PdfStreamWriter supports the majority of the PDF format features and preserves them in the resultant document.
Since the current PdfStreamWriter API provides methods for merging separate pages, the page content and the related page properties will be preserved unmodified. However, PDF document properties will not be imported and will not be preserved in the generated PDF file. Such properties are:
- Document Outlines (Bookmarks)
- Interactive form fields
- Article threads
- Named destinations
- Document metadata
Also, destinations leading to other pages are not preserved with the current version, except from the cases when they lead to the same page or to a previously merged page.
