您好
1.文本
      var point = new SuperMap.Geometry.Point(0, 0);
        pointFeature = new SuperMap.Feature.Vector(point);
        pointFeature.style = {
                strokeColor: "#CAFF70",
                fillColor: "#DC143C",
                strokeWidth: 2,
                fillOpacity: 0.8,
                fontWeight: "bold",
                label: "东方\n Eastern",
                fontColor: "#FFF0F5"
            };
        vectorlayer.addFeatures(pointFeature);
2.制作标签专题图的形式
可参考https://iclient.supermap.io/examples/classic/editor.html#theme_themeLabelLayer
   //新建一个策略
    strategy = new SuperMap.Strategy.GeoText();
    //新建一个标签专题图层
    vectorLayer = new SuperMap.Layer.Vector("Label", {strategies: [strategy]});
    //设置标签的样式
    strategy.style = {
        fontColor: "#FF7F00",
        fontWeight: "bolder",
        fontSize: "14px",
        fill: true,
        fillColor: "#FFFFFF",
        fillOpacity: 1,
        stroke: true,
        strokeColor: "#8B7B8B"
    };
