[Python] Draw Arrow Line

# Python program to explain cv2.arrowedLine() method 
  
# importing cv2 
import cv2 
  
# path 
path = r'C:\Users\Atomix\Desktop\geeksforgeeks\geeks.png'
  
# Reading an image in default mode 
image = cv2.imread(path) 
  
# Window name in which image is displayed 
window_name = 'Image'
  
# Start coordinate, here (0, 0) 
# represents the top left corner of image 
start_point = (0, 0) 
  
# End coordinate
end_point = (200, 200) 
  
# Green color in BGR 
color = (0, 255, 0) 
  
# Line thickness of 9 px 
thickness = 9
  
# Using cv2.arrowedLine() method 
# Draw a diagonal green arrow line
# with thickness of 9 px 
image = cv2.arrowedLine(image, start_point, end_point,
                                     color, thickness) 
  
# Displaying the image 
cv2.imshow(window_name, image)
