How to give transparent border to webcam video in opencv python?

Question

I tried some methods, but nothing works for me. Below is my code

cv2.copyMakeBorder(img,30,30,10,10,cv2.BORDER_CONSTANT,value=[555,555,555,0])

This code shows me border, nothing mean for that last 0. Is there any other way to do this?

Thanks for your attention. I’m looking forward to your reply.

This Works for me :)

import numpy as np
import cv2
from tkinter import *
#import tkinter as tk
from PIL import Image, ImageTk
import sys

window = Tk()  #Makes main window
window.overrideredirect(True)
window.wm_attributes("-topmost", True)
window.geometry("+600+200")
display1 = Label(window)
display1.grid(row=1, column=0, padx=0, pady=0)  #Display 1
cap = cv2.VideoCapture(0)

def show_frame():
    _, frame = cap.read()
    frame = cv2.resize(frame, (400,400))
    #frame = cv2.flip(frame, 1)
    cv2image = cv2.cvtColor(frame, cv2.COLOR_BGR2RGBA)
    img = Image.fromarray(cv2image)
    imgtk = ImageTk.PhotoImage(master = display1, image=img)
    display1.imgtk = imgtk #Shows frame for display 1
    display1.configure(image=imgtk)
    #isQKeyPress = getIsQKeyPress() 
    if False:
        window.destroy()
    window.after(10, show_frame)

show_frame()
window.mainloop()
