The FixPS program will now support multiple page landscape
output, fixing all of the landscape pages in the file.
Also, the program is now compatible with other PostScript utilities
in the Coyote Library, which means in addition to US letter
and European A4 page sizes, it now support US legal and
ledger page sizes as well. Because it *is* compatible, if
you use PS_Start and PS_End to configure and close the
PostScript device, then PostScript landscape mode output
is fixed automatically for you. You never have to think
about this again. (Except, of course, when ITTVIS gets
around to fixing the underlying problem. But I wouldn't
hold my breath.)
Making everything compatible involved small changes to
a number of files, listed here:
http://www.dfanning.com/programs/fsc_ps_setup__define.pro
http://www.dfanning.com/programs/fsc_psconfig__define.pro
http://www.dfanning.com/programs/fixps.pro
http://www.dfanning.com/programs/ps_start.pro
http://www.dfanning.com/programs/ps_end.pro
You can find all five of these PostScript utility files,
as well as a number of other Coyote Library files required
to run them, in this zip file:

/ENCAPSULATED works pretty well except for one annoying thing: it
doesn't place the Postscript 'showpage' command, so you can't actually
print the resulting .eps file. While it might have been the case that
in the stone ages, you weren't allowed to put 'showpage' in an
encapsulated PS file, that requirement hasn't existed for ~10-15
years.

When I started working with PS output, I took the advice to always
use /ENCAPSULATED and never both with the landscape/portrait fiasco. I
had actually assumed that advice came from David. Maybe it did!
Is there some case where you cannot use /ENCAPSULATED ?

The new article that describes the details of how to
modify your IDL PostScript landscape file to allow a
PostScript viewer to view the file right-side-up can
be found here:
http://www.dfanning.com/ps_tips/landscapeup.html
I have made a few significant changes in the FixPS
file already. Among them are these. (1) If an output
filename is not provided, the input PostScript file
is modified in place. (2) The program checks for
non-landscape mode files and files that have already
been modified, and leaves these files untouched.
You can find the file that implements the changes to the
file here:
http://www.dfanning.com/programs/fixps.pro
I have re-written parts of the code to eliminate any
dependence on the Coyote Library. I thought this might
make the file more useful to a larger audience.
At the moment, the program will only work with single
page landscape output. Perhaps if there is need, I will
upgrade it to multiple page landscape output as well.
Cheers,
David
