使用 Itextsharp 从 pdf 获取 acrofields 字体

Question

我需要从 pdf 表单的特定字段中获取字体信息、名称和大小。在 pdf 中有更多具有相同名称和不同字体的字段，我不想编辑 pdf 字段的名称。我正在使用 Itexsharp。谁能帮我这个？谢谢。

我解决了，它的工作原理是这样的：

Private Sub FieldsFontProperties(ByVal Path As String)
    Dim Reader As PdfReader = New PdfReader(Path)
    Dim Fields As AcroFields = Reader.AcroFields

    For Each Field In Fields.Fields
        Dim Item As AcroFields.Item = Fields.GetFieldItem(Field.Key)
        Dim TextField As TextField = New TextField(Nothing, Nothing, Nothing)
        Fields.DecodeGenericDictionary(Item.GetMerged(0), TextField)
        Dim t As String()() = TextField.Font.FullFontName

        Dim FontName As String = t(0)(3)
        Dim FontSize As Single = TextField.FontSize
    Next
End Sub
