IAffineTransformation2D Interface

Provides access to members that define and manipulate affine transformations. Note: the IAffineTransformation2D interface has been superseded byIAffineTransformation2D3. Please consider using the more recent version.

Description

The IAffineTransformation2D interface defines the function of a transformation, that is, how the coordinates of a Geometry are altered by the transformation. Use the DefineFromControlPoints, DefineFromEnvelopes, DefineFromEnvelopesEx, DefineReflection, Move, MoveVector, Project, Rotate, or Scale methods to define transformation functions for the AffineTransformation2D.

Members

	All Properties Methods Inherited Non-inherited	Description
	DefineFromControlPoints	Defines the best affine transformation between two sets of points. Can be used to register paper maps on a digitizer.
	DefineFromEnvelopes	Defines a transformation that maps a point relative to one envelope to a similar position relative to another envelope.
	DefineFromEnvelopesEx	Defines a transformation that maps a point relative to one envelope to a similar position relative to another envelope.
	DefineReflection	Defines a transformation that can perform a reflection about the line l.
	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.
	IsReflective	Indicates if the transformation contains a reflection (determinant is negative).
	Move	Incorporates a translation factor into the transformation.
	MoveOrigin	The origin of accumulated transformations used when projecting an affine transformation to a different spatial reference system.
	MoveVector	Performs an X and Y translation defined by a 2D vector.
	PostMultiply	Post-multiplies the transformation by another transformation.
	PreMultiply	Pre-multiplies the transformation by another 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.
	Reset	Resets the tranformation.
	Rotate	Incorporates a rotation (in radians) into the transformation.
	Rotation	The rotation angle. Will not be able if different x/y scale factors have been incorporated into the transformation.
	Scale	Incorporates scale factors into the 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).
	XScale	The scale along the X axis.
	XTranslation	The translation along the X axis.
	YScale	The scale along the Y axis.
	YTranslation	The translation along the Y axis.
