[comp.windows.news] Display POSTSCRIPT to be available on DECwindows

	DISPLAY POSTSCRIPT(tm) SOFTWARE TO BE AVAILABLE ON DECWINDOWS(tm)
	      Adobe Systems and Digital Equipment Sign Contract

Mountain View, California (January 12, 1988) -- Adobe Systems
Incorporated and Digital Equipment Corporation have announced the
integration of Display POSTSCRIPT software into Digital Equipment's
DECwindows workstation architecture.  Adobe Systems and Digital
Equipment Corporation have signed a contract for Digital Equipment to
license Adobe's Display POSTSCRIPT software.

The DECwindows program is intended to provide users with
network-transparent application programming interfaces for windowing,
graphics and user interface services for its systems running under the
VMS(tm), ULTRIX(tm) and MS-DOS(tm) operating systems.  The DECwindows
architecture is based on the X Window System(tm) developed at the
Massachusetts Institute of Technology.

Based on the same imaging model used in POSTSCRIPT(R)-equipped
printers, the Display POSTSCRIPT system is a graphics software
component developed by ADobe Systems.  Display POSTSCRIPT software
brings the same graphics imaging power to computer displays as
POSTSCRIPT software brings to printers and typesetters.

"Simply stated, our objective is to bring to interactive displays the
same high level of functionality and portability, as well as device
independence, that we have provided in electronic printing," said Dr.
Charles Geschke, Executive Vice President and COO, Adobe Systems.

The result of the Adobe and Digital effort will provide application
developers with a programming interface to the complete range of
POSTSCRIPT's powerful graphic and font capabilities for the DECwindows
environment.  The Display POSTSCRIPT X Windows extension will be a full
implementation of the POSTSCRIPT language and will be completely
compatible with the printer version.  The extension will enable
application developers to use a windowing system to manipulate windows
and use POSTSCRIPT software to create their images within a window in a
fully device-independent manner.

Adobe first announced its intention to develop Display POSTSCRIPT
system technology in January, 1987.  As with POSTSCRIPT software for
printers, Adobe will offer the Display POSTSCRIPT system on a licensing
rights basis to computer and workstation manufacturers.  Today's
announcement is the second Display POSTSCRIPT licensing agreement
disclosed publicly by Adobe Systems.  In September, NeXT, Inc.
announced plans to incorporate the Display POSTSCRIPT system into their
workstation architecture.

Digital Equipment Corporation, headquartered in Maynard, Massachusetts,
is the world's leading manufacturer of networked computer systems and
associated peripheral equipment, and the leader in systems integration
with its networks, communications, software, and service products.

Adobe Systems Incorporated was founded in December, 1982 by Dr. John
Warnock and Dr. Charles Geschke.  Adobe is best known as the developer
of POSTSCRIPT, the page description language prominent in an increasing
number of printing devices.  To date, over twenty major computer,
printer and typesetter manufacturers have signed POSTSCRIPT software
licensing agreements with Adobe Systems.

Incorporated, P.O. Box 7900, Mountain View, CA  94039.  (415)961-4400.

Does this mean that if DECWindows and/or Display Postscript catch on
Sun will be forced to announce a new "merged NeWS, X, Display Postscript"
to conform to de facto standards?

Well, since Display PostScript isn't a window server, that's not really
what they'd have to do.  And given that Display PostScript is OUTPUT ONLY, 
I bet it wouldn't be that hard to replace the imaging code in NeWS with 
DPS without seriously changing the lightweight process stuff or the 
PostScript-based input and event-handling mechanisms.

[Perhaps this is common knowledge...but somehow I've missed it.]

A better question is....how does display postscript handle the window manager
functionality?  A recent non technical blurb I saw (I think from DEC) said 
display postscript just does handles the output model and doesn't provide 
for input or window manager functions.

It's easy to see how DEC might just stick a display Postscript interpreter
into a normal X window display but how is Next Inc. going to make it work?

why bother?  I guess I would be interested in knowing what Display 
Postscript can do that NeWS can't.  My understanding is that it is
forced to live in the native window system, single-tasking, no 
networking... is this correct?  I suppose the allure is if you use
X...but wouldn't this slow down X even more than it is now?

Any info would be appreciated.

Isn't stuff like this supposed to be in comp.newprod ???

The imaging code in NeWS release 1.1 is full PostScript much as Adobe
would like you to believe otherwise.  Only three primitives are missing:
currentscreen, setscreen, and settransfer all of which have to do with
half-toning which isn't terribly interesting on a screen (especially 
a color screen).  These primitives will almost certainly be in the
X11/NeWS merge.

But what about extensions?  The full range of extensions Abobe is planning
for Display PostScript isn't clear yet.  They have announced a compressed
binary format which I'm sure Sun will adopt in place of the one already
in NeWS 1.1.  They've also announced a function call library interface
to PostScript which should work just as well on NeWS as on Display PostScript.
They've also indicated the areas of some other extensions.  The extensions
will be very small in number and I'm sure Sun will go for compatibility
where it makes sense.

In summary, Display PostScript does not need to be "merged" with X11/NeWS.
Only a few minor changes will be needed to NeWS to make it compatible with
Display PostScript.
