nearestVertices
(geometry, inputPoint, searchRadius, maxVertexCountToReturn)
{Promise<NearestPointResult>}
查找距指定點給定距離內的所有頂點,從最近到最遠排序,並將它們作為對象數組返回。
參數:
類型 說明 geometry Geometry要考慮的幾何形狀。
inputPoint Point測量的起點。
searchRadius Number以視圖的空間參考為單位從 inputPoint 搜索的距離。
maxVertexCountToReturn Number返回的最大頂點數。
返回:
類型 說明 Promise<NearestPointResult> 解析為 NearestPointResult 的數組,其中包含距離 inputPoint
最近的頂點。例子:
// Returns an array of the nearest vertices const nearest = await geometryEngineAsync.nearestVertices(boundaryPolygon, point, 500, 2);
