extracted the strings from the 'show's and displayed
them as text, while NeWS users could send the PostScript right to their
screens. Access to the display filter would be similar to the way that
'rn' displays rot13 articles.
Let's start a discussion about the feasibility and
desirability of this concept.

Corel Draw, for example, doesn't use ANY "show"'s to display text, because it (almost) always uses its own fonts.

Sounds like a neat idea to me. But a lot of poor souls must still read news on a plain old terminal. Most of them would loose all their graphics. Also, previews tend to be rather expensive in terms of a Workstation, disk space, CPU time, etc. Still, I think this is a neat idea.

[] Before embracing this concept, I would strongly urge people to consider the flap which erupted on (I believe) comp.protocols.tcp-ip after a couple of RFC's were posted in PostScript rather than in plain text. Some of the objections raised were: The PostScript form of a document is typically many times larger than the plaintext form. Relatively few readers have on-line PostScript browsers, so that PostScript articles can be read only by first converting them to hardcopy. Not everyone who wants to read the subject matter has a PostScript printer. Meaningful computer-assisted searching (e.g. grep) of saved PostScript documents is difficult if not impossible. Quoting is even worse. To which I might add: John Hascall's 12-line program required over 3 minutes to print on a LaserWriter II NT. Many of us spend too much time on news as it is.

I think it's a good idea. I'd even work on the NeXT software to do it.

This was typed in from an article in the current "TypeWorld" newspaper. Vol XIII, No 20, Second October 1989 issue, first page. See and learn PostScript on Mac Concord, MA -- A PostScript interpreter that runs on a Macintosh Plus, SE, or II and displays output pages on the screen is now being delivered by Lincoln & Co. PostShow, as the software system is called, is totally self contained and requires no printer or other hardware to operate. Like PS Tutor, the company's earlier IBM PC [boo hiss -cbc] product, PostShow is intended for the graphics arts professional who works directly with the PostScript language, as well as for the learner. PostScript files created by publishing and illustration software may be interpreted and viewed; such files can also be created or modified using the system's built-in editor. The interactive mode of PostScript is active and available so that commands can be executed from the keyboard. Assisting the programmer are features such as an online reference manual that describes all of PostScript's operators and error messages, pull-down windows into the operand stack and graphics state, and a "zoom-and-pan" function that permits any part of the page to be viewed, magnified, or reduced. PostShow incorporates the Macintosh user interface. PostShow produces hardcopy output on both PostScript and non-PostScript printers. On non-PostScript units, it prints PostScript pages at the screen resolution of 72 dots per inch. With PostScript printers, it transmits the PostScript files for interpretation by the printer. An introductory price of $224.95 includes the 13 standard PostScript fonts, similar in appearance and spacing to the Helvetica, Courier, and Times families, and to Symbol. An additional set of fonts, LWM22, is available for $69.95 ($89.95 when purchased separately from PostShow), contains 22 additional fonts that closely resemble those of more recent laser printers.
