运行后生成的条形码图片如下：
用手机的扫描软件，识别成功的截图如下：

public class ZxingEAN13DecoderHandler {

Result result = null;
try {

}
LuminanceSource source = new BufferedImageLuminanceSource(image);
BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));

return result.getText();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
/**

public static void main(String[] args) {
String imgPath = "d:/test/twocode/zxing_EAN13.png";
ZxingEAN13DecoderHandler handler = new ZxingEAN13DecoderHandler();
String decodeContent = handler.decode(imgPath);
System.out.println("解码内容如下：");
System.out.println(decodeContent);
System.out.println("Michael ,you have finished zxing EAN-13 decode.");
}
}
运行结果如下：
写道
解码内容如下：
6923450657713
Michael ,you have finished zxing decode.
从测试结果可见：解码出的内容和之前编码的内容是一致。
