Interface ISplineXform

All Superinterfaces:

IGeodataXform, Serializable

All Known Implementing Classes:

SplineXform

public interface ISplineXform
extends IGeodataXform, Serializable

Provides access to members that control a Thin Plate Spline transform.

Remarks

The ISplineXform interface is used to create the SplineXform object from two sets of control points.

The SplineXform object performs a geodata transformation using a Spline function, a piecewise polynomial that maintains continuity and smoothness between adjacent polynomials. It transforms the source control points exactly to the target control points, while the points or pixels that are away from the control points are not always guaranteed to have higher accuracy. Spline transformation is useful when the control points are very important and required to be registered precisely. Adding more control points can increase an overall accuracy of the Spline transformation.
