用java怎么样把图片格式gif转成jpg

[jiangxc2004]

import java.io.File;
import java.io.FileOutputStream;
import java.awt.image.BufferedImage;
import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGImageEncoder;

public class ConvertPic
{

	public void gifToJpg() throws Exception
	{

		File infile = new File("d:/test.gif"); 
		BufferedImage src = javax.imageio.ImageIO.read(infile); 
		int wideth = src.getWidth(null); 
		int height = src.getHeight(null); 
		
		BufferedImage tag = new BufferedImage(wideth , height ,BufferedImage.TYPE_INT_RGB);
		tag.getGraphics().drawImage(src, 0, 0, wideth , height , null);
		FileOutputStream out = new FileOutputStream("d:/test.jpg");
		JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
		encoder.encode(tag);
		out.close();
	}

	public static void main(String[] args)
	{
		try
		{
			new ConvertPic().gifToJpg();
		} catch (Exception e)
		{
			e.printStackTrace();
		}
	}
}

楼上的，很强哦，我看到这个题目一点辙都没有。

这个是输入输出的问题？转存的时候存的格式换一下就OK了

给你来个简单版的

public static void main(String[] args) throws IOException {
		OutputStream out = new FileOutputStream("j:\\aa.jpg");
		ImageIO.write(ImageIO.read(new File("j:\\aa.gif")),"jpg",out);
		out.close();
	}
