Overview

Package reedsolomon provides error correction encoding for QR Code 2005.

QR Code 2005 uses a Reed-Solomon error correcting code to detect and correct errors encountered during decoding.

The generated RS codes are systematic, and consist of the input data with error correction bytes appended.

func Encode

func Encode(data *bitset.Bitset, numECBytes int) *bitset.Bitset

Encode data for QR Code 2005 using the appropriate Reed-Solomon code.

numECBytes is the number of error correction bytes to append, and is determined by the target QR Code's version and error correction level.

ISO/IEC 18004 table 9 specifies the numECBytes required. e.g. a 1-L code has numECBytes=7.
