When I export a Presentation to PDF and I have the “Tagged PDF (add document structure)” option selected The Images do not seem to have alternate text in the PDF output.
I have set the Image Name as well as the Image Description with both Title and Description fields completed and alternate text is not in the PDF created.
For Tables in a Presentation, the PDF Tags created are Paragraph tags and not Table Tags even though I set the table to have a Header Row. It seems like Table Structure is not preserved.
