Aztec Code - Encoding

Encoding

Generating an Aztec code The encoding process consists of the steps of:

1. Converting the source message to a string of bits
2. Computing the necessary symbol size and mode message, which determines the Reed-Solomon codeword size
3. Bit-stuffing the message into Reed-Solomon codewords
4. Padding the message to a codeword boundary
5. Appending check codewords
6. Arranging the complete message in a spiral around the core

All conversion between bits strings and other forms is performed according to the big-endian (most significant bit first) convention.
