Visual Basic (Declaration)

Visual Basic (Usage)

C#

screenRectangle

transformationParameters

Converts screen rectangle into a map envelope.

Syntax

Visual Basic (Declaration)
Public Overloads Shared Function ToMapEnvelope( _ ByVal screenRectangle As Rectangle, _ ByVal transformationParameters As TransformationParams _ ) As Envelope

Visual Basic (Usage)	Copy Code
Dim screenRectangle As Rectangle Dim transformationParameters As TransformationParams Dim value As Envelope value = Envelope.ToMapEnvelope(screenRectangle, transformationParameters)

C#
public static Envelope ToMapEnvelope( Rectangle screenRectangle, TransformationParams transformationParameters )

Parameters

screenRectangle
transformationParameters

Return Value

The map envelope.

Example

This example converts a screen rectangle to an envelope in map coordinates.

C#	Copy Code
// Create rectangle (x, y, width, height) System.Drawing.Rectangle screenRectangle = new System.Drawing.Rectangle(35, 125, 200, 200); // Get transformation parameters from the Map control ESRI.ArcGIS.ADF.Web.Geometry.TransformationParams transParams = Map1.GetTransformationParams( ESRI.ArcGIS.ADF.Web.Geometry.TransformationDirection.ToMap); ESRI.ArcGIS.ADF.Web.Geometry.Envelope mapEnvelope = ESRI.ArcGIS.ADF.Web.Geometry.Envelope.ToScreenRectangle( screenRectangle);

Copy Code

// Create rectangle (x, y, width, height)
System.Drawing.Rectangle screenRectangle =
    new System.Drawing.Rectangle(35, 125, 200, 200);
 
// Get transformation parameters from the Map control
ESRI.ArcGIS.ADF.Web.Geometry.TransformationParams transParams =
    Map1.GetTransformationParams(
    ESRI.ArcGIS.ADF.Web.Geometry.TransformationDirection.ToMap);
 
ESRI.ArcGIS.ADF.Web.Geometry.Envelope mapEnvelope =
    ESRI.ArcGIS.ADF.Web.Geometry.Envelope.ToScreenRectangle(
    screenRectangle);

Visual Basic	Copy Code
' Create rectangle (x, y, width, height) Dim screenRectangle As New System.Drawing.Rectangle(35, 125, 200, 200) ' Get transformation parameters from the Map control Dim transParams As ESRI.ArcGIS.ADF.Web.Geometry.TransformationParams = _ Map1.GetTransformationParams( _ ESRI.ArcGIS.ADF.Web.Geometry.TransformationDirection.ToMap) Dim mapEnvelope As ESRI.ArcGIS.ADF.Web.Geometry.Envelope = _ ESRI.ArcGIS.ADF.Web.Geometry.Envelope.ToScreenRectangle( _ screenRectangle)

Visual Basic

Copy Code

' Create rectangle (x, y, width, height)
Dim screenRectangle As New System.Drawing.Rectangle(35, 125, 200, 200)
 
' Get transformation parameters from the Map control
Dim transParams As ESRI.ArcGIS.ADF.Web.Geometry.TransformationParams = _
    Map1.GetTransformationParams( _
    ESRI.ArcGIS.ADF.Web.Geometry.TransformationDirection.ToMap)
 
Dim mapEnvelope As ESRI.ArcGIS.ADF.Web.Geometry.Envelope = _
    ESRI.ArcGIS.ADF.Web.Geometry.Envelope.ToScreenRectangle( _
    screenRectangle)

Remarks

Use this form of the method instead of the other forms of ToMapEnvelope in order to account for rotation of the Map. The TransformationParams may be obtained from the Map with Map.GetTransformationParams.
