The bezier() function is an inbuilt function in the Python Wand ImageMagick library which is used to draw the bezier curve from specified points.
Syntax:
bezier(points)Parameters: This function accepts single parameter as mentioned above and defined below:
- points: This parameter is used to specify the value of points. It is of List-type which is used to declare array of points.
Return Value: This function returns the Wand ImageMagick object.
Example 1:
Python3
# Import libraries from the wand from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
with Drawing() as draw: # Set Stroke color the circle to black
draw.stroke_color = Color( 'black' )
# Set Width of the circle to 2
draw.stroke_width = 1
# Set the fill color to 'White (# FFFFFF)'
draw.fill_color = Color( 'white' )
# Set the bezier points as (x, y)
points = [( 40 , 200 ), # Start point
( 120 , 110 ), # First control
( 190 , 180 ), # Second control
( 210 , 360 ), # Third control
( 240 , 240 ), # Fourth control
( 370 , 140 )] # End point
# Set the font style
draw.font = '../Helvetica.ttf'
# Set the font size
draw.font_size = 30
with Image(width = 400 , height = 400 , background = Color( '# 45ff33' )) as pic:
# Set the text and its location
draw.text( int (pic.width / 3 ), int (pic.height / 8 ), 'GFG-BezierCurve' )
# Invoke bezier function with declared points
draw.bezier(points)
# Draw the picture
draw(pic)
# Save the image
pic.save(filename = 'bezier1.jpg' )
