normalizeUtils | API Reference | ArcGIS Maps SDK for JavaScript 4.31

Method Overview

Name	Return Type	Summary	Object
	Extent	Returns an extent over the dateline that is smaller than the normalized width if it visually contains the geometry.	normalizeUtils
	Promise<Geometry []>	Normalizes geometries that intersect the central meridian or fall outside the world extent so they stay within the coordinate system of the view.	normalizeUtils

Method Details

getDenormalizedExtent Method getDenormalizedExtent(geometry){Extent} Since: ArcGIS Maps SDK for JavaScript 4.21 normalizeUtils since 4.3, getDenormalizedExtent added at 4.21.

Returns an extent over the dateline that is smaller than the normalized width if it visually contains the geometry. The input geometry must be normalized and its spatialReference must be Web Mercator or WGS84.

Parameter

geometry Geometry

The geometry used to create the denormalized extent. The geometry should be a polygon, polyline, or a multipoint geometry. This method returns null if a point or a multipoint with only one point is used as the input geometry. It returns a cloned extent if an extent is used as the input geometry.

Returns

Type	Description
Extent	The denormalized extent. The new extent is either the same as the normal extent of the geometry or a smaller extent.

Example

// create an extent that goes over the dateline
// as the points are cross the dateline
const multipoint = new Multipoint({
  points: [
    [158.6082458495678, 59.91028747107214],
    [-145.98220825200923, 60.23981116998903]
  ]
});
const extent = normalizeUtils.getDenormalizedExtent(multipoint);

normalizeCentralMeridian Method normalizeCentralMeridian(geometries, url, requestOptions){Promise<Geometry[]>}

Normalizes geometries that intersect the central meridian or fall outside the world extent so they stay within the coordinate system of the view. Only supported for Web Mercator and WGS84 spatial references.

Parameters

geometries Geometry []

An array of geometries to normalize.

url String

optional

A geometry service URL used to perform the normalization. If this value is null then the default geometry service URL in esriConfig.geometryServiceUrl is used.

requestOptions Object

optional

Additional options to be used for the data request.

Returns

Type	Description
Promise<Geometry []>	Resolves to an array of the normalized geometries.

Example

// create a non-normalized line that crosses the dateline
const polyline = new Polyline({
  paths: [
    [170, 52.68],
    [190, 49.5]
  ]
});

normalizeUtils.normalizeCentralMeridian([polyline])
  .then(function(polylines){
    // returns a line representing the same geometry, but
    // now is normalized between -180 and 180 on the x-coordinate.
    // but represents the same feature
    const graphic = new Graphic({
      geometry: polylines[0],
      symbol: { type: "simple-line" }
    });
