// Enable printing...
flowDocRdr.IsPrintEnabled = true;
// Set zoom between 50% and 1000%.
flowDocRdr.MinZoom = 50;
flowDocRdr.MaxZoom = 1000;
// Set the zoom increment to 5%.
flowDocRdr.ZoomIncrement = 5;
// Set the initial zoom to 120%.
flowDocRdr.Zoom = 120;

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("Flow content...")));
flowDocRdr.Document = flowDoc;

Dim flowDocRdr As New FlowDocumentReader()

' Enable find...
flowDocRdr.IsFindEnabled = True
' Enable printing...
flowDocRdr.IsPrintEnabled = True
' Set zoom between 50% and 1000%.
flowDocRdr.MinZoom = 50
flowDocRdr.MaxZoom = 1000
' Set the zoom increment to 5%.
flowDocRdr.ZoomIncrement = 5
' Set the initial zoom to 120%.
flowDocRdr.Zoom = 120

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

備註

預設 FlowDocumentReader 使用者介面 (UI) 包含可用來調整層級的 Zoom 滑杆。 此屬性會指定滑杆的 Zoom 下限值。
