Huge thanks Tilman I’m still learning this stuff. But I did debug the loading of the image PDF, paying close attention to the structure tree. The more I dug in, the more I started to think this was a PDF output issue from Excel. But the spec is large, complex, and obscure in places. So I was still uncertain.
The Cross Reference table view in the PDFDebugger fairly plainly shows StructTreeRoot, ParentTree (in StructTreeRoot) and page content. And it’s plain there’s discrepancies. Allowable by the spec? No idea.
