Wand path_elliptic_arc() function in Python

path_elliptic_arc() is a function specially introduced for paths. path_elliptic_arc() draws an elliptical arc from current point to a particular point we want the arc to drawn to. 
Let's see parameters needed for this function.

Syntax :

wand.drawing.path_elliptic_arc(to, radius, rotation, large_arc, clockwise, relative)

Parameters:

Parameter	Input Type	Description
to	sequence or (numbers.Real, numbers.Real)	pair which represents coordinates to draw to.
radius	collections.abc.sequence or (numbers.Real, numbers.Real)	pair which represents the radii of the ellipse to draw.
rotate	bool	degree to rotate ellipse on x-axis.
large_arc	bool	draw largest available arc.
clockwise	bool	draw arc path clockwise from start to target.
relative	bool	treat given coordinates as relative to current point.

Example : Draw an elliptical curve. 

Python3

from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color

with Drawing() as draw:
    draw.stroke_width = 2
    draw.stroke_color = Color('black')
    draw.fill_color = Color('white')
    draw.path_start()
    # Start middle-left
    draw.path_move(to =(10, 100))
    # draw elliptical curve
    draw.path_elliptic_arc(to =(10, 180),
                           radius = (20, 40),
                           rotation = 270,
                           large_arc = True,
                           clockwise = True,
                           relative = True )
    with Image(width = 200, height = 200, background = Color('lightgreen')) as image:
        draw(image)
        image.save(filename ="pathcurve.png")
