Create(String,Boolean) Method

Creates a new HVDatumTransformation instance with the given well-known text and direction, and adds it to a new CompositeHVDatumTransformation instance.

Syntax

C#
Visual Basic (Declaration)

public static CompositeHVDatumTransformation Create( 
   string wkt,
   bool transformForward
)

Public Overloads Shared Function Create( _
   ByVal wkt As String, _
   Optional ByVal transformForward As Boolean _
) As CompositeHVDatumTransformation

Parameters

wkt: The well-known text of the geographic transformation to be created and added.
transformForward: (Optional) Default is true. If false, the created geographic transformation is inverted.

Return Value

A new composite geographic transformation that contains the created hv datum transformation.

Exceptions

Exception	Description
System.ArgumentException	The wkt is null or invalid.

Example

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();
CompositeHVDatumTransformation xml_compositehv = CompositeHVDatumTransformation.CreateFromXML(xml);

// create from json
string json = compositehv.ToJson();
CompositeHVDatumTransformation json_compositehv = DatumTransformation.CreateFromJson(json) as CompositeHVDatumTransformation;

Requirements

Target Platforms: Windows 10, Windows 8.1, Windows 7
