I have a code in asp.net in C # in which one several PDF documents, each PDF has bookmarks and when I unite the files I do not respect the bookmarks.
With the ItextSharp library I manipulate the PDFs to join them, but as I mentioned before, I do not respect the bookmarks of each file.
Try adding bookmarks by joining the PDF as follows:
Chapter chapter4 = new ChapterAutoNumber("Prueba___1");
chapter4.BookmarkTitle = "Bubble Drawing";
sourceDocument.Add(chapter4);
Add the markers, but I need to respect the ones that previously had the documents before joining them.
