Parameters

graphics

The graphics used to calculate lengths.

lengthUnit

The length unit in which perimeters of polygons will be calculated. If unit is not specified, the units are derived from the Spatial Reference of the geometry.

geodesic

If polylines are in geographic coordinate system, then geodesic needs to be set to true in order to calculate the ellipsoidal shortest path distance between each pair of the vertices in the polylines. The output if lengthUnit is not specified is returned in meters.

userToken

A user-defined object that is passed to the method invoked.

Target Platforms: Windows XP Professional, Windows Server 2003 family, Windows Vista, Windows Server 2008 family
