arcgis for js根据经纬度添加图片标注

1.声明三个包

• esri/layers/GraphicsLayer
• esri/Graphic

• esri/geometry/Point
  2.声明GraphicsLayer并且add到map里面
  3.初始化图片标记点并且add到GraphicsLayer

  async ShowLocation() {
      let that = this
      const Graphic = await arcgisPackage.Graphic
      const GraphicsLayer = await arcgisPackage.GraphicsLayer
      const Point = await arcgisPackage.Point
      
      let layer = new GraphicsLayer()
      that.map.add(layer)
  
      var symbol = {
        type: "picture-marker",
        url: require('../../../assets/img/onepicture/ta.png'),//图片地址
        width: "64px",
        height: "64px"
      };
      var point = new Point(103.880812,27.802255);
      var gp = new Graphic(point,symbol);
  
      layer.graphics.add(gp);
    },
