See some examples of how to use the QR Code Tool in Affinity Publisher, which lets you quickly provide all manner of information via a scannable 2D barcode.
I sometimes see QR-Codes that have a random image in the middle and they still work - is that possible with this tool as well? How would I know which pixels can be overlayed to still be a valid QR code? Is there a way to customize the information redundancy amount and maybe a distribution seed, if a different pixel outcome would fit the rest of the image better?
