Can I use PDFNet to inspect tags in tagged PDF documents?


Does PDFNet support tagged documents? Can we use PDFTron .NET classes
to identify if a PDF document is a tagged document? If so can we
examine these tags?

The same API will be available as part of the upcoming .NET release. A

Using Cos/SDF API it is possible to edit existing logical structure or
to create new tags. We will most likely add additional high-level
utility methods to simplify creation and editing of tagged PDF
