ESRI.ArcGIS.ADF.IMS.Carto Namespace > MapView Class > Draw Method : Draw(SpatialReference) Method

Visual Basic (Declaration)

Visual Basic (Usage)

C#

newSpatialReference: Spatial reference to use when drawing the map.

Redraws the map with new spatial reference properties.

Syntax

Visual Basic (Declaration)
Public Overloads Overrides Function Draw( _ ByVal newSpatialReference As SpatialReference _ ) As CartoImage

Visual Basic (Usage)	Copy Code
`Dim instance As MapView Dim newSpatialReference As SpatialReference Dim value As CartoImage value = instance.Draw(newSpatialReference)`

C#
public override CartoImage Draw( SpatialReference newSpatialReference )

Parameters

newSpatialReference: Spatial reference to use when drawing the map.

Return Value

CartoImage object, whose Url property contains the URL location of the map image.

Example

The following example draws the map with a new spatial reference set to the Robinson projection. It sets the map extent using a geographic coordinate system (4326). It assumes a MapView exists named mapView, and an image control in the page named imgMap.
