Creating QR Code with Logo

 

import qrcode

from PIL import Image

# Generate QR code for a URL

url = "https://www.clcoding.com"

qr = qrcode.QRCode(version=1, error_correction=qrcode.constants.ERROR_CORRECT_L, box_size=8, border=5)

qr.add_data(url)

qr.make(fit=True)

# Create an image with logo

image = qr.make_image(fill_color="black", back_color="pink")

# Add logo to the QR code

logo = Image.open("clcodinglogo.png")

logo_size = img.size[0] // 4

# Use Image.LANCZOS for resizing with anti-aliasing

logo = logo.resize((logo_size, logo_size), Image.LANCZOS)  

image.paste(logo, ((img.size[0] - logo.size[0]) // 2, (img.size[1] - logo.size[1]) // 2))

# Save the image

image.save("qr_code.png")

Image.open("qr_code.png")

Explantion of the code: 

This code generates a QR code for a given URL (https://www.clcoding.com) using the qrcode library and then adds a logo to the QR code using the PIL (Python Imaging Library) module. Let's break down the code step by step:

Importing libraries:

qrcode: This library is used to generate QR codes.

Image from PIL: This module provides functions to work with images.

Generating the QR code:

The URL "https://www.clcoding.com" is assigned to the variable url.

A QRCode object is created with specific parameters:

version: The version of the QR code (higher versions can store more data).

error_correction: The error correction level of the QR code.

box_size: The size of each box in the QR code.

border: The width of the border around the QR code.

The URL data is added to the QR code using the add_data() method.

The make() method is called to generate the QR code, and fit=True ensures that the size of the QR code fits the data.

Creating an image with the QR code:

The make_image() method is called to create an image representation of the QR code, with specified fill and background colors (fill_color="black", back_color="pink").

The resulting image is stored in the variable image.

Adding a logo to the QR code:

An image of the logo (clcodinglogo.png) is opened using the Image.open() method and stored in the variable logo.

The size of the logo is calculated to be a quarter of the size of the QR code.

The logo is resized using the resize() method with anti-aliasing (Image.LANCZOS filter) to prevent distortion.

The logo is pasted onto the QR code image at the center using the paste() method.

Saving and displaying the final image:

The QR code image with the logo is saved as "qr_code.png" using the save() method.

The saved image is opened and displayed using Image.open().

This code demonstrates how to generate a customized QR code with a logo using Python. Make sure to replace "clcodinglogo.png" with the filename of your logo image.
