ANNOUNCEMENT --- ASCREEN 3.1
============================
I'm pleased to announce that ASCREEN 3.1 is now available for anonymous
FTP.
ASCREEN 3.1 is a GEM-based DVI screen previewer for the Atari ST/TT
series of computers. Its features include
*** SPEED: One of the fastest previewers available for the Atari.
*** CONVENIENCE: Depending on how much memory is available, formatted
pages are cached for later retrieval (You can cache about 8 normal-sized
pages on a 1MB ST. With a 4MB ST or a TT, the sky's the limit). Memory
usage can be deliberately limited so other programs won't be crammed in.
While you are looking at one page, a unique `cache-ahead' feature
formats the next one. You can open as many windows as GEM will let you
have, and look at several pages or various parts of the same page all at
once. You can also shrink pages to check their overall layout. ASCREEN
3.1 can be controlled by mouse or by keyboard, and keyboard commands can
be changed to suit your preferences.
*** COMPATIBILITY: ASCREEN 3.1 is completely GEM-based and should be
able to take advantage of any graphics hardware that supports GEM. It
has been tested on various configurations ranging from an Atari 520ST
with a SM124 monitor to an Atari TT driving a TTM195 hi-res monochrome
display. No known dependencies on the TOS version exist (checked against
1.0, 1.02, 1.04, 3.16).
ASCREEN 3.1 fits neatly into most implementations of TeX on the ST. You
can even go on using your native previewer's fonts since ASCREEN lets
you configure its resolution and font naming scheme. ASCREEN supports
graphics \special commands of Christoph Strunk's csTeX as well as Stefan
Lindner's CTeX for the ST. ASCREEN also supports packed font libraries
in emTeX's FLIB format.
ASCREEN 3.1 can be called from the GEM desktop, from any command line
shell that can start GEM applications, or from leading TeX shells like
Christoph Strunk's `cTeX' or the `TeXshell' by Kiessling, Heidrich and
Maluschka.
ASCREEN 3.1 works together with PAM's MultiGEM, too: you can even set up
your TeX system so that ASCREEN will automatically re-display the
current DVI file after a TeX run.
*** CUSTOMIZABILITY: Defaults for most settings can be specified in a
configuration file. Any one of several configuration files can be
selected from the command line or loaded from the menu bar while the
program is running. The defaults may be overridden from the command
line, and there are dialog boxes available as well. At any instant, a
snapshot of the current settings may be saved to another configuration
file. Items that can be customized include:
- path names for DVI files, fonts and graphics files
- font resolution and naming
- minimum page dimensions
- memory management parameters: number of pages cached,
size of font management arena
- DVI buffering parameters
- diverse switches controlling program behavior
*** INTERNATIONALIZATION: ASCREEN 3.1 comes with German and English user
interfaces. Adding yet another language is as simple as editing one of
the enclosed resource files. You can even use ASCREEN in various
languages on the same computer: just assign the name of the appropriate
resource file to a special environment variable.
You can get and use ASCREEN 3.1 for free. You may also redistribute it
if you don't make any money off it or pretend that you wrote it.
ASCREEN 3.1 is available for anonymous FTP from
ftp.math.uni-frankfurt.de [141.2.90.2], directory pub/atari.
*Please note that this site is in Germany, Europe, and retrieve the
software only at off-peak times, that is, 1800-0800 hours CET (UT+0100),
or during the weekend.*
There is a mailing list for announcements, bug reports, comments,
questions and general discussion about ASCREEN; send mail to
`ascreen-request@math.uni-frankfurt.de' to subscribe or to find out
more.
