/*
* QR Code generator test worker (C++)
*
* This program reads data and encoding parameters from standard input and writes
* QR Code bitmaps to standard output. The I/O format is one integer per line.
* Run with no command line arguments. The program is intended for automated
* batch testing of end-to-end functionality of this QR Code generator library.
