public String getGeometryType()
WebGeometry
Returns a text representing the type of the geometry. WebGeometry
objects of the same type must return
the same text.

WebGeometry
Converts a geometry in screen coordinates to a geometry of the same type in map coordinates. The coordinate system
of the converted geometry is the same as the coordinate system of the WebMap
.

- The WebMap
based on which the coordinates need to be converted
WebGeometry
in map coordinatespublic WebPolyline toMapGeometry(WebExtent extent, int width, int height)
WebGeometry
Converts a geometry in screen coordinates to a geometry of the same type in map coordinates. The coordinate system of the converted geometry is the same as the coordinate system of the specified extent.
toMapGeometry
in class WebGeometry
extent
- the WebExtent
of the map imagewidth
- the width of the map imageheight
- the height of the map image
WebGeometry
in map coordinatespublic WebPolyline fromMapGeometry(WebMap webMap)
WebGeometry
Converts a geometry in map coordinates to a geometry of the same type in screen coordinates. Since the converted
geometry is a screen geometry, the coordinate system of the converted geometry will be null
.

WebGeometry
Converts a geometry in map coordinates to a geometry of the same type in screen coordinates. Since the converted
geometry is a screen geometry, the coordinate system of the converted geometry will be null
.

public WebPolyline project(WebSpatialReference toSpatialReference)
WebGeometry
Converts the geometry in map coordinates from the spatialReference
of this geometry to a geometry in
the desired spatial reference. If the desired spatial reference is same as that of this geometry, this same
geometry is returned. Otherwise, a new WebGeometry
object is created and populated with the converted
coordinates. The type of the projected geometry is same as this geometry.
