问题描述
此五角大楼的例子显示了孔可多边形内部添加：的
This Pentagon example shows holes can be added inside a Polygon: http://code.google.com/p/gmaps-samples-v3/source/browse/trunk/poly/pentagon.html?r=40
我想补充一个圆圈里面一个洞。
I would like to add a hole inside a circle.
目前，我通过一个圆形的多边形，并把内部和外部边界在它模仿这一点，它工作正常，然而code极长看到的地图有〜15圈。
Currently I am mimicking this by making a circle shape polygon and putting inner and outer bounds and it is working fine, however the code is extremely long seeing as the map has ~15 circles in it.
任何帮助将是非常美联社preciated
Any help would be much appreciated
谢谢！
推荐答案
我没有找到Circle类东西，但有人想出了一个功能，这将减少你的code尺寸。它做你正在做同样的事情，创造形状像一个圆的多边形。
I didn't find anything for the Circle class, but someone has figured out a function that will reduce your code size. It does the same thing you are doing, creating polygons shaped like a circle.
函数画圆（点，半径，DIR）使用DIR来区分正空间和漏洞。你必须交替他们创造洞。
The function drawCircle(point, radius, dir) uses dir to distinguish positive space and holes. You have to alternate them to create holes.
