Python OpenCV | cv2.line() method

OpenCV-Python is a library of Python bindings designed to solve computer vision problems.cv2.line() method is used to draw a line on any image.

Syntax: cv2.line(image, start_point, end_point, color, thickness)

Parameters:

image: It is the image on which line is to be drawn.

start_point: It is the starting coordinates of line. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).

end_point: It is the ending coordinates of line. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).

color: It is the color of line to be drawn. For BGR, we pass a tuple. eg: (255, 0, 0) for blue color.

thickness: It is the thickness of the line in px.

Return Value: It returns an image.

# Python program to explain cv2.line() method

# importing cv2

import cv2

# path

path = r'lab3.jpg'

# Reading an image in grayscale mode

image = cv2.imread(path, 0)

# Window name in which image is displayed

window_name = 'Image'

# Start coordinate, here (0, 0)

# represents the top right corner of image

start_point = (0, 0)

# End coordinate, here (696, 548)

# represents the bottom left corner of image

end_point = (696, 548)

# Black color in BGR

color = (0, 0, 0)

# Line thickness of 5 px

thickness = 5

# Using cv2.line() method

# Draw a diagonal black line with thickness of 5 px

image = cv2.line(image, start_point, end_point, color, thickness)

# Displaying the image

cv2.imshow(window_name, image)

Python OpenCV | cv2.rectangle() method

OpenCV-Python is a library of Python bindings designed to solve computer vision problems. cv2.rectangle() method is used to draw a rectangle on any image.

Syntax: cv2.rectangle(image, start_point, end_point, color, thickness)

Parameters:

image: It is the image on which rectangle is to be drawn.

start_point: It is the starting coordinates of rectangle. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).

end_point: It is the ending coordinates of rectangle. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).

color: It is the color of border line of rectangle to be drawn. For BGR, we pass a tuple. eg: (255, 0, 0) for blue color.

thickness: It is the thickness of the rectangle border line in px. Thickness of -1 px will fill the rectangle shape by the specified color.

Return Value: It returns an image.

Code

# Python program to explain cv2.line() method

# importing cv2

import cv2

# path

path = r'lab3.jpg'

# Reading an image in grayscale mode

image = cv2.imread(path)

# Window name in which image is displayed

window_name = 'Image'

# Start coordinate, here (5, 5)

# represents the top left corner of rectangle

start_point = (5, 5)

# Ending coordinate, here (220, 220)

# represents the bottom right corner of rectangle

end_point = (220, 220)

# Blue color in BGR

color = (255, 0, 0)

# Line thickness of 10 px

thickness = 10

# Using cv2.rectangle() method

# Draw a rectangle with blue line borders of thickness of 2 px

image = cv2.rectangle(image, start_point, end_point, color, thickness)

# Displaying the image

cv2.imshow(window_name, image)

Python OpenCV | cv2.circle() method

OpenCV-Python is a library of Python bindings designed to solve computer vision problems. cv2.circle() method is used to draw a circle on any image.

Syntax: cv2.circle(image, center_coordinates, radius, color, thickness)

Parameters:

image: It is the image on which circle is to be drawn.

center_coordinates: It is the center coordinates of circle. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).

radius: It is the radius of circle.

color: It is the color of border line of circle to be drawn. For BGR, we pass a tuple. eg: (255, 0, 0) for blue color.

thickness: It is the thickness of the circle border line in px. Thickness of -1 px will fill the circle shape by the specified color.

Return Value: It returns an image.

Code

# Python program to explain cv2.line() method

# importing cv2

import cv2

# path

path = r'lab3.jpg'

# Reading an image in grayscale mode

image = cv2.imread(path)

# Window name in which image is displayed

window_name = 'Image'

# Center coordinates

center_coordinates = (200, 200)

# Radius of circle

radius = 100

# Blue color in BGR

color = (0, 0, 255)

# Line thickness of 2 px

thickness = 2

# Using cv2.circle() method

# Draw a circle with blue line borders of thickness of 2 px

image = cv2.circle(image, center_coordinates, radius, color, thickness)

# Displaying the image

cv2.imshow(window_name, image)
