【OpenLayers】绘制基本图形标注

let layer = new VectorLayer(); //新建一个绘线层
    let pointFeature = new Feature(new Point(fromLonLat([114.02, 24])));
    pointFeature.setStyle(
      new Style({
        //规则形状
        image: new RegularShape({
          fill: new Fill({ color: "#00FF00" }),
          stroke: new Stroke({ color: "blue", width: 2 }),
          points: 5, //角数量
          radius1: 20, //第一类角的半径
          radius2: 10, //第二类角的半径
        }),
      })
    );
    layer.setSource(
      new VectorSource({
        features: [pointFeature],
      })
    );
    map.addLayer(layer); //把线的图层添加到地图中
