QR Code image generator

Project description

This module uses the Python Imaging Library (PIL) to allow for the generation of QR Codes.

What is a QR Code?

A Quick Response code is a two-dimensional pictographic code used for its fast readability and comparatively large storage capacity. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be made up of any kind of data (e.g., binary, alphanumeric, or Kanji symbols)

Usage

Use the make shortcut function:

import qrcode
img = qrcode.make('Some data here')

Advanced Usage

For more control, use the QRCode class. For example:

import qrcode
qr = qrcode.QRCode(
    version=1,
    error_correction=qrcode.constants.ERROR_CORRECT_L,
    box_size=10,
    border=4,
)
qr.add_data('Some data')
qr.make(fit=True)

img = qr.make_image()

The version parameter is an integer from 1 to 40 that controls the size of the QR Code (the smallest, version 1, is a 21x21 matrix). Set to None and use the fit parameter when making the code to determine this automatically.

The error_correction parameter controls the error correction used for the QR Code. The following four constants are made available on the qrcode package:

ERROR_CORRECT_L

About 7% or less errors can be corrected.

ERROR_CORRECT_M (default)

About 15% or less errors can be corrected.

ERROR_CORRECT_Q

About 25% or less errors can be corrected.

ERROR_CORRECT_H.

About 30% or less errors can be corrected.

The box_size parameter controls how many pixels each “box” of the QR code is.

The border parameter controls how many boxes thick the border should be (the default is 4, which is the minimum according to the specs).
