         The Decode Library for Linux v.20.10.1
         BS_18   g++ 7.5.0
         -------------------------------------------------------
1. Following files are supplied within SDK:

 1.1 Library for application development

  libQRCode.so	 - library with decoding functions
  
 1.2 Source codes of demo program that applies the library

  QRPro_Types.h   - header file that describes interface of library
  Demo_Opn_Rtl.cpp - source codes of sample application that uses our library
  LoadBMP.c, LoadBMP.h - the functions for loading "BMP" files
  
  twodtg_license.h - license managment

 1.3 Executable files
  demo.out - demo program (applicatiom) that was built from Demo_Opn_Rtl.cpp
		    source code.
  TwoDtgLicense - GUI application for managed a license.

 1.4 Short SDK description
  readme.txt	 - this file.


2. Unpack all files into same directory. 
   Copy libQRCode.so to /usr/lib. 
   Set right "executable" for file "demo.out" and "TwoDtgLicense"
   Run "demo.out".
   
   For activation license use a TwoDtgLicense.
   Attention: 
   For the initial initialization of the license, the application must be started with root access!
 	
3. Source .cpp and .h files show how the library functions should be called.
Build Limux demo application by command:

  g++ Demo_Opn_Rtl.cpp -L./ -lQRCode -lm -pthread -ldl -lz -o mydemo.out

4. If compilation generates instant executable program "mydemo.out" 
you can run the program in the same way as described in 2.
