I have a very important jpeg image corrupted. It have the right size,
and I think most of the data in the image are correct as well. The
preview is available. But gaim shows the following error information:

Corrupt JPEG data: bad Huffman code

EXIF data will be ignored.

Corrupt JPEG data: premature end of data segment

EXIF data will be ignored.

Corrupt JPEG data: premature end of data segment

EXIF data will be ignored.

Does any software do the job to fix this image. Thanks

Cheers,

Jian

Have you tried to open that image in another
program beside Gaim ?

Try XnView (supports Linux, Windows & MacOS)
http://www.xnview.com/
Can XnView open and display the image.

If you use Windows,
You try
IrfanView

FastStone ImageViewer

I've had good luck with freeware PC Inspector File Recovery on deleted or
trashed JPEGs. I think it's published by some German outfit.

Hey CoMa, thanks for your suggestion.

I did try it on different softwares. And even the popular image
recovery tools PixRecovery, it didn't work on it neither.

The reason I want to keep trying is that it seem most the the data in
the jpeg file are ok. since I look on the binary data on the file,
nearly every address have really data there. And furthermore, the
preview are working, but there have white blank edge on both top and
bottom of the preview.

The result of the image on every pics viewer are the same. It look like
an unfinished download image filled with grey on the rest 3/4 space.

Do you think there is any jpeg analyzer that can correct it? Thanks

Hey Bear, Thanks for you help.

The problem for me is little bit diffcult here. Since I copy the image
for someelse's camera, which it still worked ok. However, the image
went wrong on my own HD, and I can't access to the flash card anymore.
So I think the data recovery software would work on my situation. but
thinks :)

if your picture does not contain all the contents of your
original photo (e.g. Windows viewer shows grey colour
in the lower portion instead of the details of your photo,
and you cannot find the missing details in other file),
then most likely that photo is not recoverable.

First look with a hex viewer inside the file to ensure, that the

seems to stem from wrong files, like text.) After that use the
JpegInfo utility from here:

to see what parts of the file contain structural errors. Report
back if you find additional information to that you already posted.
Maybe we find additional ways to help you.

Put the file somewhere on the Net to have people look and analyze

Chances are the file was not fully saved, and this was (90% certainty)
caused by someone disconnecting a storage device without using "safely
remove". This feature is present to allow fast reads and writes, but it
means a file is not fully written unless and until you invoke "safely
remove" before disconnecting a storage device.

It is most likely that the remainder of the image is simply not there, no on
your HDD. This means you will never have the entire image, and no repair
utility can provide missing image data.

It's all speculation. But I don't think what you guessed applies
here. Jian wrote about the image being the correct size and about
errors in the Huffman table *and* the preview. That doesn't sound
like an aborted copy process, but like erroneous data inside the
file header (e.g. the start of the file).

As I said above - it's all speculation...  ;-)  

And besides, repairing a *.jpg having more than one faulty byte
within the encoding tables will be near to impossible.  :-(

Thanks very much for all you guys efforts.  I think Paul's guess is
right. There are something I was missed on last time when I checked it.
There is 2 empty and stuffed block in the middle. One of them is just
about 16kB size. I'd rather give up trying.  I have attach the segment

This commercial software:

same principle as Jpeg-repair.  The 15 day trial is fully functional,
except you can't save the photos. You can get an idea of how Vanmaele
freeware works though.

Sorry but if I remember right, hketech too says that a grey block in
the picture is unrecoverable.

[My hints for Repair-Jpeg usage]

That's okay. Btw.: Did you ever get an answer of the program author?
(You wrote you would try to contact Wim Vanmaele.)

That's nearly always the case. But you'll usually recognize the cause
of such a corruption by looking at the file size or by detecting large
portions of non-data areas inside the file. The first postings of Jian
seemed to describe minor errors. If these errors were inside the header
tables, they could cause big errors with few incorrect bytes.

In his posting from the 4th of December he writes about 2 large errors
in the middle of the file. That implies corruption beyond repair. (But
it still sounds more like unspecific corruption than like an aborted
transmission.)

The JpegInfo data is problematic. JpegInfo unfortunately truncates all
addresses to 16 bit, although the 6 digit display suggests more. That's
why the real size of the 3 images is unknown. (There is a probability
that even the information about 3 embedded images is wrong due to the
corruption.) The inconsistencies of the header data results partly
from the corruption and may also derive from unknown format specifics.
JpegInfo doesn't understand the special features of SPIFF files with
directory structure, for instance. Therefore, it *might* be possible
to extract some good data from the file. But that's definitely not
for sure und most probably not worth the effort...

Still applies.  ;-)
