taking images with mss code example

Example 1: python screen recording mss

import time

import cv2
import mss
import numpy


with mss.mss() as sct:
    # Part of the screen to capture
    monitor = {"top": 40, "left": 0, "width": 800, "height": 640}

    while "Screen capturing":
        last_time = time.time()

        # Get raw pixels from the screen, save it to a Numpy array
        img = numpy.array(sct.grab(monitor))

        # Display the picture
        cv2.imshow("OpenCV/Numpy normal", img)

        # Display the picture in grayscale
        # cv2.imshow('OpenCV/Numpy grayscale',
        #            cv2.cvtColor(img, cv2.COLOR_BGRA2GRAY))

        print("fps: {}".format(1 / (time.time() - last_time)))

        # Press "q" to quit
        if cv2.waitKey(25) & 0xFF == ord("q"):
            cv2.destroyAllWindows()
            break

Example 2: python screen recording mss

import mss
import mss.tools


with mss.mss() as sct:
    # The screen part to capture
    monitor = {"top": 160, "left": 160, "width": 160, "height": 135}
    output = "sct-{top}x{left}_{width}x{height}.png".format(**monitor)

    # Grab the data
    sct_img = sct.grab(monitor)

    # Save to the picture file
    mss.tools.to_png(sct_img.rgb, sct_img.size, output=output)
    print(output)
