IRasterGeometryProc.Warp Method

Warps the input raster based upon the input control points using the transformation type specified.

[Visual Basic .NET]
Public Sub Warp ( _
    ByVal sourceControlPoints As IPointCollection, _
    ByVal targetControlPoints As IPointCollection, _
    ByVal transformType As esriGeoTransTypeEnum, _
    ByVal pRaster As IRaster _
)

[C#]
public void Warp (
    IPointCollection sourceControlPoints,
    IPointCollection targetControlPoints,
    esriGeoTransTypeEnum transformType,
    IRaster pRaster
);

[C++]
HRESULT Warp(
  IPointCollection* sourceControlPoints,
  IPointCollection* targetControlPoints,
  esriGeoTransTypeEnum transformType,
  IRaster* pRaster
);

[C++]

Parameters
sourceControlPoints [in]

  sourceControlPoints is a parameter of type IPointCollection
targetControlPoints [in]

  targetControlPoints is a parameter of type IPointCollection
transformType [in]

  transformType is a parameter of type esriGeoTransTypeEnum
pRaster [in]

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. They are 3, 6, and 10 for order 1,2, and 3, respectively.
