Example

In This Topic
    GetInverse Method (CompositeHVDatumTransformation)
    In This Topic
    Creates an inverted instance of this HVDatumTransformation. The inverted instance has inverted order of HVDatumTransformation instances, and each hv datum transformation has its IsForward property inverted.
    Syntax
    public override DatumTransformation GetInverse()
    Public Overrides NotOverridable Function GetInverse() As DatumTransformation

    Return Value

    A DatumTransformation that is inverted.
    Example
    Create Composite HV Datum Transformation
    HVDatumTransformation hv1 = HVDatumTransformation.Create(108034);
    HVDatumTransformation hv2 = HVDatumTransformation.Create(108033, false);
    List<HVDatumTransformation> hvs = new List<HVDatumTransformation>() { hv1, hv2 };
    
    // create from enumeration
    CompositeHVDatumTransformation compositehv = 
                    CompositeHVDatumTransformation.Create(hvs);
    int count = compositehv.Count;      // count = 2
    
    List<HVDatumTransformation> transforms = 
                   compositehv.Transformations as List<HVDatumTransformation>;
    HVDatumTransformation tranform = transforms[0];
    // transform.Wkid = 108034
    
    // get inverse
    CompositeHVDatumTransformation inverse_compositehv = 
           compositehv.GetInverse() as CompositeHVDatumTransformation;
    
    // create from xml
    string xml = compositehv.ToXml();
    //At 2.x - CompositeHVDatumTransformation xml_compositehv =
    //      CompositeHVDatumTransformation.CreateFromXML(xml);
    
    var xml_compositehv = CompositeHVDatumTransformation.CreateFromXml(xml);
    
    // create from json
    string json = compositehv.ToJson();
    CompositeHVDatumTransformation json_compositehv = 
        DatumTransformation.CreateFromJson(json) as CompositeHVDatumTransformation;
