Tilman Hausherr created FOP-3365:
------------------------------------
Summary: /StructureTreeRoot/ParentTreeNextKey is missing in
accessible PDF output file
Key: FOP-3365
URL: https://issues.apache.org/jira/browse/FOP-3365
Project: FOP
Issue Type: Bug
Components: renderer/pdf
Affects Versions: 2.12
Reporter: Tilman Hausherr
Attachments: fop.pdf
Out of curiosity I've been looking at the PDF file generated by
{{testMultipleStaticContentArtifact()}} and ran one of the PDFBox tests on it
(you need the PDFMergerUtilityTest code in the PDFBox project).
{code:java}
try (PDDocument doc = Loader.loadPDF(file))
{
PDStructureTreeRoot structureTreeRoot =
doc.getDocumentCatalog().getStructureTreeRoot();
if (structureTreeRoot != null && structureTreeRoot.getParentTree()
!= null)
{
checkWithNumberTree(doc);
checkForPageOrphans(doc);
Map<String, PDStructureElement> idTreeMap =
Collections.emptyMap();
PDNameTreeNode<PDStructureElement> idTree =
structureTreeRoot.getIDTree();
if (idTree != null)
{
idTreeMap = idTree.getTreeAsMap();
}
checkForIDTreeOrphans(doc.getPages(), idTreeMap);
}
}
checkStructTreeRootCount(file);
{code}
/StructureTreeRoot/ParentTreeNextKey (the next available free key) is missing
and should be 2 for the attached file, because keys 0 and 1 are used.
