對幾何體執行簡化操作,這會改變給定的幾何體以使其定義相對於其幾何體類型在拓撲上是合法的。在簡化操作結束時,不會出現多邊形環或折線路徑重疊,也不會出現 self-intersection。
參數:
類型 說明 geometry Geometry要簡化的幾何圖形。
返回:
類型 說明 Promise<Geometry> 解析後,響應是簡化的幾何圖形。 例子:
// Topologically simplifies a geometry const simplified = await geometryEngineAsync.simplify(polyline); console.log(geometryEngine.isSimple(simplified)); // true
基本信息
以下是所在類或對象的基本信息。
AMD:
require(["esri/geometry/geometryEngineAsync"], (geometryEngineAsync) => { /* code goes here */ });
ESM:
import * as geometryEngineAsync from "@arcgis/core/geometry/geometryEngineAsync";
