如上面的WMTS的配置文件，我只想显示9-18级，应该怎么写呢？zoomOffset不好使..

Answer 1

您好，您可以在实例化地图时设置最大和最小缩放级别maxZoom和minZoom已达到您的需求：

Comments

哎。。8.1才有呢- -

---

而且..我想要的效果是..让缩放控件的最底部，也就是最小值不是从0开始，而是从第9级开始..

---

您也可以通过设定最大与最小比例尺属性maxScale和minScale的方法来，wmts的<ScaleDenominator>表示的就是对应层级所对应的比例尺。当您设定了最大与最小比例尺后，您的地图缩放空间也会随之变化最大与最小级别的。

---

不行哦..minScale minResolution minZoom...都试过了...设置了后，切片的row和col不对了

Answer 2

您好！如果只想显示9-18级，客户端对接的时候  resolutions 数组里面只添加9-18级的就可以了！

var matrixIds = [];
    for (var i=0; i<10; i++) {
        matrixIds[i] = {identifier:(i+9)};
    };
    //当前图层的分辨率数组信息,和matrixIds一样，需要用户从wmts服务获取并明确设置,resolutions数组和matrixIds数组长度相同
    var resolutions = [
                                            // 2.9582935545456576E8,1.4791467772728288E8,7.395733886364144E7,

    //新建图层
    var url="http://xx.xx.xx.xx:8081/geoesb/proxy/d9dedf3b39b34fb0b5b3b4cb2855d0f2/f69b96a249cb42f59532abc1e53668ba";
    baseLayerSl = new SuperMap.Layer.WMTS({name: "CQMap_VEC",
        url: url,
        layer: "CQMap_VEC",
        style: "default",
        matrixSet: "CQMap_VEC",
        // matrixIds:matrixIds,
        // resolutions:resolutions,
        // tileFullExtent:new SuperMap.Bounds(104.988424239, 28.098457895, 108.973788561, 30.686177091),
        //tileOrigin:new SuperMap.LonLat(-180.0, 90.0),
        //zoomOffset:-1,
        format: "image/png",
        opacity: 1,
        requestEncoding:"KVP"});
    map.addLayers([baseLayerSl]);

我是这样写的。。显示不出来..

我按照你的方式写是可以的呀，你是不是因为把下面注释掉了

---

我搞错了。把比例尺写成resolutions了
