扩展Arcgis flex api 读取WMTS 图层的方法 Extend API Application Source Code WMTS.mxml ?xml version=1.0 encoding=utf-8? s:Application xmlns:fx=/mxml/2009 xmlns:s=library:///flex/spark xmlns:esri=/2008/ags xmlns:samples=com.esri.ags.samples.* pageTitle=WMTS Layer !-- Description: This sample demonstrates how to add a Web Map Tile Service(WMTS) as a custom layer. The ArcGIS API for Flex allows for extending the API to access layer types not included as part of the API. In this example, the tiled layer (TiledMapServiceLayer) is extended to access WMTS tiles. Steps involved: 1. Creating new ActionScript class(WMTSLayer.as) that extends TiledMapServiceLayer. 2. Hardcoding some of the configuration settings: fullExtent, initialExtent, spatialReference, tileInfo, and units. 3. Overriding the protected function getTileURL() to obtain the appropriate tiles and place them accurately on the map. 4. Using the extended class with MXML or ActionScript :) Documentation: For more information, see the API documentation. /en/help/flex-api/apiref/com/esri/ags/Map.html /en/help/flex-api/apiref/com/esri/ags/SpatialReference.html /en/help/flex-api/apiref/com/esri/ags/geometry/Extent.html /en/help/flex-api/apiref/com/esri/ags/geometry/MapPoint.html /en/help/flex-api/apiref/com/esri/ags/geometry/WebMercatorExtent.html /en/help/flex-api/apiref/com/esri/ags/layers/ArcGISTiledMapServiceLayer.html /en/help/flex-api/apiref/com/esri/ags/layers/TiledMapServiceLayer.html /en/help/flex-api/apiref/com/esri/ags/layers/supportClasses/LOD.html /en/help/flex-api/apiref/com/esri/ags/layers/supportClasses/TileInfo.html /en/help/flex-api/concepts/index.html#/Types_of_layers/017p00000027000000/ This sample also uses the following files: com/esri/ags/samples/WMTSLayer.as -- fx:Script
