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

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

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

Paramètres

context

DrawingContext

Le DrawingContext de l’objet sur lequel le trait sera affiché.

Exemples

L’exemple suivant montre comment dessiner un Stroke objet à l’aide d’un 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)

Restitue l'objet Stroke basé sur les DrawingContext et DrawingAttributes spécifiés.

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)

Paramètres

drawingContext

DrawingContext

Le DrawingContext de l’objet sur lequel le trait sera affiché.

drawingAttributes

DrawingAttributes

Objet DrawingAttributes qui définit les attributs du trait qui est dessiné.

Exemples

L’exemple suivant montre comment dessiner un Stroke objet à l’aide d’un DrawingContext et DrawingAttributes.

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

    myStroke.Draw(myContext, myDAs);

    // Close the context
    myContext.Close();
