how to save image as jpg?

[katie]

I have made an application that reads a jpg image, manipulates it like a filter and exports the new data array to a MemoryImageSource and then to an Image.

How can I save this Image or MemoryImageSource to a legal image file such as Bmp, Jpg?
thanks in advance

Code:

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

public class SavingAnImage {

    public static void main(String[] args) throws IOException {
        String path = "images/cougar.jpg";
        BufferedImage src = ImageIO.read(new File(path));
        // Convert Image to BufferedImage if required.
        BufferedImage image = toBufferedImage(src);
        save(image, "jpg");  // png okay, j2se 1.4+
        save(image, "bmp");  // j2se 1.5+
                             // gif okay in j2se 1.6+
    }

    private static void save(BufferedImage image, String ext) {
        String fileName = "savingAnImage";
        File file = new File(fileName + "." + ext);
        try {
            ImageIO.write(image, ext, file);  // ignore returned boolean
        } catch(IOException e) {
            System.out.println("Write error for " + file.getPath() +
                               ": " + e.getMessage());
        }
    }

    private static BufferedImage toBufferedImage(Image src) {
        int w = src.getWidth(null);
        int h = src.getHeight(null);
        int type = BufferedImage.TYPE_INT_RGB;  // other options
        BufferedImage dest = new BufferedImage(w, h, type);
        Graphics2D g2 = dest.createGraphics();
        g2.drawImage(src, 0, 0, null);
        g2.dispose();
        return dest;
    }
}
