only.Expand description
Constants indicating the Data Matrix code ECC version.
ECC 000 - 140 symbols offer five levels of error correction using convolutional code error correction. Each successive level of error correction offers more protection for the message data and increases the size of the symbol required to carry a specific message. ECC 000 symbols offer no data protection. The other modes are described in ISO/IEC 16022:2006 and enumerated in this list only for completeness.
ECC 200 symbols utilize Reed-Solomon error correction. The error correction capacity for any given Data Matrix symbol is fixed by the size (in rows and columns) of the symbol. See Table 7 of ISO/IEC 16022:2006(E) for more details.
Indicates error correction using convolutional code error correction with no data protection.
Indicates 1/4 of the symbol is dedicated to convolutional code error correction.
Indicates 1/3 of the symbol is dedicated to convolutional code error correction.
Indicates 1/2 of the symbol is dedicated to convolutional code error correction.
Indicates 3/4 of the symbol is dedicated to convolutional code error correction.
Indicates error correction using Reed-Solomon error correction. Data protection overhead varies based on symbol size.
