  double scaleX,
  double scaleY
);

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
