Continuing search for postscript interpreter

OK, if you can't find what you want, you lower your sights and try again.

It appears nobody has a postscript interpreter that will drive a Versatec
7444 plotter directly. OK, I can do the back end.

Does anyone know of a postscript interpreter (commercial is OK, I don't
think there are any free ones) that can produce a raw bitmap, or something
similar that I can decode? It must have the following attributes:

1) Must be able to handle a 44" by 86" by 400dpi raster image.

2) Must do "pro" quality text (i.e. make full use of font hinting).

I prefer something that runs on VAX/VMS, but will consider all other
platforms.

I know about ghostscript, but it doesn't do font hints and is thus not
good enough. I know about CAI, and am talking to them. I also know about
NeWSPrint on a Sun, and am talking to them also. I'd like to be able
to evaluate other alternatives as well. Also, I'd really like to find a
VAX/VMS solution, as it would save me having to deal with multiple OS's,
multiple networking technologies, and all those other hassles that run up
the price and make configuring it non-trivial.

Quote:>[requirements for a postscript interpreter]

I'm getting a few of the same questions on my requirements from several
people, so I thought I'd post a bit more info.

Quote:>1) Must be able to handle a 44" by 86" by 400dpi raster image.

First, this is black and white only, graphics and text, fairly sparse
compared to a lot of applications (if you've ever seen our patterns, there
is quite a bit of white space there).

Second, it is a minimum. What I'd  really like is 44" by 106", which is
what I do now. I could reduce it to 86" fairly easily, anything below that
is difficult.

Quote:>2) Must do "pro" quality text (i.e. make full use of font hinting).

I have to do text as small as 6 point at arbitrary sizes and _rotations_.
I've been told this is a pretty demanding requirement. Of course I don't
care if hints or something else is used, but the text has to look good under
those conditions (remember, that's 6 point at 400 dpi, which is about
equivalent to 8 point at 300 dpi, as far as the difficulty of doing it).

Quote:>I prefer something that runs on VAX/VMS, but will consider all other
>platforms.

My preferences are VMS, DEC unix machine, other unix machine, anything else,
in that order. Don't be shy, I'll consider anything. (No flames please, I
only said DEC unix because they've gone to some trouble to make it easy to
use them with VMS, and the fewer hassles I have to deal with (like another
vendor), the more I like it; this is only a small part of my current
project, and I don't have time to make a career out of solving it).

You can use the ScriptWorks interpreter from:
        Harlequin Limited
        Barrington Hall
        Barrington
        Cambridge
        England CB2 5RG
;phone[+44 223-872522]

when used with the DFI laser amp interface (from:
        DFI, Ltd.
        DFI House
        Folly Gate
        Okehampton
        Devon  EX20 3AF
        ENGLAND
;phone[+44 (0837) 52055]
;fax[+44 (0837) 52462]
)

the interpeter can dump bitmaps for a page - which the memory mapped
laser printer prints. I have see this used for A4 and B3 sized pages
with several different engines. There is no reason that the program
can not generate larger bitmaps. You can also tell the interpreter to
simply dump the bitmap to a file - which is very easy to output on
what ever device you want [it is certainly easy to output to a
Versatec].

I should have indicated in my earlier posting that the Harlequin
interpreter runs on a number of boxes - but I have seen it running on
the SUN3, SUN4, and SUN386i [it seems to take about 1 day to port the
code to a new machine if there is a C compiler]. Harlequin needs to
have access to the machine for porting.

two CGM parsers/converters/viewers available:

    unix.hensa.ac.uk:/pub/misc/netlib/tarlibs/ralcgm/ralcgm-3.30.tar.Z
    ftp.psc.edu:/pub/gall/gplot.tar.Z

None of them support the full ISO-8632:1992 standard, and both have errors,
but they should manage most CGM files.
I *think* there's source for at least one of these.
