PS and PDF Rendering Different
I use FOP to generate PDF files from XML data retrieved from a database.
The PDFs generate just fine. However, when I tell FOP to render postscript
the output file is often corrupt. When I print the ps file on my postscript
printer the header area on the second and following pages is all messed up.
That is, text is missing, strange text and shapes appear in their place and
the size of the header area is not the same as the first page. If I view
the ps file using GSView (GhostScript) I get the following message when I
attempt to open the file:
DSC Error
%%Pages: doesn't match number of %%Page:
GSView displays the ps file with the same errors I get if I print the ps
file directly to the printer. I am using FOP 0.20.2 on Windows (both NT and
2000) with JDK 1.3 from Sun. Any ideas what is wrong?
Thanks,

We're using Acrobat Reader 4.05 on Unix (Linux/Solaris). I've written a
little wrapper class that calls "acroread -toPostScript......" (as a
filter). For us, that's clearly an temporary solution until we can
invest some more time in the PostScript renderer especially, since
Acrobat takes up about 40% of the whole processing time of a single
document. No ideas on the figures with GhostScript. I'm only using it as
a viewer.

Good luck!

Jeremias,
Thank you for your honesty. I'm glad to know its not something we're doing.
As for using GhostScript, how did you integrate it into your Java
application? The Java application which does our rendering runs detached
(as a Windows service). This application runs non-stop, monitoring a
database. When it sees a row added to a table it generates a PDF. On an
average day this application will generate a couple thousand PDFs. So being
able to run GhostScript either within the Java application (preferred
approach) or as a daemon which would monitor a directory for the creating of
PDF files which it would then print would be a second option.
Thanks,
Jim

Sure, the PostScript renderer is far from being finished. :-) The
renderer still has problems with some fo constructs, fonts and even DSC
(as you mentioned). If you need good quality right now, you should use
Acrobat Reader on Unix or GhostScript to convert PDF to PS. That's what
I still do. Improving the PostScript renderer is still on my tasklist,
but I've got so much to do that it hasn't come to the top of the list,
yet. Sorry.
