IMatrix

References
public interface IMatrix : IControlObjectSource, IDisposable
Defines a matrix used for transforms in Graphics and Brushes
Remarks: A matrix is defined by six elements that are used to transform a coordinate system. The elements of the matrix are defined as:

| xx yx 0 | | xy yy 0 | | x0 y0 1 |
