IPolynomialXform.ApplyScale Method

Applies a scale to the polynomial.

[Visual Basic .NET]
Public Sub ApplyScale ( _
    ByVal direction As esriTransformDirection, _
    ByVal scaleX As Double, _
    ByVal scaleY As Double _
)
[C#]
public void ApplyScale (
    esriTransformDirection direction,
    double scaleX,
    double scaleY
);
[C++]
HRESULT ApplyScale(
  esriTransformDirection direction,
  double scaleX,
  double scaleY
);
[C++]

Parameters

direction [in]

  direction is a parameter of type esriTransformDirection

scaleX [in]   scaleX is a parameter of type double scaleY [in]   scaleY is a parameter of type double

Product Availability

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

Remarks

ApplyScale method appends an xform to the existing PolynomialXform. To define an scale transformation to work with raster data using this method, you must define both forward and inverse transformations.

For example, to define a scale transformation, you need to call

 

pPolynomialXform.ApplyScale TransformationForward, 10

pPolynomialXform.ApplyScale TransformationReverse, 1/10
