CIDataMatrixCodeDescriptor.ECCVersion

Constants indicating the Data Matrix code ECC version.

Declaration

enum ECCVersion

Overview

ECC 000 - 140 symbols offer five levels of error correction using convolutional code error correction. Each successive level or error correction offers more protection for the message data but increases the size of the symbol required to carry a given message. See the ISO/IEC 16022:2006 spec for other modes.

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.
