Post subject: | PDFSharp Outline Help |
Hello! Thank you for such a wonderful tool! I am making a small program that appends a page to a large PDF file and creates a new bookmark for it using a name provided by the user. It will work with my test files - no outline and single level outline - but will throw an exception when I try using a multi-level outline as my destination: Code: //Open the files PdfDocument inputDestination = PdfReader.Open(pathDestination, PdfDocumentOpenMode.Import); PdfDocument inputSource = PdfReader.Open(pathSource, PdfDocumentOpenMode.Import); //Inserts the Source page in to the ScanDoc PdfPage newPage = inputSource.Pages[0]; inputDestination.AddPage(newPage); //Bookmarking string bookmarkName = Interaction.InputBox("Please provide a name for the bookmark:", "New Bookmark"); int count = inputDestination.PageCount -1; PdfPage lastPage = inputDestination.Pages[count]; PdfOutline outline = inputDestination.Outlines.Add(bookmarkName, lastPage); //Saves the ScanDoc inputDestination.Save(pathDestination); Throws an error against that last line of my "Bookmarking" block: Code: System.Reflection.TargetInvocationException: 'Exception has been thrown by the target of an invocation.' This exception was originally thrown at this call stack: PdfSharp.Pdf.PdfOutline.SplitDestinationPage(PdfSharp.Pdf.PdfArray) PdfSharp.Pdf.PdfOutline.Initialize() PdfSharp.Pdf.PdfOutline.InitializeChildren() PdfSharp.Pdf.PdfOutline.Initialize() PdfSharp.Pdf.PdfOutline.InitializeChildren() PdfSharp.Pdf.PdfOutline.Initialize() PdfSharp.Pdf.PdfOutline.InitializeChildren() PdfSharp.Pdf.PdfOutline.Initialize() PdfSharp.Pdf.PdfOutline.PdfOutline(PdfSharp.Pdf.PdfDictionary) I know I am missing something with the levels, but I cannot find anything in the documentation. I just need the bookmark created in the tree, it can be manually moved where needed. My thanks in advance for any advice or direction anyone can provide. |
