Wand path_curve() function in Python (original) (raw)

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.

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")
