Question

ArcGIS API for JavaScript。使用WMS地图服务，放大缩小地图会偏移。请高手请教

map = new esri.Map(obj, {
logo: false,
nav: false
});
//service=WMS&request=GetCapabilities
var resourceInfo = {
extent: new esri.geometry.Extent(480000, 3486821, 535900, 3524616, { wkid: 0 }),
layerInfos: [new esri.layers.WMSLayerInfo({ name: "baseLyr", title: "csvector" })]
};
//minx miny maxx maxy
var wmsLayer = new esri.layers.WMSLayer("http://192.168.4.20/WMS/ArcGIS/csvector.gis",
{ resourceInfo: resourceInfo,
visibleLayers: ["baseLyr"], id:"wmsl"
}
);
var yxtLayer = new esri.layers.WMSLayer("http://192.168.4.20/WMS/ArcGIS/cs2013dom.gis",
{ resourceInfo: resourceInfo,
visibleLayers: ["baseLyr"], id:"yxtl"
}
);
map.addLayer(wmsLayer);
map.addLayer(yxtLayer);
yxtLayer.hide();
