메소드 설명
Inverse ( ) : IMathTransform

Creates the inverse transform of this object.

This method may fail if the transform is not one to one. However, all cartographic projections should succeed.

Invert ( ) : void

Reverses the transformation
Transform ( SharpMap point ) : SharpMap.Geometries.Point

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.
