how to render an image in browser from server to client

i got the answer with scaling of image if any body care u can check it

<%

String filepath=request.getParameter("file");

File theImageFile = new File (filepath);

String name=filepath.substring(filepath.lastIndexOf("\\")+1);

if(name!="Thumbs.db")

{

//outputImage(theImageFile, "jpeg", response);

//public static void outputImage(File theImageFile, String type, HttpServletResponse response) throws IOException

// {

response.setContentType("image/jpeg");

FileInputStream fin = new FileInputStream(theImageFile);

OutputStream os = response.getOutputStream();

byte[] buf = new byte[4026];

int count1 = 0;

while(true) {

int n = fin.read(buf);

if(n == -1) {

break;

}

count1 = count1 + n;

int thumbWidth = Integer.parseInt("200");

int thumbHeight = Integer.parseInt("200");

Image img = Toolkit.getDefaultToolkit().getImage(filepath);

// Image image = img.getScaledInstance(thumbWidth, thumbHeight ,Image.SCALE_FAST);

Image image = img.getScaledInstance(thumbWidth, thumbHeight ,Image.SCALE_SMOOTH);

MediaTracker mediaTracker = new MediaTracker(new Container());

mediaTracker.addImage(image, 0);

mediaTracker.waitForID(0);

// determine thumbnail size from WIDTH and HEIGHT

double thumbRatio = (double)thumbWidth / (double)thumbHeight;

int imageWidth = image.getWidth(null);

int imageHeight = image.getHeight(null);

double imageRatio = (double)imageWidth / (double)imageHeight;

if (thumbRatio < imageRatio) {

thumbHeight = (int)(thumbWidth / imageRatio);

} else {

thumbWidth = (int)(thumbHeight * imageRatio);

}

// draw original image to thumbnail image object and

// scale it to the new size on-the-fly

BufferedImage thumbImage = new BufferedImage(thumbWidth,

thumbHeight, BufferedImage.TYPE_INT_RGB);

Graphics2D graphics2D = thumbImage.createGraphics();

graphics2D.setRenderingHint(RenderingHints.KEY_INTERPOLATION,

RenderingHints.VALUE_INTERPOLATION_BILINEAR);

graphics2D.drawImage(image, 0,0, thumbWidth, thumbHeight, null);

// save thumbnail image to OUTFILE

BufferedOutputStream op = new BufferedOutputStream(new

FileOutputStream(filepath));

JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(op);

JPEGEncodeParam param = encoder.

getDefaultJPEGEncodeParam(thumbImage);

int quality = Integer.parseInt("50");

quality = Math.max(0, Math.min(quality, 100));

param.setQuality((float)quality / 100.0f, false);

encoder.setJPEGEncodeParam(param);

encoder.encode(thumbImage);

os.write(buf,0,n);

}

os.flush();

os.close();

fin.close();

}
