示例

以下示例演示如何创建 DynamicRenderer 并将 添加到 RootVisualInkPresenter。 若要创建动态呈现墨迹的控件，请参阅 创建墨迹输入控件。

// Create a DrawingAttributes to use for the 
// DynamicRenderer.
DrawingAttributes inkDA = new DrawingAttributes();
inkDA.Width = 5;
inkDA.Height = 5;
inkDA.Color = Colors.Purple;

// Add a dynamic renderer plugin that 
// draws ink as it "flows" from the stylus
DynamicRenderer dynamicRenderer1 = new DynamicRenderer();
dynamicRenderer1.DrawingAttributes = inkDA;

this.StylusPlugIns.Add(dynamicRenderer1);
inkPresenter1.AttachVisuals(dynamicRenderer1.RootVisual,
    dynamicRenderer1.DrawingAttributes);

' Create a DrawingAttributes to use for the 
' DynamicRenderer.
Dim inkDA As New DrawingAttributes()
inkDA.Width = 5
inkDA.Height = 5
inkDA.Color = Colors.Purple

' Add a dynamic renderer plugin that 
' draws ink as it "flows" from the stylus
Dim dynamicRenderer1 As New DynamicRenderer()
dynamicRenderer1.DrawingAttributes = inkDA

Me.StylusPlugIns.Add(dynamicRenderer1)
inkPresenter1.AttachVisuals(dynamicRenderer1.RootVisual, dynamicRenderer1.DrawingAttributes)

注解

使用 时， DynamicRenderer必须使用 方法将 RootVisual 属性附加到 InkPresenterAttachVisuals 。
