Definition

Namespace:

System.Windows.Ink

Assembly:

PresentationCore.dll

Rendert das Stroke-Objekt auf Grundlage eines DrawingContext.

Überlädt

Draw(DrawingContext)	Rendert das Stroke-Objekt basierend auf dem angegebenen DrawingContext.
Draw(DrawingContext, DrawingAttributes)	Rendert das Stroke-Objekt auf Grundlage des angegebenen DrawingContext und der DrawingAttributes.

Draw(DrawingContext)

Rendert das Stroke-Objekt basierend auf dem angegebenen DrawingContext.

public:
 void Draw(System::Windows::Media::DrawingContext ^ context);

public void Draw (System.Windows.Media.DrawingContext context);

member this.Draw : System.Windows.Media.DrawingContext -> unit

Public Sub Draw (context As DrawingContext)

Parameter

context

DrawingContext

Das DrawingContext-Objekt, in dem der Strich gerendert wird.

Beispiele

Im folgenden Beispiel wird veranschaulicht, wie Sie ein Stroke Objekt mithilfe einer DrawingContext.

protected DrawingVisual DrawDCOnly(Stroke myStroke)
{
    // Create new Visual context to draw on
    DrawingVisual myVisual = new DrawingVisual();
    DrawingContext myContext = myVisual.RenderOpen();

    // myMatrix is scaled by:
    // myMatrix.Scale(0.5, 0.5)
    myStroke.Transform(myMatrix, false);

    // Draw the stroke on the Visual context using DrawingContext
    myStroke.Draw(myContext);

    // Close the context
    myContext.Close();

    return myVisual;
}

Function DrawDCOnly(ByVal myStroke As Stroke) As DrawingVisual

    ' Create new Visual context to draw on
    Dim myVisual As DrawingVisual = New DrawingVisual()
    Dim myContext As DrawingContext = myVisual.RenderOpen()

    ' myMatrix is scaled by:
    ' myMatrix.Scale(0.5, 0.5)
    myStroke.Transform(myMatrix, False)

    ' Draw the stroke on the Visual context using DrawingContext
    myStroke.Draw(myContext)

    ' Close the context
    myContext.Close()

    Return myVisual

End Function

Draw(DrawingContext, DrawingAttributes)

Rendert das Stroke-Objekt auf Grundlage des angegebenen DrawingContext und der DrawingAttributes.

public:
 void Draw(System::Windows::Media::DrawingContext ^ drawingContext, System::Windows::Ink::DrawingAttributes ^ drawingAttributes);

public void Draw (System.Windows.Media.DrawingContext drawingContext, System.Windows.Ink.DrawingAttributes drawingAttributes);

member this.Draw : System.Windows.Media.DrawingContext * System.Windows.Ink.DrawingAttributes -> unit

Public Sub Draw (drawingContext As DrawingContext, drawingAttributes As DrawingAttributes)

Parameter

drawingContext

DrawingContext

Das DrawingContext-Objekt, in dem der Strich gerendert wird.

drawingAttributes

DrawingAttributes

Das DrawingAttributes-Objekt, das die Attribute des Strichs definiert, der gezeichnet wird.

Beispiele

Im folgenden Beispiel wird veranschaulicht, wie Sie ein Objekt mithilfe einer Stroke und einer DrawingContext .DrawingAttributes

protected DrawingVisual DrawDCandDA(Stroke myStroke)
{
    // Create new Visual context to draw on
    DrawingVisual myVisual = new DrawingVisual();
    DrawingContext myContext = myVisual.RenderOpen();

    // Draw stroke using DrawingContext and DrawingAttributes
    // (to make the stroke magenta)
    DrawingAttributes myDAs = new DrawingAttributes();
    myDAs.Color = Colors.Magenta;

    myStroke.Draw(myContext, myDAs);

    // Close the context
    myContext.Close();

    return myVisual;
}

Function DrawDCandDA(ByVal myStroke As Stroke) As DrawingVisual

    ' Create new Visual context to draw on
    Dim myVisual As DrawingVisual = New DrawingVisual()
    Dim myContext As DrawingContext = myVisual.RenderOpen()

    ' Draw stroke using DrawingContext and DrawingAttributes
    ' (to make the stroke magenta)
    Dim myDAs As DrawingAttributes = New DrawingAttributes()
    myDAs.Color = Colors.Magenta

    myStroke.Draw(myContext, myDAs)

    ' Close the context
    myContext.Close()

    Return myVisual

End Function
