ZXing library for Java
========================

The ZXing library for Java is a barcode and QR Code scanning library written in Java. It can be used to decode barcode and QR Code data from images and text files, as well as to encode data into barcode and QR Code images. The ZXing library supports several encoding formats such as EAN-13, UPC-A, Data Matrix, and QR Code.

Features
--------

* Supports over 200 encoding formats
* Decodes data from barcode and QR Code images
* Encodes data into barcode and QR Code images
* Supports batch processing of multiple files
* Supports OCR for decoding text files
* Supports custom encoding and decoding rules
* Supports multi-threading for faster processing
* Supports Java SE 6 and later versions

Installation
------------

To install the ZXing library for Java, follow these steps:

1. Download the latest version of the ZXing library from [http://zxing.sourceforge.net/download.html](http://zxing.sourceforge.net/download.html).
2. Extract the downloaded archive to a directory on your computer.
3. Add the ZXing library to your Java project's classpath.
4. Import the ZXing library into your Java project using the following Maven dependency:
```xml
<dependency>
    <groupId>org.zxing</groupId>
    <artifactId>zxing-core</artifactId>
    <version>3.4.0</version>
</dependency>
```
Usage
-----

To use the ZXing library for Java, follow these steps:

1. Import the necessary classes from the ZXing library.
2. Create a new BarcodeReader object and set its parameters as desired.
3. Call the read method on the BarcodeReader object to decode data from an image or text file.
4. Output the decoded data to your program.
5. To encode data into a barcode or QR Code image, create a new BitMatrix object and set its values using the write method of the ZXing library.
6. Output the encoded image to your program.
Examples
--------

Here is an example of how to decode data from a barcode image using the ZXing library for Java:
```java
import org.zxing.*;
import org.zxing.common.BitMatrix;

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.FileInputStream;
import java.io.IOException;

public class ZXingExample {
    public static void main(String[] args) throws IOException {
        // Create a new BarcodeReader object and set its parameters
        BarcodeReader reader = new BarcodeReader();
        reader.setAutoRotateEnabled(true);
        reader.setDisableLuminanceNormalization(false);
        reader.setMaxSizeInches(10, 25);
        reader.setMargins(20, 20, 20, 20);

        // Read data from a barcode image
        BufferedImage image = ImageIO.read(new FileInputStream("barcode_image.jpg"));
        int[] pixels = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();
        int width = image.getWidth();
        int height = image.getHeight();

        BitMatrix bitMatrix = reader.decode(new LINESource(pixels, 0, width, 1, height));

        if (bitMatrix != null) {
            String text = new String(bitMatrix.toArray(), Charset.forName("US-ASCII"));
            System.out.println("Decoded data: " + text);
        } else {
            System.out.println("Failed to decode data.");
        }
    }
}
```
In this example, we first create a new BarcodeReader object and set its parameters as desired. We then read data from a barcode image using the decode method of the ZXing library. If successful, the decoded text is output to the console.
