Wand path_curve() function in Python

Last Updated : 20 Jun, 2021

path_curve() is a function specially introduced for paths. path_curve() draws a cubic bezier curve from the destination point of the Image to a particular point (x, y) with the help of control points.

Syntax :
wand.drawing.path_curve(to, controls, smooth, relative)
Parameters:

Parameter Input Type Description
to sequence or (numbers.Real, numbers.Real) pair which represents coordinates to drawn to.
controls collections.abc.sequence or (numbers.Real, numbers.Real) coordinate to used to influence curve
smooth bool assume last defined control coordinate
relative bool treat given coordinates as relative to current point.

Parameter	Input Type	Description
to	sequence or (numbers.Real, numbers.Real)	pair which represents coordinates to drawn to.
controls	collections.abc.sequence or (numbers.Real, numbers.Real)	coordinate to used to influence curve
smooth	bool	assume last defined control coordinate
relative	bool	treat given coordinates as relative to current point.

Example #1:

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))
    # Curve across top-left to center
    draw.path_curve(to =(80, 0),
                    controls =[(20, -80), (60, -80)],
                    relative = True)
    # Continue curve across bottom-right
    draw.path_curve(to =(80, 0),
                    controls =(60, 80),
                    smooth = True,
                    relative = True)
    draw.path_finish()
    with Image(width = 200, height = 200, background = Color('lightgreen')) as image:
        draw(image)
        image.save(filename ="pathcurve.png")
