Sarah Kelley commented on PDFBOX-1067:
--------------------------------------
I had kind of suspected that JBIG2 might be the issue; thus the reason I had
tried sticking an ImageIO compatible JBIG2 library in the classpath. It didn't
help. :-)
So, how difficult is it to add JBIG2 support using a third party library? If
it's difficult enough that it won't happen soon, would it be at least possible
to get some kind of warning message, or an exception thrown? Like the
"Unsupported Operation: ri" messages that some of my test files generate? At
least in the short term? The only reason I began to suspect JBIG2 was looking
through the PDF code and browsing Wikipedia; a simple "JBIG2 not currently
supported" error message somewhere would have been a big time saver. Quietly
rendering the entire page as black isn't nearly so informative...

> Key: PDFBOX-1067
> URL: https://issues.apache.org/jira/browse/PDFBOX-1067
> Project: PDFBox
> Issue Type: New Feature
> Components: PDModel
> Affects Versions: 1.6.0
> Environment: Tested on MacOS X 10.6.7, Ubuntu 10.10, Windows 7
> Reporter: Sarah Kelley
> Attachments: ItDoesntWorkScan.pdf, sakelley_pdf_rendering_problem.zip
>
>
> The file "ItDoesntWorkScan.pdf" renders to an empty
> black page. This file is a copy of "ItDoesntWorkPrinted.pdf"
> that has been printed on paper, and then scanned with
> a Xerox WorkCentre 5030 scanner, which then emails a pdf file
> back to the user.
> Tested On:
> - Mac OS 10.6
> - Windows 7
> - Ubuntu 10.10
> Unfortunately, the WorkCentre 5030 doesn't appear to have
> many user-settable options for scanning to PDF, so we weren't
> really able to try scanning with settings other than the defaults.
> Will attach pdf and code to demonstrate.
