The problem is that PostScript (apparently) doesn't have a standard
for what "landscape" is suppose to be. For example, if you open these
files up in Ghostview and orient them as "seascape", they appear
correctly. There is a "Swap Landscape" button in Ghostview do to this
automatically. Here is what the documentation says about it:
******************************
When the Swap Landscape option is checked, GSview swaps the meaning of
Landscape and Seascape. Most of the Landscape documents that I have
encountered require a 90 clockwise rotation of the paper to view.
However, there is no standard and some documents need to be rotated the
other way. The Swap Landscape button allows GSview to automatically
rotate the document the right way in response to the %%Orientation
comment in the PostScript file.
********************************
In any case, everything I've ever put PostScript files in has the
ability to "flip" the image quickly. It doesn't seem to be much of
a problem.
You could try putting your own orientation comments into the PostScript
file with the OUTPUT keyword to the DEVICE command. Let us know if you
get something like that to work.
Cheers,
David

Dear S and David,
we have tried a lot of things to get idl output right rotated in landscape.
It's impossible at the moment, so we have done a feature request.
Some of us are working on a routine which will write the rotation postscript
command into the postscriptfile for each page.
It is not finished. Sometimes it works ...
One more feature of this routine is to set the right boundingbox for eps
files.

Don't know how to do this in IDL. It sure is annoying when all your
other programs think it should be oriented the other way. You didn't
say what your platform was... If you have the pstops command (common on
linux) you can say
pstops '0U(8.5in,11in)' infile.ps outfile.ps
There is probably a program on any platform to do something similar,
or you can write it yourself with the advice here:
http://www.physics.ohio-state.edu/~faqomatic/fom-serve/cache /140.html
I would use a hack like the one below to automate the rotation (type dclose
instead of device,/close to finish the file).

return, file
