Hi,
Diagram is missing in converted PDF, for Windows as well as Linux.
Check these input/output files,
Aspose_Words_Diagram_Missing.zip (62.8 KB)
I did the simple exercise of selecting all the content and copying it into a new DOCX file that was not protected like yours and it works. So it seems there is an issue with shapes when there is a template directive that prevents edition on legacy documents.
This is my result when the document is not protected.
ShapesMissingOnDocumentWhenSavingPdf_input.docx (49.8 KB)
ShapesMissingOnDocumentWhenSavingPdf_output.docx (18.7 KB)
ShapesMissingOnDocumentWhenSavingPdf_output.pdf (73.5 KB)
The diagram is saved correctly into the DOCX and PDF files.
I will report a bug regarding this issue so the dev team can investigate this more in-depth.
