使用Win2d C＃获取有关行的信息

[英]Get info about a line using Win2d C#

原文 2016-07-15 22:28:34 5 1 c#/ uwp/ draw/ win2d

I'm drawing a line with win2d and C# uwp. 我正在用win2d和C＃uwp画一条线。 I would like to get infomation about that line such as the line length and even a list of points that are used to create that line. 我想获取有关该线的信息，例如线长，甚至是用于创建该线的点的列表。 I've tried everything I know and I just can't figure out a solution. 我已经尝试了所有我知道的东西，但我根本想不出解决方案。 Maybe I'm approaching this from the wrong angle? 也许我是从错误的角度来解决这个问题？ Can anyone help? 有人可以帮忙吗？

If you have information about the start and end, can't you apply this? 如果您有关于开始和结束的信息，您是否可以应用？ Length = (y1 - y2)^2 + (x1 - x2)^2 长度=（y1-y2）^ 2 +（x1-x2）^ 2
