Thumbnails for MS Office?
LeaUK
Hi All
Having resolved my general thumbnail issue I'm now seeking guidance in how to create auto thumbnails for MS Office docs. I'm confused whether this feature is supported in Resourcespace or not. The wiki says it is, but perhaps my Office docs need to be generated with an inbuilt thumbnail/preview for this feature to function?
Any thoughts much welcomed.
Cheers
Lea

Maybe someone else can comment on what's available for Office conversion and thumbnails in Windows.

thumbnails embedded in the XML package, and that's how previews are
possible without additional software. But, at least in the Microsoft
Office XML formats (which most people probably don't use), I think you
have to turn on a preference to embed the thumbnail, and then the
preview is very small and not multi-page.
If you want really good multi-page Office Document support, you really
need to get unoconv working, and I've only seen this work on Linux.

If you really need to support Office Documents, you need unoconv, and
that means you probably need to run a Linux server.

Problem is as someone explained to me unoconv just executes an OpenOffice conversion behind the scenes and much as I like OpenOffice itself it's conversions of anything but simple MS Office docs can be woeful. Again as explained to me this is more a Microsoft issue as their Office specifications run to more than 7000 pages and interpreting them sucessfully is like sending a man to Mars in techical terms. An alternative to OpenOffice called LibreOffice is meant to be better and works with unoconv but I haven't got around to trying it yet.
The only other suggestion I have is somewhere in the group I read stuff a while back of someone getting some experimental (very early release) Windows conversion working but it did involve a lot of techy stuff. If I find it I'll let you know.

replacement for OpenOffice. To my knowledge it is not too different
from Open Office (LibreOffice was forked last year from OpenOffice
when Oracle bought OpenOffice via Sun and there were concerns about
it's future), but it would be interesting to compare output.
I don't have a lot of complex Office Documents, and I usually use and
recommend Open Office, so I haven't seen a lot of incompatibilities,
although I have seen a couple of instances where the Microsoft Office
and Open Office render a document differently enough that it was
irritating. I can remember this happening when I produced complex ODF
documents with tables (invoices) programmatically, saved them to a
Microsoft format via Open Office, so our offices could use their
Microsoft Products to edit them if necessary, which is where it got a
bit buggy.
Unconv is still the best solution available (next in line would be
qlpreview on mac).
Here's a nice page of reasons why Microsoft won't support a
server-side Office application. http://support.microsoft.com/kb/257757
Even if they did, the consequences would be pretty bad. You'd have to
either fork the processing of previews to a separate server (assuming
you want to use Linux but have to run an "Office Server" on Windows,
or host your whole RS application on Windows and miss out on the other
benefits of Linux) And it would likely be very expensive. For example,
to run InDesign on the server side, you have to pay something like
$15K+ depending on your usage, and it is illegal to try to script a
single normal InDesign application on the server-side.

Hi Guys
Tom Gleason
If not, then you need to change settings in your Microsoft programs to
embed thumbnails.
If the thumbnail does exist, it could be that the extraction process
isn't working the same on Windows.
Looking at the command in preview_preprocessing, it looks like it
probably wasn't designed to work on Windows, but maybe isn't that
difficult for someone with Windows skills to fix:
run_command("unzip -p $file \"docProps/thumbnail.jpeg\" > $target");

Thanks Tom, no thumbnail in folder docProps...and I've spent ages trying to find the option to enable this in Word 2007...not having a great day!

[David ARNOULT] Hi
I confirm this problem. As long as ther’s no emf support bu imagemagick on linux (licensed format , you can still try to use unoconv plugin+ open office to convert them to pdf. It works but not for all Word format.
