Image to jpeg

Question

From an object java.awt.Image I must obtain an object byte[] type that have to
contain an jpeg imaging type. For doing that I am using the attached code but it
is very slow when it is in execution and it use a lot of energy from the
system. How can i do in order to obtain the same result most quickly?
Thank for you help.
javax.media.Buffer buffergrabber= frameGrabber.grabFrame();
java.awt.Image image= (new javax.media.util.BufferToImage((javax.media.format.VideoFormat)buffergrabber.getFormat()).createImage(buffergrabber));
int pix[]= new int[image.getWidth(null) * image.getHeight(null)];
java.awt.image.PixelGrabber pg= new java.awt.image.PixelGrabber(image, 0, 0, image.getWidth(null), image.getHeight(null), pix, 0, image.getWidth(null));
pg.grabPixels();
java.awt.image.BufferedImage bufferedimage= new java.awt.image.BufferedImage(image.getWidth(null), image.getHeight(null), java.awt.image.BufferedImage.TYPE_INT_RGB);
for (int count= 0; count< image.getHeight(null); count++) {
    for (int count_2= 0; count_2< image.getWidth(null); count_2++) {
        bufferedimage.setRGB(count_2, count, pix[count * image.getWidth(null)+ count_2]);
try {
    java.io.ByteArrayOutputStream bytearrayoutputstream= new java.io.ByteArrayOutputStream();
    com.sun.image.codec.jpeg.JPEGImageEncoder imageencoder= com.sun.image.codec.jpeg.JPEGCodec.createJPEGEncoder(bytearrayoutputstream);
    com.sun.image.codec.jpeg.JPEGEncodeParam encoderparam= imageencoder.getDefaultJPEGEncodeParam(bufferedimage);
    imageencoder.setJPEGEncodeParam(encoderparam);
    encoderparam.setQuality(1.0F, true);
    imageencoder.encode(bufferedimage);
    byte MyJPEGImage[]= bytearrayoutputstream.toByteArray();
catch(java.io.IOException e) {
    System.out.println(e);
}

Best to use the original.
If youv lost it, remove any other objects over the image and size the image to fill the slide, then use export.
