Support tagged content in PDF exports for accessible heading structure #3199
Description
Describe the Bug
I am a blind user of Bookstack. Using it in general works fine. There is one thing though I have noticed.
When exporting a page to a PDF-File, the heading-structure set in the editor is not seen by the screenreader. It appears that the tags used to provide this kind of information to assistive technologies is isregarded during the export process.
It would help a great deal if the formating is preserved during exports to PDF. That ensures that the exported PDF-Files can be read and efficiently navigated by all people.
Thank you for taking the time to fix this. I'll gladly provide more info if necessary.
Steps to Reproduce
- open a page in bookstack which has at least one heading.
- export the page as PDF.
- Open the PDF
- Using PDF-testing-tools of choice see that the heading(s) are just enlarged text and not tagged as headings.
Expected Behaviour
the exported PDF-File should preserve formating in an accessible way.
