Qr Code Generator Uses SFML for preview and image creation.
Write text into a file, then run QrCode from the command line using one of the four error levels. Example:
QRgen -f <inputfile>
will create a qr code with error correction level 1, and a preview window will appear.
Alternatively, the message string can be passed via the command line:
QRgen -m "This message is stored in the QR Code" -L 4
Press S to save.
