Polygon.addPoint介绍

[英]Appends the specified coordinates to this Polygon.

If an operation that calculates the bounding box of this Polygon has already been performed, such as getBounds or contains, then this method updates the bounding box.
[中]将指定的坐标追加到此Polygon。
如果已经执行了计算此Polygon的边界框的操作，例如getBounds或contains，则此方法会更新边界框。
