百度地图（16）-矢量图标

1. 百度地图的矢量图标，其实还是使用 BMap.Marker 进行处理的， 只不过

这个Marker的icon 是以矢量的方式进行绘制。使用了BMap.Symbol 函数。

2. 代码

function addVectorSymbol() {
  var point = new BMap.Point(116.473008,39.916605);
  map.centerAndZoom(point, 16);
  map.enableScrollWheelZoom(true);

//设置marker图标为人字形
  vectorPeoplePath = new BMap.Marker(point, {
    // 设置自定义path路径25325l99
    icon: new BMap.Symbol('m0.5,48.67105l106.55963,0m-53.03642,45.73853l52.06349,51.09042m-52.06349,-51.57716l-48.65731,51.57716m48.41391,-112.39955l0,60.82238m16.17517,-77.24814c0,8.93415 -7.24208,16.17461 -16.17517,16.17461c-8.93307,0 -16.17464,-7.24046 -16.17464,-16.17461c0,-8.93309 7.24156,-16.1747 16.17464,-16.1747c8.93309,0 16.17517,7.24161 16.17517,16.1747z', {
