如何在两个像素角之间找到 [英] How do I find between two pixcel angle

问题描述

嗨。我如何找到两个像素之间的角度...

Hi.How do I find angle between two pixcels...

推荐答案

尝试：

Try:

Point p1 = new Point(100, 100);
Point p2 = new Point(150, 50);
double radians = Math.Atan2(p2.Y - p1.Y, p2.X - p1.X);

Google是你的朋友;）

网上有很多资源。

例如： http：// cplus .about.com / od / learnc / a /计算 - 相对角度 - 两点之间.htm [ ^ ]

Google is your friend ;)
There is a lot of resources about that online.
For example : http://cplus.about.com/od/learnc/a/Calculating-The-Relative-Angle-Between-Two-Points.htm[^]

感觉：两个像素之间没有角度。

你需要至少3个像素，这可以定义两个段;然后你可以测量这些段之间的角度。



请澄清你的问题。

That makes no sense : there is no angle between two pixels.
You need at least 3 pixels, which could define two segments; you can then measure an angle between these segments.

Please clarify your question.
