Redraws the map with the specified map Extent.

Syntax

Visual Basic (Declaration)
Public Overloads Overridable Function Draw( _ ByVal newExtent As Envelope _ ) As CartoImage

Visual Basic (Usage)	Copy Code
`Dim instance As View Dim newExtent As Envelope Dim value As CartoImage value = instance.Draw(newExtent)`

C#
public virtual CartoImage Draw( Envelope newExtent )

New map image with input extent, in the form of a CartoImage object. Use CartoImage.Url to retrieve the image's URL.

Example

This example defines a new envelope and uses it in drawing the map.

C#	Copy Code
`Envelope newExtent = new Envelope(10, 30, 30, 50); CartoImage resultImage = mapView.Draw(newExtent); imgMap.ImageUrl = resultImage.Url;`

Visual Basic	Copy Code
`Dim newExtent As New Envelope(10, 30, 30, 50) Dim resultImage As CartoImage = mapView.Draw(newExtent) imgMap.ImageUrl = resultImage.Url`

This method draws the map with the envelope specified. The exact envelope drawn may be modified to fit the aspect ratio of the map image pixel size.

Any Zoom, Pan, CenterAt or Draw method which changes the map extent also changes the map extent for the MapView.
