ByVal isForward As Boolean, _
ByVal pRaster As IRaster _
) As IPointCollection
public IPointCollection PointsMap2PixelTransform (
IPointCollection pInPoints,

[ByVal pRaster As IRaster] _
)
public void ProjectFast (

IRasterGeometryProc3.PutRasterXForm Method

ByRef pVar As Object _
)
public void PutRasterXForm (
IRaster pRaster,
bool clean,
esriGeoTransTypeEnum Order,
ref object pVar
);
Remarks
The PutRasterXForm method appends a polynomial transformation to a raster. You can also clean the existing transformations on the raster by setting parameter clean to be true. Since calling this method does not automatically update the cell size and extent of the raster like other geometric operations (Shift, Rotate, etc.) do, Rectify or SaveAs will not persist the transformations to a raster dataset directly. Therefore, this method is not recommended for ourside developers.
IRasterGeometryProc3.Rectify Method

Public Sub Rectify ( _
ByVal saveas_name As String, _

ByVal targetControlPoints As IPointCollection, _
ByVal pRaster As IRaster _
)
public void TwoPointsAdjust (
IPointCollection sourceControlPoints,
IPointCollection targetControlPoints,
IRaster pRaster
);

Remarks
Warp method computes a polynomial transformation based on the input links, then applies this transformation to the input raster. The polynomial transformation specified can be first, second, or third order polynomials. Each transformation order requires a minimum number of control links.
