Polygon介绍

[英]The Polygon class encapsulates a description of a closed, two-dimensional region within a coordinate space. This region is bounded by an arbitrary number of line segments, each of which is one side of the polygon. Internally, a polygon comprises of a list of (x, y) coordinate pairs, where each pair defines a vertex of the polygon, and two successive pairs are the endpoints of a line that is a side of the polygon. The first and final pairs of (x, y) points are joined by a line segment that closes the polygon. This Polygon is defined with an even-odd winding rule. (The even-odd rule specifies that a point lies inside the path if a ray drawn in any direction from that point to infinity is crossed by path segments an odd number of times.) This class's hit-testing methods, which include the contains, intersects and inside methods, use the insideness definition described in the Shape class comments.
[中]Polygon类封装了坐标空间中封闭二维区域的描述。该区域由任意数量的线段包围，每个线段都是多边形的一侧。在内部，多边形由一系列（x，y）坐标对组成，每对坐标对定义多边形的一个顶点，两个连续的坐标对是多边形边的一条直线的端点。第一对和最后一对（x，y）点由闭合多边形的线段连接。这个Polygon是用奇偶缠绕规则定义的*（奇偶规则规定，如果从该点到无穷远的任何方向绘制的光线与路径段相交奇数次，则该点位于路径内。）*该类的命中测试方法，包括contains、intersects和inside方法，使用Shape类注释中描述的内部性定义。
