For example, we can set QR error correction levels, we can color QR codes, and we can also add logos.
If a logo is added to a QR code, it is automatically resized to an appropriate dimension where the QR can still be read and then snapped to grid so that it is aligned perfectly with the black-and-white squares on the QR image.
