Wand point() function in Python

Last Updated : 01 Jun, 2021

point() is another drawing function and simplest of all. point() function basically draw a point on a particular point on an image. It simply takes two x, y arguments for the point coordinate.

Syntax :
wand.drawing.point(x, y)
Parameters:

Parameter Input Type Description
x numbers.Real x coordinate of point
y numbers.Real y coordinate of point

Example #1:

Python3

# Import different modules of wand
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color

# object for Drawing
with Drawing() as draw:
    x = 100
    y = 100
    # draw point at (100, 100) using point() function
    draw.point(x, y)

    with Image(width = 200, height = 200, 
               background = Color('lightgreen')) as image:

        draw(image)
        image.save(filename ="point.png")

Output:

Example #2:

Python3

# Import different modules of wand
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
import math

with Drawing() as draw:
    for x in xrange(0, 200):
        y = math.tan(x) * 4
        # draw points at different locations using point() function
        draw.point(x, y + 50)
    with Image(width = 200, height = 200, background = Color('lightgreen')) as image:
        draw(image)
        image.save(filename = "points.png")

Output:
