C# Класс SwfDotNet.IO.Tags.Types.Matrix

Matrix is used to specify two-dimensional coordinate transforms, allowing an object to be scaled, rotated or moved without changing the original definition of how the object is drawn.

A two-dimensional transform is defined using a 3x3 matrix and the new values for a pair of coordinates (x, y) are calculated using a matrix multiplication (see Macromedia specifications).

Different transformations such as scaling, rotation, shearing and translation can be performed using the above matrix multiplication. More complex transformations can be defined by performing successive matrix multiplications in a process known as compositing. This allows a complex transformations to performed on an object.
