Property Details
-
Since: ArcGIS API for JavaScript 4.7
-
The name of the class. The declared class name is formatted as
esri.folder.className.
-
The input geometries to project.
-
outSpatialReference SpatialReferenceSince: ArcGIS API for JavaScript 4.4
-
The spatial reference to which you are projecting the geometries.
-
transformation Object
-
The well-known id {wkid:number} or well-known text {wkt:string} of the datum transformation to be applied to the projected geometries. See Datum transformations for a list of valid datum transformations that may be used here.
If a transformation is specified, a value must also be specified in the transformForward property.
- Properties:
-
optionalwkid Number
The well-known ID of the datum transformation to apply to the projection. List of valid IDs for Datum transformations.
optionalwkt StringThe well-known text that defines a spatial reference. Many browsers have a limit to the length of a GET request of approximately 2048 characters. When using well-known text to specify the spatial reference you can easily exceed this limit. In these cases, you will need to setup and use a proxy page.
-
transformForward Boolean
-
Indicates whether to transform forward or not. The forward or reverse direction of transformation is implied in the name of the transformation.
