範例

以下程式碼範例示範如何在可擴充應用標記語言（XAML）中使用導出 MatrixAnimationUsingKeyFrames 類別。

                <!-- Animates the button's MatrixTransform using MatrixAnimationUsingKeyFrames. 
                Animates to first Matrix in the first 0.2 seconds, to second Matrix in the next
                second, and then starts over. Notice that the first KeyFrame stretches the button
                and skews it using the M11 and M12 Matrix properties respectively. Also, animations are 
                using Discrete interpolation, so the MatrixTransform appears to "jump" from one value 
                to the next. -->
