如何在Google地图自定义图标中添加圆形形状？

Question

我在地图上的自定义图像有问题。

例如： 我的图标，以这种方式产生，并且图标包含图像：

var ic = { //icon 
     url: icon, // url 
     scaledSize: new google.maps.Size(30, 30), // scaled size 
     origin: new google.maps.Point(0,0), // origin 
     anchor: new google.maps.Point(0, 0), // anchor 
     //define the shape 
     //define the shape 
     shape:{coords:[17,17,18],type:'circle'}, 
     //set optimized to false otherwise the marker will be rendered via canvas 
     //and is not accessible via CSS 
     optimized:false, 
     title: 'spot' 

    }; 

    var marker = new google.maps.Marker({ 
     map: map, title: name , position: latlngset, icon: ic 
    }); 

我想使我的图标，如CSS 50％半径（圆形）。 我该怎么做？

相关问题：JS Maps v3: custom marker with user profile picture

从那里使用代码，并改变边界半径至50％，给了我在圈内的图像的圆形图标。

    this.imageSrc = imageSrc; 
 
    // Once the LatLng and text are set, add the overlay to the map. This will 
 
    // trigger a call to panes_changed which should in turn call draw.

Answer 2

如果你想制作一个圆形标记只需检查documentation这是更快，更轻量。

否则，只需使您的实际图标变成圆形。
