Create QRCODE

import qrcode

img = qrcode.make('Binoy Thomas')

print(type(img))   # <class 'qrcode.image.pil.PilImage'>

print(img.size)    # (290, 290)

img.save('QR.png')

Embed QRCode in image

import qrcode

from PIL import Image

img = Image.open('Anupam.jpg')

Unknowingly" is published by Penguin Random House.'''

qr = qrcode.QRCode(box_size=2)

qr.add_data(info)

qr.make()

Qr = qr.make_image()

pos = (img.size[0] - Qr.size[0], img.size[1] - Qr.size[1])

img.paste(Qr, pos)

img.save('Anupam1.png')

Embed image in QRCode

import qrcode

from PIL import Image

face = Image.open('AnupamSmall.jpg').crop((100, 40, 175, 125))

Qr = qrcode.QRCode(error_correction=qrcode.constants.ERROR_CORRECT_H)

Qr.add_data('I am Anupam')

Qr.make()

img = Qr.make_image().convert('RGB')

pos = ((img.size[0] - face.size[0])//2, (img.size[1] - face.size[1])//2)

img.paste(face, pos)

img.save('AnupamSmall.png')

Generate QR Code within GUI

import qrcode

from tkinter import *

qr = qrcode.QRCode(version=1, error_correction=qrcode.ERROR_CORRECT_L,

                   box_size=10, border=4)

win = Tk()

win.geometry("500x500")

S1 = StringVar()

S1.set("https://www.google.com")

ent = Entry(win, width=30, textvariable=S1, font=("Verdana", 16, "bold"))

ent.place(x=20, y=0)

ent.focus()

def generateQRCode():

  qr.add_data(S1)

  qr.make() # generate QR code

  img = qr.make_image()

  img.save("QRCode.png")

  pic = PhotoImage(file="QRCode.png")

  lbl = Label(win, image=pic)

  lbl.place(x=110, y=50)

  lbl.config(image=pic)

  lbl.image=pic

btnGenerate = Button(win, text="Generate", font=("Verdana", 16, "bold"), command=generateQRCode)

btnGenerate.place(x=185, y=400)

win.mainloop()
