Accessibility and Compliance
The PDF Document API allows you to create accessible PDF documents and standards-compliant electronic invoices.
Accessible PDF documents contain a logical structure tree that describes document elements such as headings, paragraphs, and tables. Assistive technologies use this structure to interpret document content and improve accessibility.
The PDF Document API supports the following accessibility and compliance features:
- Generate, inspect, and update tagged PDF documents.
- Map custom structure tags to standard PDF roles.
- Modify or remove elements from an existing document structure tree.
- Create ZUGFeRD-compliant electronic invoices.
- Generate documents in PDF/UA-1 and PDF/UA-2 compliant formats.
