Detailed Description

Defines a 2D transformation matrix.

Contains rotation and translation part and a scale factor. A rotation part (2 x 2 matrix) must not contain a scale factor or inversion, i.e. its matrix determinant must be equal to 1.

Individual matrix elements can retrieved using the Data() method.

Constructor & Destructor Documentation

Transformation2d()

cadex.Geom.Transformation2d.Transformation2d ( )

inline

Constructor.

Creates an identity matrix.

Member Function Documentation

Invert()

void cadex.Geom.Transformation2d.Invert ( )

inline

Inverts the matrix.

Makes this matrix an inverse, i.e. A * A^(-1) = I.

SetScaleFactor()

void cadex.Geom.Transformation2d.SetScaleFactor ( double theScale )

inline

Sets a scale factor.
