百度地图路线规划重新设置起点、终点图标和路线颜色

重新设置起点、终点图标：

var driving = new BMap.DrivingRoute(_this.mapModel, {
      renderOptions: {
          map: _this.mapModel,
          autoViewport: true
     }
});

//重新设置起始点，终点图标和偏移
var startIcon = new BMap.Icon(require('../assets/support/ic_qidian.png'), new BMap.Size(30,120),{anchor: new BMap.Size(10, 25),});
var endIcon = new BMap.Icon(require('../assets/support/ic_zhongdian.png'), new BMap.Size(30,120),{anchor: new BMap.Size(10, 25),});

_this.driving.setMarkersSetCallback(function(result){
       result[0].marker.setOffset(new BMap.Size(0, 40));
      result[0].marker.setIcon(startIcon);
      result[1].marker.setOffset(new BMap.Size(12, 45));
      result[1].marker.setIcon(endIcon);
})
var driving = new B
