enum Goban::ECC::Level

Overview

Error correction level of the QR Code. QR Code symbols include redundant bits based on the selected error correction level, so that even if some part the symbol is not readable, the decoder can recover the loss for up to:

7% for Low
15% for Medium
25% for Quartile
30% for High

Note that choosing a higher error correction level requires more redundant bits, meaning that the resulting QR Code symbol can get larger.
