public class ProjectiveTransformation2D
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, ITransformationGEN, IProjectiveTransformation2DGEN, ITransformation, IProjectiveTransformation2D, IClone, ISupportErrorInfo

A two dimensional projective transformation.

Description

The projective transformation requires a minimum of four points to define the transformation. The projective transformation is only used to transform coordinates digitized directly off high altitude aerial photography or aerial photographs of relatively flat terrain assuming that there is no systematic distortion in the air photos. The projective transformation uses eight parameters.

ProjectiveTransformation2D is defined by the matrix operations necessary for

X = (ax + by + c) / (gx + hy + 1)


Y = (dx + ey + f )/ (gx + hy + 1)
