コード スニペット

以下のコード スニペットは、IgrArcGISOnlineMapImagery クラスを使用して IgrGeographicMap で Esri 画像サーバーからの React 地理的画像タイルを表示する方法を示します。

import { IgrGeographicMap } from 'igniteui-react-maps';
import { IgrArcGISOnlineMapImagery } from 'igniteui-react-maps';
// ...
const tileSource = new IgrArcGISOnlineMapImagery();
tileSource.mapServerUri = "https://services.arcgisonline.com/ArcGIS/rest/services/Ocean_Basemap/MapServer";

const geoMap = new IgrGeographicMap({ name: "geoMap" });
geoMap.backgroundContent = tileSource;
ts

Esri ユーティリティ

また、Esri 画像サーバーのすべてのスタイルを定義する EsriUtility を使用することもできます。

import { IgrGeographicMap } from 'igniteui-react-maps';
import { IgrArcGISOnlineMapImagery } from 'igniteui-react-maps';
import { EsriUtility, EsriStyle } from './EsriUtility';
// ...
const tileSource = new IgrArcGISOnlineMapImagery();
tileSource.mapServerUri = EsriUtility.getUri(EsriStyle.WorldOceansMap);

const geoMap = new IgrGeographicMap({ name: "geoMap" });
geoMap.backgroundContent = tileSource;
