I trying to parse page tree of PDF specification (ISO).
It seems that there are two page tree nodes with Parent pointing to each other.
Here is parser output:
DocumentCatalog: /MarkInfo /Marked true/Metadata 3304 0/Names 124349 0/OpenAction [124334 0 /XYZ null null null ]/Outlines 124355 0/PageLabels 124243 0/PageMode /UseOutlines/Pages 124246 0/StructTreeRoot 7665 0/Type /Catalog Page node 124246 0: /Count 6/Kids [1953 0 2009 0 2035 0 2037 0 2039 0 2041 0 ]/Parent 124324 0/Type /Pages Page node 124324 0: /Count 10/Kids [84 0 86 0 88 0 90 0 92 0 94 0 96 0 100 0 102 0 104 0 ]/Parent 124247 0/Type /Pages Page node 124247 0: /Count 10/Kids [1792 0 1795 0 1808 0 1817 0 1829 0 1834 0 1849 0 1857 0 1862 0 1909 0 ]/Parent 124324 0/Type /Pages Is that valid??? How should I handle it?
