Beziers provides a variety of classes for constructing, manipulating and drawing Bezier curves and paths. Principally designed for font design software, it allows you to join, split, offset, and perform many other operations on paths.

Here is an example session:

from beziers.point import Point
from beziers.path import BezierPath
from beziers.cubicbezier import CubicBezier
b1 = CubicBezier(
  Point(412.0,500.0), Point(308.0,665.0), Point(163.0,589.0), Point(163.0,504.0)
)
b2 = CubicBezier(
  Point(163.0,504.0), Point(163.0,424.0), Point(364.0,321.0), Point(366.0,216.0)
)
b3 = CubicBezier(
  Point(366.0,216.0), Point(368.0,94.0), Point(260.0,54.0), Point(124.0,54.0)
)
path = BezierPath.fromSegments([b1,b2,b3])
path.closed = False
path.addExtremes()
path.balance()
path.translate(Point(-100.0,-100.0))

import matplotlib.pyplot as plt
fig, ax = plt.subplots()
path.addExtremes()
path.plot(ax)
plt.show()
