[jira] [Created] (PDFBOX-4513) FDFAnnotationStamp fails to parse
some appearance streams
Kai Keggenhoff created PDFBOX-4513:
--------------------------------------
Summary: FDFAnnotationStamp fails to parse some appearance streams
Key: PDFBOX-4513
URL: https://issues.apache.org/jira/browse/PDFBOX-4513
Project: PDFBox
Issue Type: Bug
Components: PDModel
Affects Versions: 2.0.15
Environment: OpenJDK 1.8.0_201-2-redhat, Microsoft Windows 10
Reporter: Kai Keggenhoff
Attachments: bad_stamp-2.0.15.xfdf, bad_stamp2-2.0.15.xfdf
Some stamps still cause issues in 2.0.15 when their appearance streams are parsed.
I attached two XFDF files which produces this error when I merge it :
Apr 12, 2019 7:46:34 AM org.apache.pdfbox.util.Hex decodeHex
SCHWERWIEGEND: Can't parse
0, aborting decode

it looks like the attribute value contains a LF/CR. When this error occurs, the appearance is missing and only the outline of the stamp is shown when the user selects the element.
I found two of the default stamps in Adobe Reader (german version) to cause this
- SBNotForPublicRelease ("Nicht zur Veröffentlichung", bad-stamp-2.0.15.xfdf)
- SBPreliminaryResults ("Vorläufige Ergebnisse", bad-stamp2-2.0.15.xfdf)
