Draw A Rectangle On Any Image in Python
In order to draw a rectangle on any image, you can use the cv2.rectangle() method.
# Import cv2 module
import cv2
# Path to location of image in local storage
location = r'C:\Users\Codesource\Downloads\Python-Logo.jpg'
# Read the image in default mode
image = cv2.imread(location)
# Name of window
window = 'Image'
# Set the coordinates of top left corner of rectangle
top_left = (5, 5)
# Set the coordinates of bottom right corner of rectangle
bottom_right = (220, 220)
# Set the line color to red in BGR
colour = (0, 0, 255)
# Set line thickness to 5px
thickness = 5
# Draw a rectangle with red borders and thickness of 5 px
image = cv2.rectangle(image, top_left, bottom_right, colour, thickness)
# Display the image
cv2.imshow(window, image)
# Show the image until any key is pressed on keyboard
cv2.waitKey(0)
Note: The cv2.rectangle() method functions by drawing a rectangle on any image.
