是否可以在Google静态地图上绘制圆圈？ [英] Is it possible to draw a circle on a Google static map?

问题描述

静态地图API讨论路径，但没有提及圆圈。这可能吗？
谢谢

The static map API discusses paths, but no mention of circles. Is this possible? Thanks

推荐答案

您可以使用编码折线算法来产生足够的点以获得大致圆形的路径。确实存在编码问题：您需要获取圆圈的中心和半径，将其转化为一系列经纬度，然后使用算法进行编码。

What you could do is use the encoded polyline algorithm to produce enough points to get a roughly circular path. There's definitely coding involved: you'd need to get the center and radius of your circle, turn that into a series of lat/longs, then encode using the algorithm.

或者，您可以使用透明的gif图片作为标记并将其放入地图中。

As an alternative, you might be able to use a transparent gif image as a marker and put that in your map.
