条形码 解析条形码

一个比较好的2d条形码解析条码的工具库
从ZXING 中剥离出来的
测试了一下，还可以，基本上清晰图片都可以识别

import java.awt.Frame;
import java.awt.Graphics2D;
import java.awt.Image;
import java.awt.MediaTracker;
import java.awt.image.BufferedImage;

import com.google.zxing.MonochromeBitmapSource;
import com.google.zxing.MultiFormatReader;
import com.google.zxing.Reader;
import com.google.zxing.ReaderException;
import com.google.zxing.Result;
import com.google.zxing.client.j2se.BufferedImageMonochromeBitmapSource;


public class CodeReader {

	/**
	 * @param args
	 * @throws ReaderException 
	 * @throws InterruptedException 
	 */
	public static void main(String[] args) throws ReaderException, InterruptedException {
		Reader reader = new MultiFormatReader();
		String imgPath = 
			"test.jpg";
		Image image=java.awt.Toolkit.getDefaultToolkit().getImage(imgPath);
		BufferedImage myImage = CodeReader.imageToBufImage(image);
		MonochromeBitmapSource source = new BufferedImageMonochromeBitmapSource(myImage);
		Result result = reader.decode(source);
		System.out.println(result.getText());
	}
	public static BufferedImage imageToBufImage(Image image) throws InterruptedException{
		MediaTracker mt=new MediaTracker(new Frame());  
		mt.addImage(image,0);  
		mt.waitForID(0);  
		BufferedImage bufImage=new BufferedImage(image.getWidth(null),image.getHeight(null),BufferedImage.TYPE_INT_BGR);  
		Graphics2D   g2d=bufImage.createGraphics();  
		g2d.drawImage(image,0,0,null); 
		return bufImage;
	}
