WPF元素超出了usercontrol [英] WPF element gets out of usercontrol

问题描述

所以，我有下一个问题（见图片）

我有一个包含用户控件的窗口。在我的用户控件中，我有一个椭圆，显示在用户控件中，也在其外部（图1）。我只需要显示那个位于用户控件内的部分（图像2）

图片1 [ ^ ]

图片2 [ ^ ]

So, i have next problem (see images)
I have a window that contains a user control. in my user control i have an ellipse that is shown in user control and also outside of it (image 1). i need to show only that part, that is located inside of user control (image 2)
Image 1[^]
Image 2[^]

推荐答案

从你的问题来看，目前还不清楚你是如何使用椭圆在用户控件之外获取图像的。在所有情况下，如图2所示，呈现控件的一种方法是： http://msdn.microsoft.com/en-us/library/system.windows.uielement.cliptobounds%28v=vs.110%29.aspx [ ^ ]。

From your question, it's not clear how exactly you obtained the image with ellipse going outside of a user control. In all cases, one method to present the control as shown on Figure 2 is this: http://msdn.microsoft.com/en-us/library/system.windows.uielement.cliptobounds%28v=vs.110%29.aspx[^].
