image to jpg

I managed to do this with ImageIO, example taken from:

http://www.geocities.com/marcoschmid...creenshot.html

watch out for the javascript errors, but good site with loads of image and
java stuff...

This was the code I used.

// temp output file bit
public void outputFile() throws Exception{
//start of the output stuff

FileOutputStream fo = new FileOutputStream("myImg.jpg");//name of image

BufferedOutputStream bo = new BufferedOutputStream(fo);//set to buffered
stream

//destination here is the name of the raster reference. referencing a
bufferedImage
ImageIO.write(destination, "jpeg", bo);//write the file out using ImageIO
to the HD

bo.close();
//end of the output stuff
}
// EOF temp outupt file bit

hope this helps

cheers
Martin

I am saving a BufferedImage as a JPEG file under Windows XP.
I am using the JAI JPEGImageEncoder class.
The JPEG is saved as CMYK but I need RGB.
I cannot figure out how to get RGB. Any help?


Where is the BufferedImage coming from? If you're creating the object
yourself, try using INT_RGB imageType instead of the default ARGB.

image = new BufferedImage(x, y, BufferedImage.TYPE_INT_RGB);

It might also be worth trying this:

JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(os);
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(image);
encoder.encode(img, param);
