Returns the linear coefficients which define the two dimensional affine transformation.
[Visual Basic .NET] Public Sub QueryLinearCoefficients ( _ ByVal Direction As esriTransformDirection, _ ByRef params As Double _ )
[C#] public void QueryLinearCoefficients ( esriTransformDirection Direction, ref double params );
[C++]
HRESULT QueryLinearCoefficients(
esriTransformDirection Direction,
double* params
);
[C++]
Parameters Direction
Direction is a parameter of type esriTransformDirection params params is a parameter of type double
The QueryLinearCoefficients method allows to get the linear coefficients (a, b, c, d, e, f) for the current Affine Transformation. Please see the AffineTransformation2D coclass for a description of the mathematical model. The array will contain the parameters in alphabetical order.
//Here is the parameters order
double[] dparams=new double[6];
affine2D3.QueryLinearCoefficients(esriTransformDirection.esriTransformForward, ref dparams[0]);
System.Diagnostics.Debug.Print("a=" + dparams[0].ToString());
System.Diagnostics.Debug.Print("b=" + dparams[1].ToString());
System.Diagnostics.Debug.Print("c=" + dparams[2].ToString());
System.Diagnostics.Debug.Print("d=" + dparams[3].ToString());
System.Diagnostics.Debug.Print("e=" + dparams[4].ToString());
System.Diagnostics.Debug.Print("f=" + dparams[5].ToString());
