ITopologyGraph.TransformSelection Method

Applies the specified transformation to the selected elements of the graph.

[Visual Basic .NET]
Public Sub TransformSelection ( _
    ByVal Direction As esriTransformDirection, _
    ByVal transformation As ITransformation, _
    ByVal proportionalStretch As Boolean _
public void TransformSelection (
    esriTransformDirection Direction,
    ITransformation transformation,
    bool proportionalStretch
HRESULT TransformSelection(
  esriTransformDirection Direction,
  ITransformation* transformation,
  VARIANT_BOOL proportionalStretch



  Direction is a parameter of type esriTransformDirection


  transformation is a parameter of type ITransformation

proportionalStretch   proportionalStretch is a parameter of type VARIANT_BOOL

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.


This method modifies the selected TopologyElements using an ITransformation reference. It can be used to move a point or to apply more advanced coordinate transformations such as Conformal, Affine or Projective transformations. For example, it can be used to adjust a polygon using control points without breaking the adjacency with other polygons.
