ArcGIS JS，服务范围（光栅）

我正在使用

ArcGisDynamicMapsServiceLayer从服务创建一个层

layerServicios = new esri.layers.ArcGISDynamicMapServiceLayer(service_url, {
    id: id_layer,
    opacity: 0.9,
    imageParameters: imageParams
});
console.log('layerServicios', layerServicios):

maxRecordCount: 1000000000
maxScale: 0
minScale: 0
normalization: true
onError: ƒ ()
onLoad: ƒ ()
onOpacityChange: ƒ ()
etc...
}

当我使用graphic layer时，我在缩放到范围方面没有问题：

var gLayer = map.getLayer(id_layer);
var ge = GraphicsUtils.graphicsExtent(gLayer.graphics);
map.setExtent(ge, true);

但现在我不知道如何设置范围在这种情况下，使用服务返回光栅
您可以使用

map.setExtent(rasterLayer.fullExtent);
