ArcGIS.Core.Geometry Namespace / CompositeGeographicTransformation Class / GetInverse Method
Example

In This Topic
    GetInverse Method (CompositeGeographicTransformation)
    In This Topic
    Creates an inverted instance of this tranformation. The inverted instance has inverted order of GeographicTransformation instances, and each geographic transofmration has its IsForward property inverted.
    Syntax
    public override DatumTransformation GetInverse()
    Public Overrides NotOverridable Function GetInverse() As DatumTransformation

    Return Value

    Example
    Create Composite Geographic Transformation
    // Create singleton from wkid
    CompositeGeographicTransformation cgt = 
        ArcGIS.Core.Geometry.CompositeGeographicTransformation.Create(108272);
    int count = cgt.Count;    // count = 1
    
    IList<GeographicTransformation> gts = cgt.Transformations 
                                    as IList<GeographicTransformation>;
    gts.Add(ArcGIS.Core.Geometry.GeographicTransformation.Create(1437, false));
    count = cgt.Count;        // count = 2
    
    // create from an enumeration
    CompositeGeographicTransformation another_cgt = 
                  ArcGIS.Core.Geometry.CompositeGeographicTransformation.Create(gts);
    GeographicTransformation gt0 = another_cgt[0];
    GeographicTransformation gt1 = another_cgt[1];
    
    // get the inverse
    CompositeGeographicTransformation inversed_cgt = another_cgt.GetInverse() as CompositeGeographicTransformation;
    // inversed_cgt[0] is same as gt1
    // inversed_cgt[1] is same as gt0
    
    var wkt = gt0.Wkt;
    // create from string 
    CompositeGeographicTransformation third_cgt = 
       ArcGIS.Core.Geometry.CompositeGeographicTransformation.Create(wkt, gt0.IsForward);
    count = third_cgt.Count;        // count = 1
    
    // create from josn
    string json = cgt.ToJson();
    CompositeGeographicTransformation joson_cgt = 
      DatumTransformation.CreateFromJson(json) as CompositeGeographicTransformation;
