property System::Windows::Rect ElementBounds { System::Windows::Rect get(); };

Public ReadOnly Property ElementBounds As Rect
Property Value
The cached bounds of the element.
Examples
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;
imageBrush.Freeze();
}
If imageBrush Is Nothing Then
' 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 = ElementBounds
imageBrush.Freeze()
End If
Remarks
The StylusPlugIn caches the bounds of its element to perform hit testing.
