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