Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on.
Description
The methods of the ITransformation interface provide functions that convert arrays of Points or values according to the defined transformation. These methods are more commonly used in other areas of the ArcObjects model, such as Display and SpatialReference. Only the TransformPointsFF and TransformPointsFI are implemented by the AffineTransformation2D coclass.

Remarks
The cPoints parameter is the number of points you wish to transform. inPoints and outPoints are one-dimensional arrays so you must interleave coordinate pairs into the arrays.
The cPoints parameter is the number of points you wish to transform. inPoints and outPoints are one-dimensional arrays so you must interleave coordinate pairs into the arrays. This code is a shift of the points to the east and north.
IAffineTransformation2D transform = new AffineTransformation2D() as IAffineTransformation2D;
//Sets the type of transformation moving the values 10 degrees East and 20 degrees North
transform.Move(10, 20);
//Create two single dimensioned arrays for the inPoints and OutPoints
double[] inPoints = new double[4];
double[] outPoints = new double[4];
//Interleave the Longitude and Latitude value for two points 1.1E 5.2N, 2.3E 6.4N
inPoints[0]=1.1; //Longitude point 1
inPoints[1]=5.2; //Latitude point 1
inPoints[2]=2.3; //Longitude point 2
inPoints[3] = 6.4; //Latitude point 2
