In fact, EXIF data is not yet implemented in the TIFF-Exporting
plug-in.
GIMP 2.8 codebase does not even mention
Exif in the plug-in code.
The development version has a
check box to save EXIF data, but no
actually TIff EXIFTAG mentions in the code.

Hi guys,
it is a lot of time that I noted that if I convert a RAW file from my
Canon
camera in TIFF and then I post elaborate it with GIMP, I obtain a file
without
EXIF. No problem whan I convert the RAW file in jpeg.
Can you suggest me some solutions?
Please note for instance this jpeg file obtained from a TIFF file with
GIMP:

Thanks a lot.

Yes you can reassign the control keys. But that doesn't completely solve
the inconvenience. Ypu still have to confirm losing info on exiting
GIMP. There is also a plugin (from Akasha?) which is slightly better
than reassigning, but introduced another problem (I seem to recall).

I think my favorite argument against user preference options is that
"it's too hard and complicated." GiMP is already a masterpiece of
complexity and effectiveness. Writing in an additional user preference
is somehow too much though.
Perhaps it would suffice to turn special warning messages permanently
off, something like a checkbox in the warning dialog: "Don't show this
message again." This is rather common in modern programs and would make
live somewhat easier. I already re-defined CTRL-S to export, but still I
have to click the warning message each time when I close an image.

Well, then I'm lucky this time. My general impression with this mailing

everyone, someone will surely try to make you look like an idiot -- that
makes me cautious.

I haven't found any recent discussions of this issue, so I must ask: Is it
possible to scale/resize a layer or selection about its center? I saw
requests
for this from 2010. This has to be possible. Thanks.

In the gimp 2.9 development preview, hold down control and shift in the
new uniform scaling tool. So it's in the works. This new tool only
really works if your selection or layer fits on the screen, though,
unfortunately, as the controls are glued to the edge of the selection.

Phil,
I doubt that you can do much with these images other than extract the
thumbnail which is obviously quite small.
I used jpeg snoop (http://www.impulseadventure.com/photo/jpeg-snoop.html)
to examine file number 4 and there are markers in the file that should not
be there. Perhaps you can use a hex editor to fix it, I have no idea.
Sorry,
Partha

Hi Partha/all
Ive uploaded/shared 4 pics to dropbox...
0001 is ok
0002 is 75% is ok
0003 is 5% ish ok
0007 is just another 5% ok file
looking though the thumbnails more closely, even some of them seem to
have
corruption, ie pink lines though them, that look to be old ascii symbols,
but cant see that clearly, as they thumbs.
Ill try the Exif extraction tool in a bit, just to try and get something
at least out of the pictures.

Hi All
Apologies to all for not starting a new thread, i have been an avid
reader of the emails for a while now, and read most of what people put
here, so sorry Michael & Jay who pointed that out to me..
ill try and answer all questions about whats what etc.
I believe the original pictures, that were taken in 2011, were taken
directly of the camera via USB cable, these were then stored on my
friends computer, and these were corrupted. I didnt notice it much at
first, as she asked me to look at something different (spamware), but
her screen saver, which must have read the pic folder, showed
pictures,
that looked to be corrupted, i initially thought that these were to
big
for the screen saver to handle, and dismissed them.
She still had the memory card, and the thumbnails, still showed fine
on
camera preview screen, so she thought they were safe. But luckly, she
is
not an avid photographer, and didnt even wipe the card! After that, i
Borrowed the card, and used photorescue (it saved me once so i was
more
than happy to pay for it after my canon 350d corrupted a card that was
not quick enough), and it again found the same pictures corrupted.
So then began my quest for finding information/utilities to
undo/correct
the files.
The Card reader is my own, that i ran the software recovery on, so
with
the fact that since she has bought a new memory card, and it worked
fine, i assume its a faulty card? so i took a copy of what she had.
DSC0001.jpg seems to be fine, this is the first card picture on the
card, i dont know if any were taken before, ie new card or new camera,
but i could find out if needed. DSC0002.jpg, that is ooo 75% ok, but
after that, all the remaining 221 pictures are damaged, all only
showing
about 5%.
I ran imagemagick "mogrify -strip name-of-file.jpg", that ella
suggested, and it gave me a comment unsupported marker type 0x3a
'dsc0002.jpg' @warning/jpeg.c/jpegerrorhandler/313.
I did try loading into Gimp 2.8.2 on debian 7.2 after the imagemagick
command, and it also said this message (i thought i had tried it on
linux but obviously not), OSX 10.6 running gimp 2.8.3 didnt give the
same error message, and im sure windows 7 running gimp 2.8.6 (from
memory) also didnt give the handler error.
From what little research that i have done since, the error is
quite a
complicated one. Something to do with data strips ending in FF D9 in a
hex editor. The 0001 file has 3 of these, the other 2 that i have
tried
only have 1 reference (from searching the file).
Ella's other suggestion for converting from jpg to png, i entered
"convert DSC0002.jpg test.png" and it converted the image, with the
corruption, with no error's reported, also tried dsc0001 and it
converted fine (but the original image was ok).
Im assuming meta data is not transfered to a PNG, ill be honest, i
dont
know much about them, as most of my work is saved back out as JPEG's
etc, apart from when exporting from inkscape, which prefers
PNG's/Tiffs
etc.
Hmm, well, it does sound like file damage rather than just a case of
messed up metadata or a version of jpeg that imagemagick can read and
other
image editors can't. Perhaps someone else can help. I don't know
anything
at all about recovering damaged image files.
If the thumbs are intact, this page:
http://ninedegreesbelow.com/photography/exiftool-commands.html#extract
tells how to use exiftool to extract the thumbnail as a separate image
file. As always, work on a copy of the original.
Good luck!
Elle
