I have the spreadsheet attached and all that I am trying to do is converting it into PDF. For some reason though, the page a shape/picture belongs to, seems to take precedence over the zorder when converting the Workbook into PDF.
new Workbook("test.xlsx").save("test.pdf", new PdfSaveOptions());
test.xlsx.zip (903.5 KB)
Outcome:
