範例

下列範例示範如何使用兩 DrawingAttributes 個 物件，在相同的 InkCanvas 上使用畫筆和醒目提示器來模擬。 醒目提示的 StylusTip 屬性會設定為 Rectangle。

此範例假設 「XAML」 檔案中的根項目稱為 DockPanelroot 。 它也會假設有呼叫 ButtonbtnToggleHighlighter 的 ，而且 Click 事件已連線到事件處理常式。

InkCanvas inkCanvas1 = new InkCanvas();
DrawingAttributes inkDA;
DrawingAttributes highlighterDA;
bool useHighlighter = false;

// Add an InkCanvas to the window, and allow the user to 
// switch between using a green pen and a purple highlighter 
// on the InkCanvas.
private void WindowLoaded(object sender, EventArgs e)
{
    inkCanvas1.Background = Brushes.DarkSlateBlue;
    inkCanvas1.DefaultDrawingAttributes.Color = Colors.SpringGreen;

    root.Children.Add(inkCanvas1);

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

    // 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;
}

// Create a button called switchHighlighter and use 
// SwitchHighlighter_Click to handle the Click event.  
// The useHighlighter variable is a boolean that indicates
// whether the InkCanvas renders ink as a highlighter.

// Switch between using the 'pen' DrawingAttributes and the 
// 'highlighter' DrawingAttributes.
void SwitchHighlighter_Click(Object sender, RoutedEventArgs e)

    useHighlighter = !useHighlighter;

        inkCanvas1.DefaultDrawingAttributes = highlighterDA;
    }
    else
    {
        switchHighlighter.Content = "Use Highlighter";
        inkCanvas1.DefaultDrawingAttributes = inkDA;
    }
}

Private WithEvents inkCanvas1 As New InkCanvas()
Private inkDA As DrawingAttributes
Private highlighterDA As DrawingAttributes
Private useHighlighter As Boolean = False

    root.Children.Add(inkCanvas1)

    ' Set up the DrawingAttributes for the pen.
    inkDA = New DrawingAttributes()
    With inkDA
        .Color = Colors.SpringGreen
        .Height = 5
        .Width = 5
        .FitToCurve = True
    End With

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

End Sub

您可以藉由設定 DrawingAttributes.StylusTip 屬性來指定用來繪製 Stroke 物件的小費圖形。
