IPolynomialXform.DefineFromCoefficients Method

Defines a polynomial XForm from polynomial (order: 0-3) coefficients .

[Visual Basic .NET]
Public Sub DefineFromCoefficients ( _
    ByRef pForwardPolyCoef As Object, _
    ByRef pReversePolyCoef As Object, _
    ByVal Order As Integer _
public void DefineFromCoefficients (
    ref object pForwardPolyCoef,
    ref object pReversePolyCoef,
    ref int Order
HRESULT DefineFromCoefficients(
  Variant* pForwardPolyCoef,
  Variant* pReversePolyCoef,
  long Order
pForwardPolyCoef [in]

pForwardPolyCoef is a parameter of type VARIANT* pReversePolyCoef [in]
pReversePolyCoef is a parameter of type VARIANT* Order [in]
Order is a parameter of type long

Product Availability

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


The polynomial coefficients are a variant array of nx2 elements of double type, where n=3 for the first order, 6 for the second order and 10 for the third order.

To define a PolynomialXform to work with raster dataset, coefficients for both forward case and reverse case must be set.

You can define a PolynomialXform that performs one direction transformation, for transforming other type of data, such as forward transformation, pass Null to reverse coefficient argument.
