[sane-devel] Avision AV8300 Support for 11x17in Document Size

[Tom Garvin]

This solution worked on my development system, but now I'm having a
similar issue with the production system.  While they're both running
the same version of SANE (backend=*.18, frontend=*.14), the option no
longer seems to work.  If I run 'scanadf -h' without the force-a3 entry,
I see that my height is limited to 420.  But when I add the entry to the
avision.conf file, the height is actual decreased to 419 (instead of
increased to 432 (as it did on my first system).

I think I've controlled for other variables in my testing... so I'm not
sure what to do next.  I searched for duplicate avision.conf files on
the problem system, but I'm sure it's finding this file because when I
add the force-a3 entry, I do see a change... but like I said, it's -1
instead of +12.

Any ideas?
