Not all document types contain support for document structure. For these types of documents (such as TIF file or Text document), the value of IsStructureSupported of Document will be false and the Structure is null and should not be used. The rest of the discussion of this section is related to when IsStructureSupported is true.
Loading the document structure can take some time, therefore, it is not read automatically when a new Document is created from a disk or URL document. This is done so that the document is loaded as quick as possible and to not make the user wait if the bookmarks or table of content is not needed in your application.
To parse the document for bookmarks and table of content, use the Parse method while the value of ParseBookmarks is true (the default value). Usually you can call this method once after the Document is loaded. The IsParsed property can be used to check if the structure has been parsed.
If Parse is not called or the value of ParseBookmarks is false, then Bookmarks is an empty list. You can use it to add bookmarks if this is a brand new document that was obtained through DocumentFactory.Create in preparation to save.
When Parse is called and ParseBookmarks is true (the default value), the Bookmarks list will be updated with all the bookmarks and table of content items found in the original document. You can then read and modify these bookmarks if needed. If the value of ParseBookmarks is set to false, then Parse will not try to parse the bookmarks in the document.
Parse will also parse the document for any links found in the pages if the value of ParsePageLinks is true (the default value), these links can be obtain through the DocumentPage.GetLinks method. If the value of ParsePageLinks is set to false, then Parse will not try to parse the links found in the pages.
For an example, refer to Document.
