Wand bezier() function in Python

  • Last Updated : 11 May, 2020

The bezier() is another Drawing function in Wand. This method is used to draw a bezier curve. It requires four points to determine a bezier curve. Extreme points define the start and end of the curve while in between two points are used to control the curve.

Syntax: wand.drawing.bezier(points)
Parameters :

ParameterInput TypeDescription
pointslistlist of x, y tuples.

Example 1:






# Import required objects from wand modules
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
  
# generate object for wand.drawing
with Drawing() as draw:
  
    # set stroke color
    draw.stroke_color = Color('black')
  
    # set width for stroke
    draw.stroke_width = 1
  
    # points list to determine curve
    points = [(40, 10), # Start point
              (20, 50), # First control
              (90, 10), # Second control
              (70, 40)] # End point 
  
    # fill white color in arc
    draw.fill_color = Color('white')
  
    # draw bezier curve using bezier function
    draw.bezier(points) 
    with Image(width = 100,
               height = 100,
               background = Color('green')) as img:
  
        # draw shape on image using draw() function
        draw.draw(img)
        img.save(filename ='bezier.png')

Output:

Example #2:

Input Image:




# Import required objects from wand modules
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
  
# generate object for wand.drawing
with Drawing() as draw:
    points = [(20, 100),  # Start point
              (50, 10),  # First control
              (50, 90),  # Second control
              (180, 100)]
  
    # set stroke color
    draw.stroke_color = Color('black')
  
    # set width for stroke
    draw.stroke_width = 1
  
    # fill white color in arc
    draw.fill_color = Color('white')
  
    # draw bezier curve using bezier function
    # From bottom left around to top right
    draw.bezier(points) 
    with Image(filename ="gog.png") as img:
  
        # draw shape on image using draw() function
        draw.draw(img)
        img.save(filename ='bezier2.png')
