Syntax

Visual Basic (Declaration)
Public Function ToScreenRectangle( _ ByVal transformationParams As TransformationParams _ ) As Rectangle

Visual Basic (Usage)	Copy Code
Dim instance As Envelope Dim transformationParams As TransformationParams Dim value As Rectangle value = instance.ToScreenRectangle(transformationParams)

C#
public Rectangle ToScreenRectangle( TransformationParams transformationParams )

Parameters

transformationParams

Return Value

Screen-rectangle of converted map envelope.

Example

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

C#	Copy Code
ESRI.ArcGIS.ADF.Web.Geometry.Envelope mapEnvelope = new ESRI.ArcGIS.ADF.Web.Geometry.Envelope( 25.0, -4.5, 27.0, -6.5); // Get transformation parameters from the Map control ESRI.ArcGIS.ADF.Web.Geometry.TransformationParams transParams = Map1.GetTransformationParams( ESRI.ArcGIS.ADF.Web.Geometry.TransformationDirection.ToScreen); System.Drawing.Rectangle screenRectangle = mapEnvelope.ToScreenRectangle(transParams);

Copy Code

ESRI.ArcGIS.ADF.Web.Geometry.Envelope mapEnvelope =
    new ESRI.ArcGIS.ADF.Web.Geometry.Envelope(
    25.0, -4.5, 27.0, -6.5);
    
// Get transformation parameters from the Map control
ESRI.ArcGIS.ADF.Web.Geometry.TransformationParams transParams =
    Map1.GetTransformationParams(
    ESRI.ArcGIS.ADF.Web.Geometry.TransformationDirection.ToScreen);
    
System.Drawing.Rectangle screenRectangle =
    mapEnvelope.ToScreenRectangle(transParams);

Visual Basic	Copy Code
Dim mapEnvelope As New _ ESRI.ArcGIS.ADF.Web.Geometry.Envelope( _ 25.0, -4.5, 27.0, -6.5) ' Get transformation parameters from the Map control Dim transParams As ESRI.ArcGIS.ADF.Web.Geometry.TransformationParams = _ Map1.GetTransformationParams( _ ESRI.ArcGIS.ADF.Web.Geometry.TransformationDirection.ToScreen) Dim screenRectangle As System.Drawing.Rectangle = _ mapEnvelope.ToScreenRectangle(transParams)

Visual Basic

Copy Code

Dim mapEnvelope As New _
    ESRI.ArcGIS.ADF.Web.Geometry.Envelope( _
    25.0, -4.5, 27.0, -6.5)
    
' Get transformation parameters from the Map control
Dim transParams As ESRI.ArcGIS.ADF.Web.Geometry.TransformationParams = _
    Map1.GetTransformationParams( _
    ESRI.ArcGIS.ADF.Web.Geometry.TransformationDirection.ToScreen)
    
Dim screenRectangle As System.Drawing.Rectangle = _
    mapEnvelope.ToScreenRectangle(transParams)

Remarks

The transformationParams may be obtained from the Map with Map.GetTransformationParams.
