Quirc bindings for Ruby

Quirc is a small C library for extracting and decode QR codes from images. This project is a Ruby binding for that library with the library embedded.

Example

You have to supply a ChunkyPNG object or a binary string of the grayscale image with width and height.

require 'chunky_png'
require 'quirc'

img = ChunkyPNG::Image.from_file('path_to_image.png')
res = Quirc.decode(img).first
puts res.payload
require 'base64'
require 'zlib'
require 'quirc'

encoded = <<~EOD

img = Zlib::Inflate.inflate(Base64.decode64(encoded))
res = Quirc.decode(img, 120, 120).first
puts res.payload
