Bookmarks can be added to or removed from a PDF document using the Bookmark methods. PDF bookmarks are constructed as a linked list, with one root node. The following is an example of a bookmark list structure:
In the above example, Chapter One is a child of Root, Chapter Two is a sibling of Chapter One, and Part I is a child of Chapter One.
Add Bookmarks
Each bookmark node in the list is represented by a BookmarkContext object.
The root BookmarkContext of the PDF document's bookmark list can be retrieved by calling GetBookmarkRoot.
A child bookmark can be added to any node in the bookmark list, by calling AddBookmarkChild. After one child has been specified, additional siblings are added by calling AddBookmarkSibling.

// This code demonstrates adding a child bookmark to a node in the bookmark list Accusoft.PdfXpressSdk.PdfXpress pdfXpress1 = null; Accusoft.PdfXpressSdk.Document document = null; BookmarkContext parent = null; try { pdfXpress1 = new PdfXpress(); pdfXpress1.Initialize(); document = new Document (pdfXpress1, "C:\\test.pdf"); parent = document.GetBookmarkRoot(); parent = document.GetBookmarkChild(parent); BookmarkContext child = document.CreateBookmark(); child.Title = "bookmark1"; child.ActionPageNumber = 0; parent = document.GetBookmarkRoot(); } catch (System.Exception ex) { } finally { if ( null != parent)parent.Dispose(); if ( null != document ) document.Dispose( ); if ( null != pdfXpress1 ) pdfXpress1.Dispose( ); } |

Remove Bookmarks
To remove a bookmark from a PDF document, call the RemoveBookmark method.
| C# Example | Copy Code |
|---|---|
// This code demonstrates deleting a bookmark from a PDF file Accusoft.PdfXpressSdk.PdfXpress pdfXpress1 = null; Accusoft.PdfXpressSdk.Document document = null; BookmarkContext parent = null; try { pdfXpress1 = new PdfXpress(); pdfXpress1.Initialize(); document = new Document(pdfXpress1, "C:\\test.pdf"); parent = document.GetBookmarkRoot(); parent = document.GetBookmarkChild(parent); parent = document.GetBookmarkChild(parent); document.RemoveBookmark(parent); } catch (System.Exception ex) { } finally { if ( null != parent)parent.Dispose(); if ( null != document ) document.Dispose( ); if ( null != pdfXpress1 ) pdfXpress1.Dispose( ); } |
