I assume you talk about ACL on windows (from the other question). I dont
know anything about graphics on UNIX.
 
For a first and very easy approach to the problem I would use the printing
capabilities of Allegro. The printer is a stream which works like a graphics
device in MS Windows. You can use it almost like a window. And you install a
printer driver for a postscript printer and connect it to a file. From my
experience of generating "good" postscript from MS Word, I recommend using
the Apple LaserWriter II printer driver. These printers are bit old, but
printers and drivers were famous for having excellent postscript (almost as
good as dvips). "Good" postscript in the meaning of "well formed and valid"
postscript, which means you can use it later on anything which claims to be
able to handle postscript.

I've seen this several times myself. This does not happen in Windows NT. I
would recommend to set the optimization flags in ACL to some minimal values
(not to (speed 3) (debug 0) ) and stay away from anything like
without-interrupts. Things on Win98 get worse if you're using threads.

Subject: Postscript pictures???


Hi,
  I'm probably dreaming, but is there any possibility for easily generating
postscript (or other common formats) from a standard Allegro graphics
session?
  In short, is there any way for me to run my normal graphics code and just
send everything to a special type of stream (e.g. for a postscript file)
instead of my normal window stream?  
  Basically, I draw a lot of different types of diagrams in Allegro, and
it's kind of a pain to have to dump the data to files and then redraw them
in another language (like MATLAB) to get nice print-outs.
  I'm using Allegro 5.01 or thereabouts.
 
One other question:
 
I've asked this several times, but the suggested solution never works:
 
  When running Allegro in Windows 98, I can't find a way to break my run
without terminating Allegro itself.  This has become a real pain recently,
since I'm debugging some pretty hairy code which frequently goes into
hyperspace.  I have no problem halting stuff in Unix, but in Windows, the
usual use of the Break key just isn't enough.  I have to do cntl-alt-break
to get any interrupt, and then my only option is to kill lisp itself.
 
Cheers...
