Write image to a file

[prav ford]

Hi,
I have a panel. I select a gif/jpg/* Image file and display the Image on the Panel. Then I have a save button, thru which i have to save the image into a file.

To put it in clear words...I need to read an image from a file and write the image to another file.

Any Ideas.
Thanks,

If you are using j2se 1.4+ you can use the ImageIO class to read and write images. It will read .gif, .jpg and .png and write .jpg and .png images. To save an image:

    ImageIO.write(image, "png", new File("test.png"));

A special download is available from Sun for other image extensions.

yeah that is how it worked for me... sample code below:

public void outputFile() throws Exception{
          //set up file name and dir location
  FileOutputStream fo = new FileOutputStream("graphics/myImg.jpg");
          //buffer it
  BufferedOutputStream bo = new BufferedOutputStream(fo);
          //write the buffered stream as a jpeg
  ImageIO.write(theBufferedImageThatYouHaveLoaded, "jpeg", bo);
  bo.close();
}
