A 3x3 matrix is used for transformations in a 2-D x-y plane. You can multiply affine matrix transformations to form linear transformations, such as rotation and skew (shear) that are followed by translation.
An affine matrix transformation has its final column equal to (0, 0, 1); therefore, you only have to specify the members in the first two columns.
A Windows Presentation Foundation (WPF) Matrix has the following structure:
Methods and properties usually specify the transformation matrix as a vector that has only six members; the members are as follows:
This example shows how to use a to translate (move) the position, stretch, and skew of a Button.
