Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Remarks
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.
