UIElement.Clip Property
Gets or sets the geometry used to define the outline of the contents of an element. This is a dependency property.
Assembly: PresentationCore (in PresentationCore.dll)
This example shows how to define a framework element'sClipregion. To define a clip, use a Geometry (for example, an EllipseGeometryto set the element's Clipproperty. Only the area that is within the region of the geometry will be visible.
The following example shows an Imageelement without a defined clip region. Because no clip region is defined, the entire image is displayed.
<Image Source="sampleImages\Waterlilies.jpg" Width="200" Height="150" HorizontalAlignment="Left" />

Image with No Clip Region
In the next example, an identical Image is created, except that it has a defined clip region. Only the part of the image that is within the area the EllipseGeometrywill be displayed.
<Image Source="sampleImages\Waterlilies.jpg" Width="200" Height="150" HorizontalAlignment="Left"> <Image.Clip> <EllipseGeometry RadiusX="100" RadiusY="75" Center="100,75"/> </Image.Clip> </Image>

Image with an Elliptical Clip Region
The following example shows how animate a framework element's Clip region. In this example, an EllipseGeometry is used to define an elliptical clip region for an Image element. A PointAnimation animates the ellipse geometry's Center property from (0, 0) to (200, 150). The animation starts playing after the image is loaded and repeats indefinitely.
<Image Source="sampleImages\Waterlilies.jpg" Width="200" Height="150" HorizontalAlignment="Left"> <Image.Clip> <EllipseGeometry x:Name="MyEllipseGeometry1" RadiusX="100" RadiusY="75" Center="100,75"/> </Image.Clip> <Image.Triggers> <EventTrigger RoutedEvent="Image.Loaded"> <BeginStoryboard> <Storyboard> <PointAnimation Storyboard.TargetName="MyEllipseGeometry1" Storyboard.TargetProperty="(EllipseGeometry.Center)" From="0,0" To="200,150" Duration="0:0:3" RepeatBehavior="Forever" AutoReverse="True" /> </Storyboard> </BeginStoryboard> </EventTrigger> </Image.Triggers> </Image>
