How to: Rotate an Object by Using a Geometric Path
This example shows how to rotate (pivot) an object along a geometric path that is defined by a xref:System.Windows.Media.PathGeometry object.
Example
The following example uses three xref:System.Windows.Media.Animation.DoubleAnimationUsingPath objects to move a rectangle along a geometric path.
-
The first xref:System.Windows.Media.Animation.DoubleAnimationUsingPath animates a xref:System.Windows.Media.RotateTransform that is applied to the rectangle. The animation generates angle values. It makes the rectangle rotate (pivot) along the contours of the path.
-
The other two objects animate the xref:System.Windows.Media.TranslateTransform.X%2A and xref:System.Windows.Media.TranslateTransform.Y%2A values of a xref:System.Windows.Media.TranslateTransform that is applied to the rectangle. They make the rectangle move horizontally and vertically along the path.

Another way to rotate an object by using a geometric path is to use a xref:System.Windows.Media.Animation.MatrixAnimationUsingPath object and set its xref:System.Windows.Media.Animation.MatrixAnimationUsingPath.DoesRotateWithTangent%2A property to true. For more information and an example, see Rotate an Object by Using a Geometric Path (Matrix Animation).
