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:

 

ParameterInput TypeDescription
tosequence or (numbers.Real, numbers.Real)pair which represents coordinates to drawn to.
controlscollections.abc.sequence or (numbers.Real, numbers.Real)coordinate to used to influence curve
smoothboolassume last defined control coordinate
relativebooltreat 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")
