Keynote Thumbnails?

[Mike Patterson <pa...@gmail.com>]

Hi,

I'm working on a project that requires I extract information from Keynote
presentations. In addition to text, I also need to extract (or generate) an
image representation of each slide.

I understand that Tika accomplishes the text portion of this project today.
I'm curious however, given the familiarity with the keynote file format, if
anyone has any suggestions for extracting/generating larger thumbnail
images from these presentations (images the size of what is shown in
Apple's Preview application). I know so much as that keynote embeds a
thumbnail for the slides in the file, however from the documents I've
inspected, this thumbnail is way too small.

Any suggestions would be greatly appreciated.

Thanks,
Mike

Alfresco has code to do just that, I'd suggest you take a look there:
http://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/repository/source/java/org/alfresco/repo/content/transform/AppleIWorksContentTransformer.java

(The unit tests + unit test sample files might help you as well, but the 
code's fairly straightforward)
