ESRI.ArcGIS.ADF.Web.Geometry Namespace > Point Class > ToScreenPoint Method : ToScreenPoint(TransformationParams) Method

Visual Basic (Declaration)

Visual Basic (Usage)

C#

transformationParams: Information about the transformation, including map extent, size, projection and rotation, and whether the transformation is to map coordinates or to screen pixels.

Converts a point in map coordinates to a Point in screen coordinates (pixel coordinates).

Syntax

Visual Basic (Declaration)
Public Overloads Function ToScreenPoint( _ ByVal transformationParams As TransformationParams _ ) As Point

Visual Basic (Usage)	Copy Code
Dim instance As Point Dim transformationParams As TransformationParams Dim value As Point value = instance.ToScreenPoint(transformationParams)

C#
public Point ToScreenPoint( TransformationParams transformationParams )

Parameters

transformationParams: Information about the transformation, including map extent, size, projection and rotation, and whether the transformation is to map coordinates or to screen pixels.

Return Value

Screen-point (pixel-point) of converted map Point.

Example

This example converts a map point to screen point. It obtains the TransformationParams from the Map control, which is assumed to be available as Map1.

C#	Copy Code
ESRI.ArcGIS.ADF.Web.Geometry.Point mapPoint = new ESRI.ArcGIS.ADF.Web.Geometry.Point( -75.0, 35.0); // 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.Point screenPoint = mapPoint.ToScreenPoint(transParams);

Copy Code

ESRI.ArcGIS.ADF.Web.Geometry.Point mapPoint =
    new ESRI.ArcGIS.ADF.Web.Geometry.Point(
    -75.0, 35.0);
    
// 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.Point screenPoint =
    mapPoint.ToScreenPoint(transParams);

Visual Basic	Copy Code
Dim mapPoint As New _ ESRI.ArcGIS.ADF.Web.Geometry.Point( _ -75.0, 35.0) ' 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 screenPoint As System.Drawing.Point = _ mapPoint.ToScreenPoint(transParams)

Visual Basic

Copy Code

Dim mapPoint As New _
    ESRI.ArcGIS.ADF.Web.Geometry.Point( _
    -75.0, 35.0)
    
' 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 screenPoint As System.Drawing.Point = _
    mapPoint.ToScreenPoint(transParams)

Remarks

Use this form of the method instead of ToScreenPoint(Envelope, int, int) in order to account for rotation of the Map. The transformationParams may be obtained from the Map with Map.GetTransformationParams.
