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: optional

absolute_magnification: optional

v_mirror: optional

magnification: optional

rotation: optional

translation: optional

Examples

import ipkiss3.all as i3
import pylab as plt

sh = i3.Shape([(5.0, 2.0), (12.0, 3.0), (17.0, 9.0), (7.0, 6.0)])

sh2 = sh.transform_copy(i3.VMirror(mirror_plane_y=2.0))

plt.plot(sh.x_coords(), sh.y_coords(), 'bo-')
plt.plot(sh2.x_coords(), sh2.y_coords(), 'ro-')
plt.axhline(y=2.0, linestyle='dashed')
plt.show()
