Interface ICompositeGeoTransformation

All Superinterfaces:

IGeoTransformation, ITransformation, Serializable

All Known Implementing Classes:

CompositeGeoTransformation

public interface ICompositeGeoTransformation
extends IGeoTransformation, Serializable

Provides access to members that control a set of geographic transformations.

Description

Sometimes it is necessary to transform between two geographic coordinate systems where a direct transformation does not exist. A composite geotransformation allows you to create a 'chain' of existing or custom transformations. Each transformation in the set must have its direction set properly.

Remarks

Of the ITransformation interface, only the TransformPointsFF method is implemented.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Method Summary

void	add(int direction, IGeoTransformation pXForm) Adds a geographic transformation to the list.
int	getCount() The number of geographic transformations in the list.
IGeoTransformation	getGeoTransformation(int i) A geographic transformation from the list.
int	getTransformationDirection(int i) The direction (forward/reverse) of a geographic transformation.
void	setEmpty() Clears the list of geographic transformations from the object.
