PDF Viewing problem

mr_clark · 11-13-2011, 01:34 AM

Okay. So I upgraded my DXG to 3.2.1 firmware hoping it would fix my issue with some of my PDFs but it doesn't. I've found that some PDFs I subscribe to (Linux Journal being one of them) sometimes don't open on my Kindle. They just show one blank page and that's it. Is there something I can do to the PDFs to clean them up or fix them so they will open correctly?

It's weird because the October issue opened fine. The November one screws up.

Any suggestions would be greatly appreciated.

Thanks.

Try running it through pdftk, that'll often fix issues with pdf-files:
$ pdftk INPUT output OUTPUT

Multivalent repair / compress might also help. You'll need Multivalent20060102.jar, as the never jar does not support the command-line options.

Thanks Utnapishtim. That worked great. File went from 12MB to 18MB but at least I can view it on my Kindle now.

No problem.
If you want to save space, then try the Multivalent compress function (get the jar here). I've had PDFs that went from 24MB to less than 500kb:

$ java -cp Multivalent20060102.jar tool.pdf.Compress -jpeg -noalt -nostruct INPUT.pdf

This will save the output in INPUT-o.pdf, but you can use -inplace to simply overwrite the input file.
