WPF实现一个简单动画

<PointAnimation Storyboard.TargetName="line1" Storyboard.TargetProperty="Point" From="10,100" To="100,200" Duration="0:0:2" BeginTime="0:0:1"/>
<PointAnimation Storyboard.TargetName="line2" Storyboard.TargetProperty="Point" From="100,200" To="200,10" Duration="0:0:2" BeginTime="0:0:3"/>

</window>
用一个image显示一个简单的“打钩”效果的动画，但整个image会随着动画的过程而改变自身的大小，我想实现的是image大小固定，然后动画中的点是相对于image的位置，而不是相对于window。
当然，如果有更好的实现“打钩”动画的方法也可以介绍给我，本人新手，说的时候详细点，谢谢。

问题已解决，通过先画一个透明的相同图形，即可达到固定画面的作用。
