如何检测SurfaceInkCanvas控件中的圆形手势？ [英] How to detect circle gesture in SurfaceInkCanvas control?

问题描述

众所周知，在WPF中，InkCanvas可以检测到圆形手势，并且它具有Gesture事件。但我发现SurfaceInkCanvas没有手势事件，所以我想知道如何检测SurfaceInkCanvas控件中的圆形手势？ SurfaceInkCanvas控件
可以处理系统手势，但是系统手势不包括圆圈手势。

As we know, in WPF, InkCanvas can detect the circle gesture, and it has the Gesture event. but I find the SurfaceInkCanvas hasn't the gesture event, so I want to know how to detect circle gesture in SurfaceInkCanvas control? The SurfaceInkCanvas control can deal the system gesture, but the system gesture doesn't include the circle gesture.

现在我需要实现两个人在一个圆圈绘制圆圈的功能同时认识他们。如果我可以使用SurfaceInkCanvas实现该功能？如果不能，如何实施呢？谢谢。

Now I need implement the feature that two peoples draw the circle at a same time and recognize them. If I can implement the feature using SurfaceInkCanvas? If can't, how to implement it? thanks.
