incorrect PDF?:
I'm attempting to edit a scanned into PDF format and open it in
LibreOffice but keep getting an error "General Input/Output Error". I
have opened other PDF documents and been able to edit them (some
required password).

LibreOffice 3.5.4.2
Xsane 0.998
openSuSE 12.2-M3
KDE 4.8.1
Scanner: Brother MFC-J6710DW via wired network

I've looked in /var/logs but been unable to find anything related. I
have been able to work around this problem by opening the PDF in
Inkscape and using a text overlay but that isn't a very nice solution.

Does anyone have a comment or suggestion of how to get this PDF into a
usable format? Is this a known problem with Xsane's exporting? So far
I haven't been able to find it with Google.

Thanks, Tom

Should add that the PDF in question opens in xpdf from console but can't be
edited in that program.

Tom,

XSane will be exporting it as an image in a pdf document, not as text. XSane
does not do OCR. If you want to be able to edit the text you'll need to run it
through an OCR program, but that will not preserve the document formatting -
you'll end up with plain text.

I'm not aware of of any way that you can scan a document as an image, export
it as a formatted pdf and then be able to edit it. Not with free software,
anyway.

Yes, xsane inserts the scanned stuff into the pdf as an image.

However there is cuneiform/yagf pair, an OCR and its GUI frontend, and it works
pretty well, and available for openSUSE. It can save the text as plain text
(unformatted), and in html format, which keeps some formatting (headers, bold,
maybe font size).
