public class BarcodeDataMatrix extends Barcode2D
A Data Matrix is a two-dimensional bar code consisting of black and white "cells" or dots arranged in either a square or rectangular pattern, also known as a matrix. The information to be encoded can be text or numeric data. Usual data size is from a few bytes up to 1556 bytes. The length of the encoded data depends on the number of cells in the matrix.
