Property Value
The fill of the outline produced by this Pen. The default value is a null reference (Nothing in Visual Basic).This example shows how use a Pen to outline a shape. To create a simple Pen, you need only specify its Thickness and Brush. You can create more complex pen's by specifying a DashStyle, DashCap, LineJoin, StartLineCap, and EndLineCap.
The following example uses a Pen to outline a shape defined by a GeometryDrawing.
using System; using System.Windows; using System.Windows.Controls; using System.Windows.Media; namespace SDKSample { public partial class PenExample : Page { public PenExample() { // Create several geometries. RectangleGeometry myRectangleGeometry = new RectangleGeometry(); myRectangleGeometry.Rect = new Rect(0, 0, 50, 50); EllipseGeometry myEllipseGeometry = new EllipseGeometry(); myEllipseGeometry.Center = new Point(75, 75); myEllipseGeometry.RadiusX = 50; myEllipseGeometry.RadiusY = 50; LineGeometry myLineGeometry = new LineGeometry(); myLineGeometry.StartPoint = new Point(75, 75); myLineGeometry.EndPoint = new Point(75, 0); // Create a GeometryGroup and add the geometries to it. GeometryGroup myGeometryGroup = new GeometryGroup(); myGeometryGroup.Children.Add(myRectangleGeometry); myGeometryGroup.Children.Add(myEllipseGeometry); myGeometryGroup.Children.Add(myLineGeometry); // Create a GeometryDrawing and use the GeometryGroup to specify // its geometry. GeometryDrawing myGeometryDrawing = new GeometryDrawing(); myGeometryDrawing.Geometry = myGeometryGroup; // Add the GeometryDrawing to a DrawingGroup. DrawingGroup myDrawingGroup = new DrawingGroup(); myDrawingGroup.Children.Add(myGeometryDrawing); // Create a Pen to add to the GeometryDrawing created above. Pen myPen = new Pen(); myPen.Thickness = 10; myPen.LineJoin = PenLineJoin.Round; myPen.EndLineCap = PenLineCap.Round; // Create a gradient to use as a value for the Pen's Brush property. GradientStop firstStop = new GradientStop(); firstStop.Offset = 0.0; Color c1 = new Color(); c1.A = 255; c1.R = 204; c1.G = 204; c1.B = 255; firstStop.Color = c1; GradientStop secondStop = new GradientStop(); secondStop.Offset = 1.0; secondStop.Color = Colors.Purple; LinearGradientBrush myLinearGradientBrush = new LinearGradientBrush(); myLinearGradientBrush.GradientStops.Add(firstStop); myLinearGradientBrush.GradientStops.Add(secondStop); myPen.Brush = myLinearGradientBrush; myGeometryDrawing.Pen = myPen; // Create an Image and set its DrawingImage to the Geometry created above. Image myImage = new Image(); myImage.Stretch = Stretch.None; myImage.Margin = new Thickness(10); DrawingImage myDrawingImage = new DrawingImage(); myDrawingImage.Drawing = myDrawingGroup; myImage.Source = myDrawingImage; this.Content = myImage; } } }
