问题描述
是否有任何已知的方法来计算两个矩形的交集矩形？我的意思是，如果矩形A被（X1，Y2，X2，Y2）和B由（X3，Y3，X4，Y4），我该如何计算交会矩形C的坐标定义（X5，Y5，5233，Y6 ）？
Is there any known approach to compute the intersection rectangle between two rectangles? I mean if the rectangle A is defined by (x1,y2, x2,y2) and B by (x3,y3, x4,y4), how do I compute the coordinates of the intersection rectangle C (x5,y5, x6,y6)?
感谢。

相交多边形的普遍问题进行了详细说明如下：的。顺便说一句，对于任务的最佳库，与绑定几种编程语言之一，是GPC - 通用多边形快船库：的
The general problem of intersecting polygons is explained in detail in here: http://davis.wpi.edu/~matt/courses/clipping . Incidentally, one of the best libraries for the task, with bindings for several programming languages, is GPC - the General Polygon Clipper library: http://www.cs.man.ac.uk/~toby/alan/software
