QR code library in pure Haskell
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)
There are function to create those specifically and an auto-detect.
Codec.QRCode has functions which creates an image out of the input.
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
Bools, each element
describing a module ("pixel") where
False is white and
True is black.
This package adds a function to convert the QRCode into a JuicyPixels image. And some to create a data url containing the QRCode as a PNG.
