Subject: ghostview 1.3 running with ghostscript 2.5.2
Organization: GNUs Not Usenet
Distribution: gnu
Date: Tue, 6 Oct 1992 12:25:31 GMT

Hello,

Our platform is a 486 running Unix SVR4.

We have previously been able to run ghostview 1.3 with ghostscript 2.4.2.
We have recently built ghostscript 2.5.2.

When running ghostview with ghostscript 2.5.2, ghostscript seems to receive
something unexpected.

The error message is:

    Unrecoverable error: undefined in execute0
    Operand stack:
        --nostringval--
    Unrecoverable error, exit code 1


This happens with any postscript file.  Does anyone have any ideas about
what might be wrong?  Any help would be greatly appreciated.

          Thanks,
          Gina

Summary: Can't write driver using the above.
Organization: University of Texas Center for Relativity
Distribution: gnu
Date: Mon, 5 Oct 1992 05:34:43 GMT

Hi,

I have been trying for quite some time to get Ghostscript to produce
REAL 2 and 4 bit images for a bitmapped driver I have written. No matter
what I try, Ghostscript refuses to stick 2 or 4 pixels in each byte of
the image it produces. I have been told that GS is capable of this, but
I sure can't figure out how.  Can anyone PLEASE give me a clue about
what is required to twist Ghostscript's arm in this matter.

It appears to me that calling gdev_mem_device_for_bits(4) and setting
the elements of the color_info structure to the appropriate 4-bit color
values (mainly depth=4) should be all that is necessary, but I can't get
it to work. All of this is done when the device is opened, after the
driver figures out what hardware it must write to. I have checked that
the proper routines are being called (mem_mapped4_copy_mono for
example), but I can make no sense out of the bitmap that GS produces.
For speed and memory reasons, I need to access the bitmap directly,
rather than through the higher level GS routines which return scan lines
one at a time.

By the way, the driver has it's own map_color_rgb and map_rgb_color
routines, which appear to be working correctly. Any help will be greatly
appreciated.

Does anybody know if the Canon clc10 Color copier with the IPU unit is
compatible with bj10e color printer. All the manuals with the copier are
infested with BJ's and therefore I am if I could use Ghostscript to
rasterize for the color copier. We got Freedom of press Postscript
interpreter but only for PC and Mac, but becouse we only have slow PCs
and Macs(one simple picture takes 30 min) we would like to use our faster
workstations to print quicker without paying 250$ for Freedom of press
for Sparc.

I managed to get gs241 to make bj10e output but I dont have any idea on
how to get it out trough the SCSI bus. But if anyone could confirm this
it might be worth the effort to learn how to make a SCSI driver. Better
still if anyone is already using a setup like this it would be great to
know.

Thanks in advance for any info on that copier.

As the title suggest, since I loaded Gswin.exe 2.5.2 and the accompanied
files for it, when I attempt to run it in Windows 3.1 (Enhanced mode),
it appears to start loading for a moment and then flips right out. Tried
loading several times, but for a brief moment, it says something about not
initializing for 256? Now, Gswin.exe for 2.5.1 worked with its accompanied
files, but this version won't. My windows setup is for 800x600x16.
Can anyone suggest what is suddenly happening in 2.5.2 that didn't in 2.5.1?

Many people have reported problems with gcc 2.2.2 on the SPARC.  I
strongly suggest that you use some other compiler to compile
Ghostscript.

2.4 used a 16x16 pixel ordered dither on all devices.  This did not
seem appropriate for printers, where single pixels often overlap, so
I changed it to a 45-degree, 45 DPI spot dither.  You can change it
back by finding the line in gs that reads
	dup 150 lt systemdict /DITHERPPI known not and
and changing it to
	true

Halftone screens are an area where I don't have much experience.  I
would appreciate getting in touch with someone experienced who can
help me improve Ghostscript in this area.

Try changing the string near the top of the gs_init.ps file that
reads "252" to "251".  I think the GSWIN.EXE binary is still looking
for a version 2.5.1 init file.  This fixed the problem for me.  Note,
howver that this will create the same problem for the DOS binaries
GS386.EXE, etc. because they correctly look for the "252" string.

Good luck,

The program GSWIN.EXE contained in the archive GS252WIN.ZIP on Simtel and
mirror sites is not compatible with the Ghostscript 2.5.2 release.  It
expects the file gs_init.ps to have a reference to 2.5.1 in it and therefore
must be from the 2.5.1 release.  It will run properly if the "252" string
near the top of the gs_init.ps file is changed to "251".  The DOS versions
require the string to be "252", however.

Start by upgrading to 2.5.2.  And use a file transfer program that

Use the eps9high device; that's exactly what it's for.  I'm sorry it
isn't documented better.

Subject: gs problems w/ gcc 2.2.2 -O2
Organization: Smithsonian Astrophysical Observatory, Cambridge, MA,  USA
Distribution: gnu
Date: Fri, 2 Oct 1992 19:52:36 GMT

configuration: Sparc IPC, SunOS 4.1.1, gcc 2.2.2, gs 2.5.2, X11R5

when compiling ghostscript with gcc 2.2.2, use of the -O2 option
causes glitches when displaying the `chess.ps' example using the
X driver.  compiling with -O works fine. 

the error is that the chess pieces are "smeared" out to the left.
the smearing always occurs, but varies in form and extent with
each invocation of gs.  sometimes long streaks of black appear.

this is possibly a gcc bug, but i don't know enough about gs to pinpoint
which routine(s) are affected and thus make this determination.

Re <9210011802.AA14500@cookie-crisp>
<1992Sep30.195200.4963@tamsun.tamu.edu>, reporting a problem with the
Ghostscript Epson driver:

As I learned to my dismay over the course of several years, there is
no useful definition of "Epson-compatible."  Every "Epson-compatible"
printer has a slightly different command set; the intersection is so
small as to be almost useless.

If you have a very old and/or feeble Epson printer that can't set tab
stops (which is the mechanism Ghostscript uses, since I found out
that the more efficient command for horizontal skipping isn't always
available), you can recompile the Epson driver so that it never tries
to do this.  Just look for the comment "Skip a run of leading 0s" and
change the condition in the immediately following `if' statement to a
constant 0.

If enough people (3 or more) ask me for it, I can put in a
dynamically settable property that will cause the Epson driver not to
use tabs.  This won't happen before release 2.6, which is scheduled
for January.
