| Name | Summary |
|---|---|
| new GeneralizeParameters() | Creates a new GeneralizeParameters object. |
Properties
| Name | Type | Summary |
|---|---|---|
| deviationUnit | Number | String | The maximum deviation unit. |
| geometries | Geometry[] | The array of input geometries to generalize. |
| maxDeviation | Number | The maximum deviation for constructing a generalized geometry based on the input geometries. |
Constructor Details
Creates a new GeneralizeParameters object. The constructor takes no parameters
Sample:
require([
"esri/tasks/GeneralizeParameters", ...
], function(GeneralizeParameters, ... ) {
var generalizeParams = new GeneralizeParameters();
...
});
Property Details
The maximum deviation unit. If the unit is not specified, units are derived from the spatial reference. See the constants table of GeometryService for a list of valid values.
<Geometry[]
Geometry[]The array of input geometries to generalize. All geometries in this array must be of the same geometry type (esriGeometryPolyline or esriGeometryPolygon).
Sample:
require([
"esri/tasks/GeneralizeParameters", "dojo/_base/array", ...
], function(GeneralizeParameters, array, ... ) {
var generalizeParams = GeneralizeParameters();
var geoms = array.map(featureSet.features,function(feature){
return feature.geometry;
});
generalizeParams.geometries = geoms;
...
});
<Number
NumberThe maximum deviation for constructing a generalized geometry based on the input geometries.
Sample:
generalizeParams.maxDeviation = 0.05;
