This package improves the display of QR codes provided by qrcode. The Quick
Response (QR) codes provided by package qrcode show white borders on each
square (from little to very prominent, depending on the pdf viewer). This is
because the QR code is printed square by square, not the connected regions of
squares as such, and pdf screen viewers show these undesired borders. This
package overwrites the qrcode printing functions to fill connected regions of
the QR code using TikZ, allowing prettier qrcodes on screen visualization, with
possibility of customization.
