Dave Smith commented on PDFBOX-1067:
------------------------------------
After some more digging I found an example where the do not use the globals. So
we should check for that.
Replace
reader.setInput(ImageIO.createImageInputStream(JBIG2StreamMerge(st.getFilteredStream(),compressedData)));
With..
if(st != null)
{
reader.setInput(ImageIO.createImageInputStream(JBIG2StreamMerge(st.getFilteredStream(),compressedData)));
}
else
{
reader.setInput(ImageIO.createImageInputStream(compressedData));
}

> 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
> Labels: JBIG2
> Attachments: ItDoesntWorkScan.jbig2, 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.
