qrcode

QR code library in pure Haskell

qrcode-core

Basic functionality to create a QRCode.

All modes are supported:

Numeric (digits only)
Alphanumeric (digits, letters and some other chars)
Binary / Text (ISO 8859-1 and UTF-8)
Kanji

There are function to create those specifically and an auto-detect.

The module Codec.QRCode has functions which creates an image out of the input.

The module Codec.QRCode.Intermediate has functions to create segments of a QRCode, join them together and finally create the image.

The core of the resulting image is an Vector of Bools, each element describing a module (“pixel”) where False is white and True is black.
