How to get a part of the screen in the clipboard with python

I decided to make this app since windows 11 screen capture app does not work for the moment, after having been one of my moste used tools. So here is the script to use python instead.

This is a working app to grab part of the screen as images, once you click on the yellow button it appears in a window made with tkinter, you have to click on top left and then bottom down of an imaginary rectangle that will be the portion of the screen captured. Once you clicked ont the bottom down part of this imaginary rectangle the portion of the screen will be captured. Now open some app like work and press control + v to see the image that has been copied pasted on the app.

Put the command to open this script in a batch file into a folder that is in the enviromental variables path and you can use is by the command line (search for the post hereRun your python script from the cmd with its name)

# grabscreen.py

import pyscreenshot as ImageGrab
import os
from pynput.mouse import Listener
import sys
import tkinter as tk
from PIL import Image

from io import BytesIO
import win32clipboard


''' Derives from my script grab (use this to show text in a pic and
transform in audio)


'''

def send_to_clipboard(clip_type, data):
    win32clipboard.OpenClipboard()
    win32clipboard.EmptyClipboard()
    win32clipboard.SetClipboardData(clip_type, data)
    win32clipboard.CloseClipboard()

def grab(x, y, w, h):
    im = ImageGrab.grab(bbox=(x, y, w, h))
    im.save('im.png')
    image = Image.open("im.png")
    output = BytesIO()
    image.convert("RGB").save(output, "BMP")
    data = output.getvalue()[14:]
    output.close()
    send_to_clipboard(win32clipboard.CF_DIB, data)


click1 = 0
x1 = 0
y1 = 0
def on_click(x, y, button, pressed):
    global click1, x1, y1, listener
    
    if pressed:
        if click1 == 0:
            x1 = x
            y1 = y
            click1 = 1
        else:
            grab(x1, y1, x, y)
            listener.stop()
            sys.exit()
def start():
    global listener

    # root.destroy()
    print("Click once on top left and once on bottom right")
    # with Listener(on_move=on_move, on_click=on_click, on_scroll=on_scroll) as listener:
    with Listener(on_click=on_click) as listener:
        listener.join()
        # listener.stop()
        # sys.exit()

root = tk.Tk()
root.geometry("400x200")
'''
when you click on this button goes to start
in start there i a listener and when you click it sends you to on_click
in on_click it makes you click twice and then goes to grab
in grab it uses pyscreenshot functions to grab the image and save it
we do not use ocr here, to do it use the grab.py file
'''
but = tk.Button(root, text="GRAB GET IMAGE", command=start, width=20,height=10, bg="gold")
but.pack()

root.mainloop()
