Dan,
I'm glad this may work for you. As far as the speed: it's of course
difficult to judge, and I certainly didn't test it under any real load,
but I had no problems creating and serving a several page document with
graphics in it. We were testing the concept of something like this for
a system with a non-public system, so weren't overlly concerned about
testing the efficiency of this, especially since this wasn't to be our
final approach. I'd be interested if you find out more information on
the subject.
On using passthru: I do not think FOP has the option to passthru the
PDF output from the command line call. It was necessary to save the
generated PDF and then serve it. (I haven't double checked, but I think
I saved the file because I had to.) Of course FOP is open source so you
have the opportunity to make it work with you.
