The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets the cached bounds of the element.

Namespace:   System.Windows.Input.StylusPlugIns
Assembly:  PresentationCore (in PresentationCore.dll)

public Rect ElementBounds { get; }

Property Value

Type: System.Windows.Rect

The cached bounds of the element.

The StylusPlugIn caches the bounds of its element to perform hit testing.

The following example demonstrates how a DynamicRenderer, which inherits from StylusPlugIn, uses an ImageBrush to render a stroke. This brush partially draws the image file specified by imageFile.

if (imageBrush == null)
    // Create an ImageBrush.  imageFile is a string that's a path to an image file.
    image1 = new BitmapImage(new Uri(imageFile));
    imageBrush = new ImageBrush(image1);

    // Don't tile, don't stretch; align to top/left.
    imageBrush.TileMode = TileMode.None;
    imageBrush.Stretch = Stretch.None;
    imageBrush.AlignmentX = AlignmentX.Left;
    imageBrush.AlignmentY = AlignmentY.Top;

    // Map the brush to the entire bounds of the element.
    imageBrush.ViewportUnits = BrushMappingMode.Absolute;
    imageBrush.Viewport = this.ElementBounds;
