Andreas Lehmkühler commented on PDFBOX-1067:
--------------------------------------------
I ran some more tests and I can confirm that the filter works. But there are
some other issues in the post process of the filter. The pdf attached to this
issue doesn't render because of the wrong index model in the PDPixelMap class.
Others are rendering fine with the same code. Furthermore those JBIG2-images
which are images mask seem to have another issue.
Nevertheless I'll commit the filter code soon and follow up with the remaining
issues.

> 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

> 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.
