Note!!!

It's easier to use with python clipboard script!!!

## image to base64

## screencap app: snipaste

import base64
import time
from io import BytesIO
from PIL import Image, ImageGrab
import win32clipboard

def pil():
    pre = 0
    while 1:
        seq = win32clipboard.GetClipboardSequenceNumber()
        if pre == seq:
            time.sleep(0.02)
            continue
        else:
            pre = seq
        # save image
        try:

            img = ImageGrab.grabclipboard()
            if isinstance(img, Image.Image):
                buffer = BytesIO()
                img.save(buffer, 'jpeg')
                b64str = base64.b64encode(buffer.getvalue())
                print(len(b64str))

                b64str = f'data:image/*;base64,{b64str.decode()}'
                # set clipboard
                win32clipboard.OpenClipboard()
                win32clipboard.SetClipboardText(b64str)

                buffer.close()
        except:
