-------------------------------------------------------------------------

                 Key: PDFBOX-795
                 URL: https://issues.apache.org/jira/browse/PDFBOX-795
             Project: PDFBox
          Issue Type: Test
          Components: PDModel
    Affects Versions: 1.2.1
            Reporter: Dan Sabin
         Attachments: b.pdf, b.png

Converting a PDPage to an image results in an image file only being partially generated.  Some text at the top of the file is created, but the majority of the page is not and an exception is thrown:
[ERROR] java.io.IOException: Unknown stream filter:COSName{JBIG2Decode}

Is JBIG2Decode not a supported COSStream encoding?
