How to take screenshots using python?

Python is a widely used general-purpose language. It allows performing a variety of tasks. One of them can be taking a screenshot. It provides a module named pyautogui which can be used to take the screenshot. This module along with NumPy and OpenCV provides the way to manipulate and save the images (screenshot in this case)

pyautogui takes pictures as a PIL(python image library) which supports opening, manipulating, and saving many different image file formats. Then we need to convert the image to NumPy array, so that it can be converted from RGB to BGR because when the image file is read with the OpenCV using imread(), the order of colors should be BGR (blue, green, red).

Modules needed

• Numpy: To install Numpy type the below command in the terminal.

  pip install numpy
  

• pyautogui: To install pyautogui type the below command in the terminal.

  pip install pyautogui
  

• OpenCV: To install OpenCV type the below command in the terminal.

  pip install opencv-python
  

Below is the implementation.

# Python program to take
# screenshots


import numpy as np
import cv2
import pyautogui


# take screenshot using pyautogui
image = pyautogui.screenshot()

# since the pyautogui takes as a
# PIL(pillow) and in RGB we need to
# convert it to numpy array and BGR
# so we can write it to the disk
image = cv2.cvtColor(np.array(image),
                     cv2.COLOR_RGB2BGR)

# writing it to the disk using opencv
cv2.imwrite("image1.png", image)
