The default parameters to include in the WMS URL to obtain images. The values are as follows: service=WMS version=1.1.1 request=GetMap styles= format=image/jpeg

static constant Cesium.WebMapServiceImageryProvider.GetFeatureInfoDefaultParameters : object
engine/Source/Scene/WebMapServiceImageryProvider.js 636

The default parameters to include in the WMS URL to get feature information. The values are as follows: service=WMS version=1.1.1 request=GetFeatureInfo

clock : Clock
engine/Source/Scene/WebMapServiceImageryProvider.js 492

Gets or sets a clock that is used to get keep the time used for time dynamic parameters.

readonly credit : Credit
engine/Source/Scene/WebMapServiceImageryProvider.js 446

Gets the credit to display when this imagery provider is active. Typically this is used to credit the source of the imagery.

enablePickFeatures : boolean
engine/Source/Scene/WebMapServiceImageryProvider.js 478

Gets or sets a value indicating whether feature picking is enabled. If true, WebMapServiceImageryProvider#pickFeatures will invoke the GetFeatureInfo service on the WMS server and attempt to interpret the features included in the response. If false, WebMapServiceImageryProvider#pickFeatures will immediately return undefined (indicating no pickable features) without communicating with the server. Set this property to false if you know your data source does not support picking features or if you don't want this provider's features to be pickable.
默认值: true

readonly errorEvent : Event
engine/Source/Scene/WebMapServiceImageryProvider.js 433

Gets an event that is raised when the imagery provider encounters an asynchronous error. By subscribing to the event, you will be notified of the error and can potentially recover from it. Event listeners are passed an instance of TileProviderError.

readonly getFeatureInfoUrl : Resource|string
engine/Source/Scene/WebMapServiceImageryProvider.js 522

Gets the getFeatureInfo URL of the WMS server.

readonly hasAlphaChannel : boolean
engine/Source/Scene/WebMapServiceImageryProvider.js 462

Gets a value indicating whether or not the images provided by this imagery provider include an alpha channel. If this property is false, an alpha channel, if present, will be ignored. If this property is true, any images without an alpha channel will be treated as if their alpha is 1.0 everywhere. When this property is false, memory usage and texture upload time are reduced.

readonly layers : string
engine/Source/Scene/WebMapServiceImageryProvider.js 333

Gets the names of the WMS layers, separated by commas.

readonly maximumLevel : number|undefined

Gets the proxy used by this provider.

readonly rectangle : Rectangle
engine/Source/Scene/WebMapServiceImageryProvider.js 405

Gets the rectangle, in radians, of the imagery provided by this instance.

readonly tileDiscardPolicy : TileDiscardPolicy
engine/Source/Scene/WebMapServiceImageryProvider.js 419

Gets the tile discard policy. If not undefined, the discard policy is responsible for filtering out "missing" tiles via its shouldDiscardImage function. If this function returns undefined, no tiles are filtered.

readonly tileHeight : number
engine/Source/Scene/WebMapServiceImageryProvider.js 357

Gets the height of each tile, in pixels.

readonly tileWidth : number
engine/Source/Scene/WebMapServiceImageryProvider.js 345

Gets the width of each tile, in pixels.

readonly tilingScheme : TilingScheme
engine/Source/Scene/WebMapServiceImageryProvider.js 393

Gets the tiling scheme used by this provider.

times : TimeIntervalCollection
engine/Source/Scene/WebMapServiceImageryProvider.js 507

Gets or sets a time interval collection that is used to get time dynamic parameters. The data of each TimeInterval is an object containing the keys and values of the properties that are used during tile requests.

readonly url : string
engine/Source/Scene/WebMapServiceImageryProvider.js 309

Gets the URL of the WMS server.

方法

getTileCredits(x, y, level) → Array.<Credit>
engine/Source/Scene/WebMapServiceImageryProvider.js 537

Gets the credits to be displayed when a given tile is displayed.
参数名称 类型 描述信息
x number The tile X coordinate.

Initialization options for the WebMapServiceImageryProvider constructor
属性:
属性名称 类型 可选 默认值 描述信息
url Resource | string The URL of the WMS service. The URL supports the same keywords as the UrlTemplateImageryProvider.
layers string The layers to include, separated by commas.
parameters object <可选>
 WebMapServiceImageryProvider.DefaultParameters Additional parameters to pass to the WMS server in the GetMap URL.
getFeatureInfoParameters object <可选>
 WebMapServiceImageryProvider.GetFeatureInfoDefaultParameters Additional parameters to pass to the WMS server in the GetFeatureInfo URL.
enablePickFeatures boolean <可选>
 true If true, WebMapServiceImageryProvider#pickFeatures will invoke the GetFeatureInfo operation on the WMS server and return the features included in the response. If false, WebMapServiceImageryProvider#pickFeatures will immediately return undefined (indicating no pickable features) without communicating with the server. Set this property to false if you know your WMS server does not support GetFeatureInfo or if you don't want this provider's features to be pickable. Note that this can be dynamically overridden by modifying the WebMapServiceImageryProvider#enablePickFeatures property.
