示例

以下示例演示如何设置 StylusTipTransform 属性。 该示例假定应用程序具有一个已调用inkCanvas1对象和两DrawingAttributes个InkCanvas调用inkDA的对象highlighterDA。 有关完整示例，请参阅 DrawingAttributes 类概述。

// Set up the DrawingAttributes for the pen.
inkDA = new DrawingAttributes();
inkDA.Color = Colors.SpringGreen;
inkDA.Height = 5;
inkDA.Width = 5;
inkDA.FitToCurve = false;
inkDA.StylusTipTransform = new Matrix(1, 0, 0, 5, 0, 0);

// Set up the DrawingAttributes for the highlighter.
highlighterDA = new DrawingAttributes();
highlighterDA.Color = Colors.Orchid;
highlighterDA.IsHighlighter = true;
highlighterDA.IgnorePressure = true;
highlighterDA.StylusTip = StylusTip.Rectangle;
highlighterDA.Height = 30;
highlighterDA.Width = 10;

inkCanvas1.DefaultDrawingAttributes = inkDA;

' Set up the DrawingAttributes for the pen.
inkDA = New Ink.DrawingAttributes()
With inkDA
    .Color = Colors.SpringGreen
    .Height = 5
    .Width = 5
    .FitToCurve = True
    .StylusTipTransform = New Matrix(1, 0, 0, 1, 20, 0)
End With

' Set up the DrawingAttributes for the highlighter.
highlighterDA = New Ink.DrawingAttributes()
With highlighterDA
    .Color = Colors.Orchid
    .IsHighlighter = True
    .IgnorePressure = True
    .StylusTip = StylusTip.Rectangle
    .Height = 30
    .Width = 10
End With

inkCanvas1.DefaultDrawingAttributes = inkDA

注解

StylusTipTransform使用属性旋转、倾斜或缩放触笔提示。
