test case
(In reply to novalazy+freedesktop from comment #0) > However, Table 322 of PDF 32000-1 > states that the K entry hold a dictionary representing a single structure > element. That is for the general Logical Structure. Tagged PDF imposes additional restrictions. In section 14.8.4.2: "In a tagged PDF document, the structure tree shall contain a single top-level element; that is, the structure tree root (identified by the StructTreeRoot entry in the document catalogue) shall have only one child in its K (kids) array." Thanks for the reference. I wonder if that is just bad wording, or the true intention of the spec writers. Many (possibly most) of the tagged PDFs I have come across suffer this problem, including those in the PDF/UA-1 reference suite. You can close this bug. I'm not opposed to removing the check. Even if it is against the spec it is effectively the same as a single element array containing a dict. Adrian did you include that fix/workaround in the patches of bug 103912 ? Would make sense to do that? I've pushed out the fix as it a trivial change. |
