NAME

       Barcode::DataMatrix::Constants - Constants associated with the Reed-Solomon error
       correction encoding used for data matrices.

DESCRIPTION

       See <https://en.wikipedia.org/wiki/Reed%E2%80%93Solomon_error_correction> for more
       information.

   GFI
       Exponent values used in the multiplication step of the Reed-Solomon encoding algorithm.

   GFL
       Log values used in the multiplication step of the Reed-Solomon encoding algorithm.

   POLY
       Coefficients of the Reed-Solomon coeeficients.  The keys of the "POLY" hash correspond to
       the order of the respective polynomial.
