Syntax :

wand.drawing.line(start, end)

Parameters :

Parameter	Input Type	Description
start	sequence or (numbers.Integral, numbers.Integral)	pair which represents starting x and y of the arc.
end	sequence or (numbers.Integral, numbers.Integral)	pair which represents ending x and y of the arc.

Example #1:

Python3

# 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('green')
    # set width for stroke
    draw.stroke_width = 1
    draw.line(( 50, 50),  # Stating point
             ( 150, 150))  # Ending point
    with Image(width = 200,
               height = 200,
               background = Color('white')) as img:
        # draw shape on image using draw() function
        draw.draw(img)
        img.save(filename ='line.png')

Output :

Example #2: Draw a line on a pre-existing image.
Source Image:

Python3

# 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('white')

    # set width for stroke
    draw.stroke_width = 1
    with Image(filename = "gog.png") as img:
        draw.line((( img.height)/2, 0),  # Stating point
                   ( 0, (img.width)/2))  # Ending point

        # draw shape on image using draw() function
        draw.draw(img)
        img.save(filename ='line2.png')
