You should write the uploaded image directly to the disk, you reduce its
quality every time your read and write it with ImageIO.

Hi,
Using FileUpload 1.2.1 with Struts the image quality of my JPGs are blurry.
I've had this problem for a couple years, but was hoping that v1.2.1 would
solve the problem.
You can view the before and after images here:

http://www.customerfeedbackllc.com/dev/receipt_after_upload.jpg
Here is the code from my Struts Action class that does the work:
String uploadFilePath = form.getUploadFilePath();
InputStream is = uploadFile.getInputStream(); // uploadFile is a FormFile
BufferedImage bufiIn = ImageIO.read(is);
// bufiIn is stored in a custom object (TransferImage, which extends
Canvas and is Serializable) - here are the essential steps
int[] imgPix = (int[])pix;
int width = bufiIn.getWidth();
int height = bufiIn.getHeight();
BufferedImage bufiOut = new BufferedImage(width, height,
BufferedImage.TYPE_INT_BGR);
image.setRGB(0, 0, width, height, imgPix, 0, width);
// Write the bufi to a tmp file for viewing
ImageIO.write(bufiOut, "jpg", new
File("c:\\tmp\\receipt_after_upload.jpg"));
The receipt_before_upload.jpg comes from a camera phone. Usually, images
coming from scanners are not as blurry.
Can you suggest any way to reduce the blurriness?
Thanks,
