Using PDF.js to render Headers for Screen Reader Softwares (NVDA, JAWS)

[aadiola]

Hi, everyone!

We're trying to support Headings detection in our Document Viewer. We want something like this:

For performance reasons, we only render 2-3 pages at a time. While we can use the getTextContent() method to extract the text layer, we're unsure how to make the screen readers support the reading of headings for the entire document.

Has anyone tried this on their projects?

Any help would much appreciated!
