                ' Enable the toolbar.
                .IsToolBarVisible = True

                ' Set zoom between 50% and 1000%.
                .MinZoom = 50
                .MaxZoom = 1000
                ' Set the zoom increment to 5%.
                .ZoomIncrement = 5
                ' Set the initial zoom to 120%.
                .Zoom = 120

                Dim flowDoc As New FlowDocument(New Paragraph(New Run("Flow content...")))
