Interface esriTransformDirection

All Superinterfaces:

public interface esriTransformDirection
extends Serializable

Specifies whether to apply a forward or reverse (inverse) transformation.


The definition of many transformations, particularly geographic (datum) transformations, include a specific direction. For example, you might define a transformation that converts from WGS 1972 to WGS 1984. The transformation parameters are defined to convert "FROM" WGS 1972 "TO" WGS 1984. If you use the esriTransformDirection enumeration value to esriTransformReverse, you can apply the transformation in the opposite direction (from WGS 1984 to WGS 1972).
