FlowDocumentScrollViewer.Zoom プロパティ


現在のズーム レベルを取得または設定します。Gets or sets the current zoom level.

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



現在のズーム レベルはパーセンテージとして解釈されますThe current zoom level, interpreted as a percentage. 既定値は 100.0 (ズーム レベルは 100%) です。The default is 100.0 (a zoom level of 100%).

次の例は、Zoom 属性を設定する方法を示しています。The following example shows how to set the Zoom attribute.

  MinZoom="50" MaxZoom="1000"
  Zoom="120" ZoomIncrement="5"
      Flow content...

次の例は、Zoom プロパティをプログラムで設定する方法を示しています。The following example shows how to set the Zoom property programmatically.

FlowDocumentScrollViewer flowDocScrollViewer = new FlowDocumentScrollViewer();

// Enable content selection.
flowDocScrollViewer.IsSelectionEnabled = true;
// Enable the toolbar.
flowDocScrollViewer.IsToolBarVisible = true;

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

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("Flow content...")));
flowDocScrollViewer.Document = flowDoc;
Dim flowDocScrollViewer As New FlowDocumentScrollViewer()

With flowDocScrollViewer
    ' Enable content selection.
    .IsSelectionEnabled = True
    ' 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...")))
    .Document = flowDoc
End With


ズームレベルは、MinZoom プロパティと MaxZoom プロパティの値によって制限されます。The zoom level is constrained by the values of the MinZoom and MaxZoom properties.
