Description
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.
[C#]
//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());
