Does your pdf sdk have features for accessible tagging, section 508 compliance?
A:
PDFNet SDK can be used to create and process tagged, accessible, and section 508 compliant PDFs.
Since the topic of tagging and accessibility is very broad, could you please elaborate a bit on your requirements?
Are you looking to create new files, or tag existing content, extract content, … ?
To get you started, you may want to take a look at following PDFNet samples:
LogicalStructure: https://www.pdftron.com/pdfnet/samplecode.html#LogicalStructure
TextExtract: https://www.pdftron.com/pdfnet/samplecode.html#TextExtract
as well as PDFGenie tool (also available as an add-on API to PDFNet):
https://www.pdftron.com/pdfgenie
which lets you extract some structural info (like reading order, tables, columns, paragraphs, etc) from existing PDF documents.
