QrErrorCorrection

QR Code error-correction level, in ascending order of recoverable damage.

Higher levels devote more of the symbol to redundancy, which means a larger version (and therefore a larger matrix) is needed to hold the same payload.

  • L recovers ~7% of codewords,

  • M ~15%,

  • Q ~25%,

  • H ~30%.
