IProjectiveTransformation2DGEN Interface

Provides access to members that define and manipulate projective transformations. IProjectiveTransformation2DGEN is generic version of IProjectiveTransformation.

Members

	Name	Description
	DefineFromControlPoints	Defines the best projective transformation between two sets of points. Can be used to register paper maps on a digitizer.
	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.
	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.
	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.
	QueryTransformationParameters	Returns the eight parameters which define the two dimensional projective transformation.
	Reset	Resets the tranformation.
	SetTransformationParameters	Sets the eight parameters which define the two dimensional projective transformation. The size of the incoming parameter array needs to be 8.
	SpatialReference	The spatial reference in which this transformation is meaningful.
	TransformMeasuresFF	Transforms floating point measures to floating point measures (or do the inverse).
	TransformMeasuresFI	Transforms floating point measures to integer measures (or do the inverse).
	TransformMeasuresIF	Transforms integer measures to floating point measures (or do the inverse).
