----------------------------------
xpdf-filters.html to install works in certain formats and not others.
Conversion from pdf to html can work but certain editing abilities get removed.
see http://www.uk-mobile-phone.com
The thumbnail image does not load properly in such 3D documents and renders
a red cross rather than the desired imagery.
> XPDF support for filtering PDFs for text extraction/search.

> Project: DSpace 1.x
> Issue Type: Improvement
> Components: DSpace API
> Affects Versions: 1.5.1, 1.5.2
> Environment: Unix and Linux
> Reporter: Mark Diggory
> Assignee: Mark Diggory
> Fix For: 1.5.2
>
> Attachments: xpdf-filters.html, xpdf-filters.xml, XPDFFilters.patch

> Here are a pair of mediafilters to process PDF files with the
> XPDF suite (see http://www.foolabs.com/xpdf/ ) replacing the
> one based on PDFBox. They invoke an external command, which
> must be configured. It has been tested on Unix and the concept
> ought to work on Windows (and certainly on MacOS X).
> XPDF2Text is a replacement for the existing PDF media filter, it
> creates extracted text using the pdftotext program. I've observed it
> is about 3 times as fast, and much more reliable, than PDFBox.
> XPDF2Thumbnail creates a thumbnail image for the first page of
> the PDF. This is especially effective for 3D PDF renderings of
> engineering models, but works fine for any document.
> See the instructions in xpdf-filters.html to install it.
> The thumbnail filter needs an additional image library, but
> the text extractor doesn't need anything else.
> This code has been tested with DSpace 1.5.1
