At its core libdmtx is a shared library, allowing C/C++ programs to use its capabilities without restrictions or overhead.
The included utility programs, dmtxread and dmtxwrite, serve as the official interface to libdmtx from the command line, and also provide a good reference for programmers who wish to write their own programs that interact with libdmtx.
Data Matrix barcodes are two-dimensional matrix symbols that hold a dense pattern of data with built-in error correction mechanisms.
