Summary

Make the rMQR class have the quiet zone.

Background

The rMQR code is surrounded by 2X light modules called quiet zone. This is defined in the ISO/IEC 23941 6.3.10 Quiet zone. However, currently implementation of the rMQR class has no quiet zone. When we generate an image file, QRImage class adds the quiet zone. If clients use the rMQR class directly, they should add the quiet zone in client-side.

Suggestion

Make the rMQR class have the quiet zone.
