IRasterGeometryProc3.GetRasterXFormByIndex Method

Gets the polynomial order and the polynomial coefficients of the indexed transformation.

[Visual Basic .NET]
Public Sub GetRasterXFormByIndex ( _
    ByVal pRaster As IRaster, _
    ByVal band As Integer, _
    ByVal forward As Boolean, _
    ByVal index As Integer, _
    ByRef Order As esriGeoTransTypeEnum, _
    ByRef pVar As Object _
public void GetRasterXFormByIndex (
    IRaster pRaster,
    int band,
    bool forward,
    int index,
    ref esriGeoTransTypeEnum Order,
    ref object pVar
HRESULT GetRasterXFormByIndex(
  IRaster* pRaster,
  long band,
  VARIANT_BOOL forward,
  long index,
  esriGeoTransTypeEnum* Order,
  Variant* pVar
pRaster [in]

pRaster is a parameter of type IRaster* band [in]
band is a parameter of type long forward [in]
forward is a parameter of type bool index [in]
index is a parameter of type long Order [in, out]
Order is a parameter of type esriGeoTransTypeEnum* pVar [in, out]
pVar is a parameter of type VARIANT*

Product Availability

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


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.
