gv clipping in landscape?!
Christian Sgraja
I have a problem displaying pages which are in landscape orientation
(e.g. slides made with latex and dvips). gv displays the ps-file
in landscape orientation, but clips the right side. The ps-file
prints fine, and the ps-code looks correct!
Duncan McEwan posted the same problem in June this year
(comp.lang.postscript) and reported the following:

I'm also getting this behaviour of gv...
Unfortunetly the REactions on Duncan's posting did not help
solving the problem :-( So the question is still open for me.
My configuration:
- Unix solaris 7
- gs 7.03
- gv 3.5.8
A sample file is here:

Thanx for any advice.

How did you generate the Postscript? Try running "dvips" with AND
without "-t landscape" to see if there are any differences. If using
A4, try also adding "-t a4". Try all combinations to see which works.
This is a bit black art, I think.
Also check the bounding box specification of your PS file with the
command "grep ^%%BoundingBox: postscript_file". Does it match the
orientation of the paper? For A4, it should say "0 0 842 595" or
something close (due to margins) for landscape.

Maybe, this is a problem with "gv"? I can view landscape without
problems with "gv". Does the old "ghostview" behave the same?
A last hack to try is to locate the "clip" operators in your
Postscript file, and replace them with "newpath" to see what happens.
If the result is still the same, then it should be something wrong
with "gv" and, less likely, Ghostscript. If this hack works, then
there is something wrong with the Postscript file. The program that
generated the Postscript (dvips?) would be the suspect. If you didn't
use "epsf" or "epsfig" or any Postscript specials in your LaTeX
manuscript, you can try to use "pdflatex" to generate a PDF file, and
then use a PDF utility (such as Acrobat's free Reader) to generate a
Postscript file. Does the problem go away? If so, blame "dvips", or
your inability to use the suitable (but tricky) options.
Since the Postscript can print on the printer, it is possible that it
is just the DSC comments that are fooling "gv" around. As the
printers ignore all DSC comments, they are unaffected. In this case,
the solution is to tell "gv" not to "respect document structure",
which is a toggle item on the "State" pull-down menu.
