Adding Bookmarks to PDF file

Bookmarks give you the option to keep track/link to specific page inside the PDF document. PdfContentEditor class in Aspose.Pdf.Facades namespace provides a feature which allows you to create your own bookmark in a sophisticated yet intuitive way within an existing PDF file, at a given page or all pages.

Implementation details

Other than the creation of simple bookmarks, sometimes you have a requirement to create a bookmark in the form of chapters where you nest the individual bookmarks inside of the chapter bookmarks so that when you click on the + sign for a chapter you would see the pages inside when the bookmarks expands, as shown in the picture below .

    string dataDir = RunExamples.GetDataDir_AsposePdf_WorkingDocuments();

    // Open document
    using (var document = new Aspose.Pdf.Document(dataDir + "Sample.pdf"))
    {
        var editor = new Aspose.Pdf.Facades.PdfContentEditor(document);

        editor.CreateBookmarksAction("Bookmark 1", System.Drawing.Color.Green, true, false, string.Empty, "GoTo", "2");

    }
}
