libdmtx is an open-source C library for generating (encoding) Data Matrix symbols, a type of two-dimensional barcode, and reading them from images (decoding). It ships with the command-line tools dmtxread and dmtxwrite, and can be used through wrappers in many languages, including the Python binding pylibdmtx. It is used with Data Matrix in places that need to fit a lot of data into a small area, such as part tracking and industrial labels.
