I was able to get the rotation with the following code:
Dim widgetDict As PdfDictionary = Nothing
Dim mkDict As PdfDictionary = Nothing
Dim rNum As PdfNumber = Nothing
widgetDict = afi.widgets(0)
If Not widgetDict Is Nothing Then
mkDict = widgetDict.GetAsDict(PdfName.MK)
If Not mkDict Is Nothing Then
rNum = mkDict.GetAsNumber(PdfName.R)
If Not rNum Is Nothing Then
return = rNum.DoubleValue
End If
End If
End If
But I am not checking that bit you referred to. Do you anticipate any
problems with the way it is here?
