Remarks

GetRasterXFormByIndex method returns the transformation coefficients and the order of transformation on a specified raster band. The transformation coefficients are returned as a variant, which is an n x 2 array where n varies with the transformation order. First order transformation returns a 3 x 2 array, second order and third order transformations return 6 x 2 and 10 x 2 arrays, respectively.
