Alan,

You can see what  I've got so far here:
https://github.com/jsnshrmn/DSpace/raw/master/dspace-api/src/main/java/org/dspace/app/mediafilter/XPDF2Thumbnail.java
Testing is definitely something it could use!

Jason,

To clarify, you sent Scott a solution for PDF thumbnails?  I'd be very
interested in testing it as well. :)  We're still testing XPDF and
Terry's Ghostscript solution for PDF thumbnails so I'd love to compare.

Cheers,

Alan

Re: [Dspace-tech] PDF Thumbnail Resolution

2013-11-26 Thread Alan Orth 
Terry,

That's very interesting.  I just tried your code and it works great, I
compared it to the XPDF method as well as our the manual thumbnailing
we've been using (embarassingly) for a few years[0].  The colors in the
PDF I used as an example are a bit exaggerated, but it's not too bad and
the thumbnail is much more crisp.

BTW, I made a pull request[1] on your repo to add some installation /
configuration instructions to your README.md.

Cheers!

Alan

 Sorry about the inaccurate first answer.

 I see that both the fixed JPEGFilter/BrandedPreviewJPEGFilter and your
 XPDF2Thumbnail use the awt libraries to manipulate bitmaps. Therefore
 it might be possible to apply the same fixes to XPDF2Thumbnail as were
 applied to the JPEG filters. Try asking Jason Sherman
  about it, he's the author of the fixes and might
 be willing to do it for PDF, too.

Re: [Dspace-tech] PDF Thumbnail Resolution

We had a similar need.  I created a module to build thumbnails with
ImageMagick and Ghost Script.

If this sounds useful, you can see the code here.

Yeah, that's the code I'm using. I'm not too surprised if the JPEG work is only 
for images- I would say the PDF thumbnails work is quite an obscure 
requirement. Anyway, if this is not changing, I would be happy to tell the

Not an immediate answer to the question, but I think the recent work on the 
JPEG filters only applies to images.

The XPDF code that generates thumbnails for PDFS can be found here:
