John Hewson commented on PDFBOX-2423:
-------------------------------------
This latest commit is quite large and will need some regression testing, as
I've replaced all the existing page tree code which we had in PDPageNode and
PDPage, along with the code for resource and content stream lookup in
PDFStreamEngine. I expect some bugs, but fixing them should be straightforward.
> Page tree handling needs rewriting
> ----------------------------------
>
> Key: PDFBOX-2423
> URL: https://issues.apache.org/jira/browse/PDFBOX-2423
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 1.8.7, 2.0.0
> Reporter: John Hewson
> Assignee: John Hewson
> Priority: Blocker
> Fix For: 2.0.0
>
>
> The way in which PDFBox handles the Page tree needs to be rewritten,
> preferably from scratch. Currently the document catalog returns the raw
> objects from the page tree, wrapped in either a PDPage or PDPageNode.
> We need to abstract over the page tree and get rid of PDPageNode, we should
> provide methods which can add/remove PDPage objects *only*. The existing
> low-level access to the page tree is not needed at the PD-level.
> Inheritance of page properties such as crop box, resources, and rotation
> should be reimplemented to use whatever new page tree abstraction we invent.
> We can finally remove the old broken methods which didn't look up the
> inheritance tree when retrieving these values.
