About
-----
This software is for Code-128 barcode detection and decoding. 
Primary is optimized for photos taken by digital camera with
1MPix or so resolution.

There are two variants -- barcode1 and barcode2: 
    -- barcode1 is quick'n'dirty implementation
    -- barcode2 is development version, unsuccessful attempt 
                to recognize smaller images


Requirements
------------
Module libjpeg-dev is required for reading JPEG images (at least 
files jpeglib.h and jpeg.so should be in standard locations).


Installation
------------
Just type "make" and optionally copy compiled barcode1 and barcode2 
executables to $PATH. It should compile cleanly on most Linux and 
*BSD distributions.


Usage
-----
Just execute "./barcode1 image.jpg".
Recognized barcode will be printed to standard output:

    bash$ for i in test-images/* ; do ; \
	      echo $i ; ./barcode1 $i ; done

Algorithm
---------
Algorithms used are described directly in barcode1.c or barcode2.c
source files.
