Description
Method DefineFromControlPoints Defines the best projective transformation between two sets of points. Can be used to register paper maps on a digitizer.
Method GetControlPointError Returns the errors involved in moving control point i from the 'from' to 'to' system. These error terms are valid after using DefineFromControlPoints/Ex to define the transformation.
Method GetRMSError RMS (Root Mean Square) error expressed relative to the 'from' and 'to' points defining the transformation. These error terms are valid after using DefineFromControlPoints/Ex to define the transformation.
Method Project Moves this transformation into another spatial reference. If the transformations contains only translations, then use the MoveOrigin property to define an equivalent translation in the new spatial reference.
Method QueryTransformationParameters Returns the eight parameters which define the two dimensional projective transformation.
Method Reset Resets the tranformation.
Method SetTransformationParameters Sets the eight parameters which define the two dimensional projective transformation.
Read/write property SpatialReference The spatial reference in which this transformation is meaningful.
Method TransformMeasuresFF Transforms floating point measures to floating point measures (or do the inverse).
Method TransformMeasuresFI Transforms floating point measures to integer measures (or do the inverse).
Method TransformMeasuresIF Transforms integer measures to floating point measures (or do the inverse).
Method TransformMeasuresII Transforms integer measures to integer measures (or do the inverse).
Method TransformPointsFF Transforms floating point points to floating point points (or do the inverse).
Method TransformPointsFI Transforms floating point points to integer points (or do the inverse).
Method TransformPointsIF Transforms integer points to floating point points (or do the inverse).
Method TransformPointsII Transforms integer points to integer points (or do the inverse).

Inherited Interfaces

Interfaces Description
ITransformation Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on.
