Public Methods

Method	Description
GeocentricTransform ( List parameters, bool isInverse ) : System	Initializes a geocentric projection object
Inverse ( ) : IMathTransform	Returns the inverse of this conversion.
Invert ( ) : void	Reverses the transformation
Transform ( double point ) : double[]	Transforms a coordinate point. The passed parameter point should not be modified.
TransformList ( IList points ) : IList
TransformList ( IList points ) : IList	Transforms a list of coordinate point ordinal values. This method is provided for efficiently transforming many points. The supplied array of ordinal values will contain packed ordinal values. For example, if the source dimension is 3, then the ordinals will be packed in this order (x0,y0,z0,x1,y1,z1 ...). The size of the passed array must be an integer multiple of DimSource. The returned ordinal values are packed in a similar way. In some DCPs. the ordinals may be transformed in-place, and the returned array may be the same as the passed array. So any client code should not attempt to reuse the passed ordinal values (although they can certainly reuse the passed array). If there is any problem then the server implementation will throw an exception. If this happens then the client should not make any assumptions about the state of the ordinal values.

Private Methods

Method	Description
DegreesToMeters ( double lonlat ) : double[]	Converts coordinates in decimal degrees to projected meters.
GeocentricTransform ( List parameters ) : System	Initializes a geocentric projection object
MetersToDegrees ( double pnt ) : double[]	Converts coordinates in projected meters to decimal degrees.

Method Details

GeocentricTransform() public method

Initializes a geocentric projection object

public GeocentricTransform ( List parameters, bool isInverse ) : System
parameters	List	List of parameters to initialize the projection.
isInverse	bool	Indicates whether the projection forward (meters to degrees or degrees to meters).
return	System

Inverse() public method

Returns the inverse of this conversion.

public Inverse ( ) : IMathTransform
return	IMathTransform

Invert() public method

Reverses the transformation

public Invert ( ) : void
return	void

Transform() public method

Transforms a coordinate point. The passed parameter point should not be modified.

public Transform ( double point ) : double[]
point	double
return	double[]

TransformList() public method

public TransformList ( IList points ) : IList
points	IList
return	IList

TransformList() public method

Transforms a list of coordinate point ordinal values.

This method is provided for efficiently transforming many points. The supplied array of ordinal values will contain packed ordinal values. For example, if the source dimension is 3, then the ordinals will be packed in this order (x0,y0,z0,x1,y1,z1 ...). The size of the passed array must be an integer multiple of DimSource.
