Dave Smith commented on PDFBOX-1067:
------------------------------------
OK after looking at PDF File ItDoesntWorkScan.pdf the jbig2-imagio works
perfectly. The problem is in page object there is a /Rotate 270 that
org.apache.pdfbox.util.operator.pagedrawer.Invoke.process(PDFOperator operator,
List<COSBase> arguments) seems to be ignoring and thus rendering only the
white bit.
I pulled the jbig2 image out of the pdf and have attached it.
Here is the jbig2-imagio stub to convert the pulled image to a png. You will
note the rotation of the image is 270 degrees.
public class JBig2Spike
{
public static void main(String[] args)
throws Exception
{
ImageIO.scanForPlugins();
Iterator<ImageReader> readers =
ImageIO.getImageReadersByFormatName("JBIG2");
ImageReader reader = readers.next();
reader.setInput(ImageIO.createImageInputStream(new
FileInputStream("ItDoesntWorkScan.jbig2")));
BufferedImage bi = reader.read(0);
FileOutputStream out = new
FileOutputStream("ItDoesntWorkScan.png");
ImageIO.write(bi, "png", out); //$NON-NLS-1$
out.close();
System.exit(0);
}
}

> 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.
