----------------------------------
Summary: Problem with calling "saveIncrementalForExternalSigning"
more than once in the same document
Key: PDFBOX-3811
URL: https://issues.apache.org/jira/browse/PDFBOX-3811
Project: PDFBox
Issue Type: Bug
Components: Signing
Affects Versions: 2.0.6
Environment: Java 1.8
Reporter: Le Duc Duy
Attachments: PDFBoxTest.java, Screen Shot 2017-05-26 at 6.39.10 PM.png
I've included the test which will fail.
After digging around a little, I found out that by calling
saveIncrementalForExternalSigning, it trimmed the reserved space in the
ByteRange (I've included the difference in the screen shot).
I'm not sure if this is a bug for anyone but it's for my use case (distributed
digital signing). Changing the content at all is not permitted at all.
If this is an intended feature, please dismiss this. I can workaround by
calling it more than once and it'll be stable although I'm not sure about
efficiency.
