Sorry about this post. I originally posted this message close to a year ago.
I have no idea where it came from again. I assume there was a server problem
on our end.

I took Guido's advise (way back then) and a just wrote my own TiffLib
module.

It works great and I couldn't have done it without Python!!!!!!!!!

The module not only creates Multi-Page Tiffs (MPT) out of Single-Page Tiffs
(SPT), but it has the ability to create what I call "Streaming Multi-Page
Tiffs".

The first version I wrote merely grabbed all of the SPT files, combined them
into a single MPT file, and stored it on magnetic. That took up too much
storage and was too limiting.

I rewrote it to have the option to stream the MPT back to the client without
storing a copy on magnetic.

The user can now select any range of pages (e.g. pages 50-60 out of 1037
pgs) to speed download and get just the pages they need. For some reason,
testing shows that the download time is consistently a few seconds faster if
the file is created on the fly than if it already existed and was just
downloaded (go figure?).

If you're curious, the application can be seen at

You'd have to drill down through "Advanced Search" and find a document to
get to the streaming.

...couldn't have done it without Python!!!!...

Later,
