This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
QR Imager Library
This is a library to generate
.png files from QR codes.
The library can be used via the exported functions
readQRString, plus their signed counterparts. The first two export to “.png” while the third can be used on any image format
objToImg output JuicyPixels images for your further manipulation.
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: Vanessa" | qrpipe write -v "nametag.png"
To then read the nametag:
qrpipe read "nametag.png"
