Subject [jira] [Issue Comment Deleted] (PDFBOX-4417) Merged file has several structure trees
Date Sun, 30 Dec 2018 04:14:00 GMT

     [ https://issues.apache.org/jira/browse/PDFBOX-4417?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tilman Hausherr updated PDFBOX-4417:
------------------------------------
    Comment: was deleted

(was: Possible explanation for the double StructTreeRoot is that when cloning, the root doesn't
exist in the cloner map. Thus it is cloned when accessed through the /P (parent) entries.

A possible solution that I'll think about is whether to add the ability to add elements to
the map of the cloner.)

> Something goes wrong with all the cloning. The result file has a StructTreeRoot at objects
8, 697 and 730. And there is also the "COSStream has been closed and cannot be read" exception
(PDFBOX-3999) if one closes the source before saving.
> If the close is removed the current tests pass, so the tests are not yet complete.
> Merging  [^001031.pdf] (file from FDA) with itself also brings an orphan check error.
> Merging  [^054080.pdf] (file also at https://pubs.usgs.gov/wdr/wdr-sc-04/wy04/pdfs/02148000.2004.sw.pdf
) with itself also shows two StructTreeRoot dictionaries (and no other failing test, despite
the commits related to  [^001031.pdf] ).
