IdentityTransform

class ipkiss3.all.IdentityTransform

Transform that leaves an object unchanged.

Parameters:
mirror_center: Coord2, optional

point mirror center, is incorporated in the default translation

mirror_plane_y: float, optional

y ordinate of x axis to mirror around

mirror_plane_x: float, optional

x abscissa of y axis to mirror around

magnification_center: Coord2, optional

magnification center, will be incorporated in the default translation

rotation_center: Coord2, optional

rotation center, will be incorporated in the default translation

absolute_rotation: ( bool, bool_ or int ), optional
absolute_magnification: ( bool, bool_ or int ), optional
v_mirror: optional
magnification: optional
rotation: optional
translation: Coord2, optional

translation, should include any translation required to represent a transformation which is not around the origin
