GC.fillPolygon介绍

[英]Fills the interior of the closed polygon which is defined by the specified array of integer coordinates, using the receiver's background color. The array contains alternating x and y values which are considered to represent points which are the vertices of the polygon. Lines are drawn between each consecutive pair, and between the first pair and last pair in the array.
[中]使用接收器的背景色填充由指定整数坐标数组定义的闭合多边形的内部。该数组包含交替的x和y值，这些值被视为表示作为多边形顶点的点。在每个连续对之间以及阵列中第一对和最后一对之间绘制线。
