通过

FlowDocumentReader.MinZoom 属性

  • 参考

定义

命名空间:
System.Windows.Controls
程序集:
PresentationFramework.dll

获取或设置 Zoom 允许的最小 FlowDocumentReader 级别。

public:
 property double MinZoom { double get(); void set(double value); };
public double MinZoom { get; set; }
member this.MinZoom : double with get, set
Public Property MinZoom As Double

属性值

Double

Zoom 允许的最小 FlowDocumentReader 级别，以百分比表示。 默认值是 80.0（最小缩放比例为 80%）。

示例

以下示例演示如何设置 MinZoom 属性。

<FlowDocumentReader
  IsFindEnabled="True"  
  IsPrintEnabled="True"
  MinZoom="50" MaxZoom="1000"
  Zoom="120" ZoomIncrement="5"
>
  <FlowDocument>
    <Paragraph>
      Flow content...
    </Paragraph>
  </FlowDocument>
</FlowDocumentReader>

下面的示例演示如何以编程方式设置 MinZoom 属性。

FlowDocumentReader flowDocRdr = 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;

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

注解

FlowDocumentReader默认用户界面 (UI) 包含可用于调整Zoom级别的滑块。 此属性指定滑块的 Zoom 下限值。
