File Content Extraction 25.4
Filter SDK .NET Programming Guide

# Tagged Content - PDF

A tagged PDF contains an additional layer of text for visually impaired readers. This text is used in text-to-speech features in various PDF viewing programs. You can enable filtering of tagged PDF text in the API.

Filtering the extra layer of tagged content might result in duplicate text in the output. This is the expected behavior.

To filter tagged PDF content

- In the .NET API, call the method `TaggedPdfContent` on your session configuration. For example:

      session.Config().TaggedPdfContent(true);
