> DataMatrix libraries for industrial marking: **dmr** reads GS1 DataMatrix codes (including Russian "Chestny ZNAK" marking) from camera frames, **dmgen** generates DataMatrix ECC 200 symbols as PNG/JPEG. C++20 API, C ABI, Python packages (`pip install libscanner-dmr`, `pip install libscanner-dmgen`) and a command-line tool, for Windows and Linux. Each library runs a trial period (one month from the first run on a machine, no network needed); after that a license from https://libscanner.com is required.

Products:
- **DataMatrix Reader** (`datamatrix-gs1`): Reads GS1 DataMatrix codes from industrial camera frames — for conveyor lines marked under Chestny ZNAK, the Russian product marking system. Source and releases: https://github.com/libscanner/datamatrix-reader
- **DataMatrix Generator** (`datamatrix-generator`): Generates DataMatrix ECC 200 symbols per ISO/IEC 16022 (GOST R ISO/IEC 16022) with GS1 and Chestny ZNAK profile validation — PNG and JPEG for marking print. Source and releases: https://github.com/libscanner/datamatrix-generator
