Matrix

class Matrix(pointer: <Error class: unknown class><<Error class: unknown class>>, cleaner: <Error class: unknown class>? = null)

A PangoMatrix specifies a transformation between user-space and device coordinates.

The transformation is given by

x_device = x_user * matrix->xx + y_user * matrix->xy + matrix->x0;
y_device = x_user * matrix->yx + y_user * matrix->yy + matrix->y0;
