C# Class Sparrow.Geom.Matrix

The Matrix class describes an affine, 2D transformation Matrix. It provides methods to manipulate the matrix in convenient ways, and can be used to transform points. The matrix has the following form: |a c tx| |b d ty| |0 0 1|

Create ( float a = 1.0f, float b = 0.0f, float c = 0.0f, float d = 1.0f, float tx = 0.0f, float ty = 0.0f ) : Matrix
Identity ( ) : void

Converts the matrix to an Identity matrix
Invert ( ) : void
IsEqual ( Matrix other ) : bool
PrependMatrix ( Matrix matrix ) : void
PrependTranslation ( float dx, float dy ) : void
Rotate ( float angleInRadians ) : void

Applies a rotation on the matrix (angle in radians).
Scale ( float sx, float sy ) : void
