I have produced dozens if not hundreds of PostScript files (plots,
diagrams, etc.) with the same Fortran program. They look fine when
viewed with ghostscript or when printed out or when embedded in a LaTeX document. In TWO cases I've notived that after converting them to PDF
with ghostview, PDF viewers show them rotated by 90 degrees.

Any ideas?

The PostScript files are probably not 100% perfect (though they are
generally well written and compact), but good enough for what I need
(with those two exceptions).

Any ideas?

What are the bounding boxes? Check for coordinates that are zero or negative, or unusual aspect ratio.

Check for "inadvertent" setting of "best orientation", "size to fit", etc.

Run an extra ps2ps with explicit specification of orientation of output media.

Run ghostview (ghostscript: /usr/bin/gs) under valgrind.

That's not it. All are standard plots, roughly the same size, and so
on.

Nope.

Will have to try that.

Why use Ghostview to create the PDF rather than using Ghostscript
directly ?

Apart from any other considerations, GSView (I'm assuming that's what
you mean by ghostview) doesn't work with recent versions of Ghostscript
which means you're locked to an old version, with bugs and security
issues.

Anyway, the 'most likely' explanation is that the majority of the text
is horizontal when the page is rotated. You need to set - dAutoRotatePages=false to prevent that.

Sorry, typo; I converted with ghostscript.

I'm using GV, which IIRC is the result of some fork, on VMS. Yes, it
works only for older stuff. I have a newer ghostscript.

Interesting idea. However, it is a plot and the only text are the axis labels, one letter each.

Well to be perfectly honest, that wasn't at all clear.

I could sit here and throw out ideas only for you to shoot them down, or
you could just put an example file somewhere I could look at it. Or if
you think there's a bug you could open a bug report.

Would like to post here, but even the smallest file is too big for my
NNTP server. Will come back when I have time to set up a link etc.
