qrcode

QR code library in pure Haskell

Basic functionality to create a QRCode.

All modes are supported:

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.

Project Nayuki for https://github.com/nayuki/QR-Code-generator, which is the foundation of this package.

Changed UTF-8 encoding: encoding a code point outside the unicode range will now fail the encoding, previously a replacement character was inserted
Removed a, internal only, partial function
Encoding empty data will result in an empty segment
Encoding an empty segment fails
Added functions to create an (non empty) segment without data
Remove StrictData
