#QR Imager Library This is a library to generate .png files from QR codes.

##Dependencies The library depends on the C library https://github.com/fukuchi/libqrencode which you will need to install separately.

##Usage The library exports main functions - createQRCode and byteStringToQR - and their secured/signed versions. The first takes any object that is an instance of ToJSON and writes an image to file, while the second takes a (strict) bytestring and writes it to file.

##Executable

###Installation For building haskell, the best tool is currently http://haskellstack.org. Install it, and then type

stack install --install-ghc

in the appropriate directory, and it will be installed on your path.

###Use

Compiling will generate an executable called QRPipe which reads from stdin and outputs a file as the second argument, e.g.

echo 'My name is:" | QRPipe "nametag.png"
