How to retain existing Acrobat/PDF version using Splitter class
Dear all,
In our use of the org.apache.pdfbox.util.Splitter class to split a PDF document according to top level bookmarks,
we have observed that the newly created documents do not retain the existing Acrobat/PDF version of the original document.
(Splitter#createNewDocument()).
Can experienced users/developers direct us to samples or other resources that show how this can be achieved?
We are required to preserve the version of the original.
This is a requirement of a downstream process that consumes the split documents.
For example, if the input PDF is in version Acrobat 6 (PDF 1.5), we would like the resulting split documents to be the same version.
Thank you for your help.
-K.M-Martin

Not any longer, as I've just fixed that in PDFBOX-2713 at least for the trunk ;-)

Hello Kristina,
can you try the attached patch to org.apache.pdfbox.multipdf.Splitter?
It should copy the PDF version of the source to the newly created documents.
Note that PDFBox always sets the version in the header to 1.4 and this
only updates the /Version entry in the Document Catalog. This should
be enough (at least it works with Adobe Reader).
Best
Martin
