# QR Code generator test worker (Python 2, 3)
|
|
#
|
|
# 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.
