GeoArcGisMapServerImageryProvider

new Cesium.GeoArcGisMapServerImageryProvider(options)

自定义arcgis地图provider，支持缓存服务和动态服务，支持坐标系①WGS84经纬度②CGCS2000经纬度③高斯投影坐标系。
Name Type Description
options Object 参数选项
Name Type Default Description
url Resource | String optional arcgis地图服务的url
token String optional arcgis token
tileDiscardPolicy TileDiscardPolicy optional 一个决定瓦片是否合法是否需要丢弃的策略。
usePreCachedTilesIfAvailable Boolean true optional 如果为true，则使用缓存服务，如果为false，则使用'export'服务
layers String optional 要显示的图层，以逗号分隔，如'2,3,4'。如果不指定，即为undefined，则显示所有图层
enablePickFeatures Boolean true optional 是否拾取要素
rectangle Rectangle Rectangle.MAX_VALUE optional 图层范围
tilingScheme TilingScheme new GeographicTilingScheme() optional 切片方案
credit Credit | String optional A credit for the data source
tileWidth Number 256 optional 瓦片宽度
tileHeight Number 256 optional 瓦片高度
maximumLevel Number optional 请求服务的最大层级
bboxSR Number optional export服务的包围盒的空间参考
imageSR Number optional export服务的输出图片的空间参考，如无特殊情况则与bboxSR保持一致。如果与数据源空间参考一致，则不做动态投影，如果不一致则做动态投影 比如数据源空间参考是4550，如果欲做动态投影，则设置4326；如果不做动态投影，则设置4550即可。如果数据源空间参考是wkt定义的话，可不设置。
parameters Object optional 传递给服务的附加参数
antiPreMultiplyAlpha Boolean false optional 是否取消预乘，默认false。如果为true的话，可以解决渲染栅格瓦片黑边的问题。

staticCesium.GeoArcGisMapServerImageryProvider.getInstanceByCapabilities(options) → Promise

通过请求服务元信息创建GeoArcGisMapServerImageryProvider
Name Type Description
options Object 参数选项：
Name Type Description
viewer Viewer optional 三维球对象
url Resource | String 服务地址
parameters Object optional 传递给服务的附加参数
Returns:
如果请求元信息成功，则创建Provider
Example:
var promise = Cesium.GeoArcGisMapServerImageryProvider.getInstanceByCapabilities({
 viewer: viewer,
 url: 'https://192.168.100.231:6443/arcgis/rest/services/MapService_Local/shenyang2/MapServer'
});
promise.then(function(provider) {
