itextsharp set bookmarks to fit page - itext

Question

I'm starting out with itextsharp and I've managed to answer all my questions but one:
How are bookmarks set to open to the fitpage zoom/view?
I apologize if this has already been answered elsewhere.
Here's my code if it helps.
//edit: Below is my working code. It has been modified using Bruno's example.
Public Sub MergePDFFiles(FileList As System.Collections.Generic.List(Of ModifiedItemForList), pdfName As String, pageCount As Integer)
Dim reader As PdfReader
Dim mergedPdf As Byte() = Nothing
Dim n As Integer
Dim page As Integer
Dim par As Paragraph
Dim pageMode As Integer
Dim pageLayout As Integer
Dim pageZoom As PdfDestination
Dim outlineZoom As PdfDestination
Dim pdfAction As PdfAction
Dim root As PdfOutline
Dim pdfOutline As PdfOutline
Using ms As New MemoryStream()
Using document As New Document()
Using copy As New PdfCopy(document, ms)
'Dim copy As New PdfCopy(document, ms)
document.Open()
root = copy.RootOutline
pageMode = copy.PageModeUseOutlines
pageLayout = copy.PageLayoutSinglePage
pageZoom = New PdfDestination(PdfDestination.FIT)
copy.ViewerPreferences = pageMode
pdfAction = pdfAction.GotoLocalPage(1, pageZoom, copy)
copy.SetOpenAction(pdfAction)
' For Each FilePath As KeyValuePair(Of String, String) In FileList ' .Count - 1
For i As Integer = 0 To pageCount - 1
' FilePath As KeyValuePair(Of String, String)
If File.Exists(FileList.Item(i).Value) Then
reader = New PdfReader(FileList.Item(i).Value)
' loop over the pages in that document
n = reader.NumberOfPages
page = 0
par = New Paragraph(FileList.Item(i).Key)
Debug.Print("FileList.Item(i).Key = " & FileList.Item(i).Key)
outlineZoom = New PdfDestination(PdfDestination.FIT)
pdfOutline = New PdfOutline(root, outlineZoom, par)
While page < n
copy.AddPage(copy.GetImportedPage(reader, System.Threading.Interlocked.Increment(page)))
End While
End If
Next
End Using
End Using
mergedPdf = ms.ToArray()
End Using
File.WriteAllBytes(pdfName, mergedPdf)
End Sub
Your input will be greatly appreciated,

If you want custom bookmarks, please don't use Chapter and Section, use PdfOutline instead. This is (of course) documented in chapter 7 of my book. If you need the C# port of the examples, take a look at the code examples for chapter 7, specifically CreateOutlineTree.cs, where instead of using PdfDestination.FITH (for Fit Horizontally) and a Y position, you just create a destination with PdfDestination.FIT (and no extra parameter):
new PdfOutline(root, new PdfDestination(PdfDestination.FIT), title, true);
