IProjectiveTransformation2D Interface

Provides access to members that define and manipulate projective transformations.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Members

	Name	Description
	DefineFromControlPoints	Defines the best projective transformation between two sets of points. Can be used to register paper maps on a digitizer.
	DefineFromControlPointsEx	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.
	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).
	TransformMeasuresII	Transforms integer measures to integer measures (or do the inverse).
	TransformPointsFF	Transforms floating point points to floating point points (or do the inverse).
	TransformPointsFI	Transforms floating point points to integer points (or do the inverse).
	TransformPointsIF	Transforms integer points to floating point points (or do the inverse).
	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.
