How to set inherit zoom for bookmarks?

[Crix]

Hey,

How do I set the zoom factor for all bookmarks of a PDF-document to "inherit zoom" using Spire.PDF?
Thanks in advance.

Hello,

Thanks for your inquiry. Sorry that at present Spire.Pdf doesn't support the feature, and I have added it to our schedule, once it is added, we will let you know.

Hello,

By investigating further, you can set the zoom property of bookmark to 0, which is inherit zoom.

Code: Select all

PdfDocument pdfdoc = new PdfDocument();
pdfdoc.LoadFromFile(fileName);
foreach (var bookMark in pdfdoc.Bookmarks)
        {
            (bookMark as PdfBookmark).Destination.Zoom = 0;
        }

Hey Gary,

Thank you for your investigations. Unfortunately I did not get it to work. The bookmarks of my Test-PDF remain as "Fit Page". Also, when re-running the code on the same document I get a System.NullReferenceException (Bookmark.Destination = Nothing). Here is what i have got: (VB.NET)

Code: Select all

    Private Sub SetInheritZoom(FileName As String)
        Dim Document As New PdfDocument()
        Document.LoadFromFile(FileName)

        For Each Bookmark As Bookmarks.PdfBookmark In Document.Bookmarks
            Bookmark.Destination.Zoom = 0 'System.NullReferenceException
        Next Bookmark

        Document.SaveToFile(FileName)
        Document.Close()

        Process.Start(FileName)
    End Sub

What did I do wrong?
