C# Класс MapAround.CoordinateSystems.Transformations.Gnomonic

Implements a gnomonic projection. Gnomonic projection is used to bring the topological problems in the sphere to the problems on the plane. This reduction is possible if the envelope of data is less than a hemisphere.

Метод	Описание
Gnomonic ( ) : System	Initializes a new instance of the MapAround.CoordinateSystems.Transformations.Gnomonic. Center (contact point) is the North Pole.
Gnomonic ( double centerLongitude, double centerLatitude ) : System	Initializes a new instance of the MapAround.CoordinateSystems.Transformations.Gnomonic.
Inverse ( ) : IMathTransform	Creates the inverse transform of this object.
Invert ( ) : void	Inverts this transform.
Transform ( double point ) : double[]	Transforms a coordinate point. The passed parameter point should not be modified.
TransformList ( List points ) : List	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.

TransformList() публичный Метод

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.

public TransformList ( List points ) : List
points	List	Packed ordinates of points to transform
Результат	List
