Graphics Programming with GDI+

10.3. The Matrix Class and Transformation

Matrices play a vital role in the transformation process. A matrix is a multidimensional array of values in which each item in the array represents one value of the transformation operation, as we will see in the examples later in this chapter.

In GDI+, the Matrix class represents a 3×2 matrix that contains x, y, and w values in the first, second, and third columns, respectively.

Note

Before using the Matrix class in your applications, you need to add a reference to the System.Drawing.Drawing2D namespace.

We can create a Matrix object by using its overloaded constructors, which take an array of points (hold the matrix items) as arguments. The following code snippet creates three Matrix objects from ...
