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 :
Parameter Input Type Description points list list 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') |
Output:
