Description Jean-Daniel Dodin 2005-12-17 11:09:01 UTC
Version:           0.8 (using KDE KDE 3.4.2)
Installed from:    SuSE RPMs
OS:                Linux

When one modify an image, the exifs are lost
this was not the case in 0.7.4 - so I switched back to the old version
Comment 1 Jean-Daniel Dodin 2005-12-17 11:31:27 UTC
rpm was found at packman
Comment 2 Tom Albers 2005-12-17 14:23:00 UTC
Please specify step-by-step what you did.
Comment 3 Jean-Daniel Dodin 2005-12-17 15:37:20 UTC
nothing special. view albums, edit them as usual, save the edited image (edited with digikam) and there are no more exifs in the image. See one here:


original one:
Comment 4 Tom Albers 2005-12-17 15:44:14 UTC
if that were the case, nobody would use digiKam. I'll close this bug, unless you can specify how you editted the image...
Comment 5 Jean-Daniel Dodin 2005-12-17 16:51:41 UTC
what do you want me to say? look properties, exif are here. edit the image the exifs are no more. period.

suse 10.0, packman  digikam 0.8
Comment 6 Jean-Daniel Dodin 2005-12-17 17:00:19 UTC
to be more constructive. Is there a way to install the 0.8 without unistallingh the 0.7.4 version? I have the 0.8 rpm on my disk. If I could have the two version I could make more tests

Comment 7 Tom Albers 2005-12-17 17:00:59 UTC
can not reproduce
Comment 8 Jean-Daniel Dodin 2005-12-20 11:52:43 UTC
May I insist??

digikam 0.8 have some feature I whould be able to use :-)

I reinstall it and the bug is here

digikam 0.8.0 (kde 3.4.2 level "b" Suse 10.0)
are installed digikam, the doc and the plugins

from ls -l:
2022954 2005-12-13 10:01 digikam-0.8.0-1.pm.1.i586.rpm
43095126 2005-12-13 10:06 digikam-doc-0.8.0-1.pm.1.noarch.rpm
14614793 2005-12-13 10:03 digikamimageplugins-0.8.0-1.pm.1.i586.rpm

suse rpm found on packman repository, installed with yast (it's usually the best method on suse)

the initial photo (example, content of no interest) with exifs:

open in digikam, edit, correct/colors/automatic level, save
nothing more


I have a french install, so the menu entries may no be exactly as said (of course I can give the french version)

I keep the digikam version for testings and wait for you

Comment 9 caulier.gilles 2005-12-20 12:06:21 UTC
I can't reproduce this problem here (Mandriva 2006). I suspect a broken tarball or installation.

Have you any error messages from the console when you start digikam or showofoto from a command line ?

Have you tested to compile and install yourseft digikam & co on your computer. We are developpers and we working like this, never using packages.

Comment 10 Tom Albers 2005-12-20 12:24:25 UTC
Maybe an old libexif or libkexif?

Have you veryfiedthat libexif and libkexif are installed?

You sould get somthing similar of this:
$ ldd /usr/bin/digikam|grep exif
        libkexif.so.1 => /usr/lib/libkexif.so.1 (0x4b16b000)
        libexif.so.12 => /usr/lib/libexif.so.12 (0x45f5a000)

Comment 12 Jean-Daniel Dodin 2005-12-20 12:37:21 UTC
no error message.

and I _can_ see the exifs in the property dialog box in the files when they are here
is that what you need? (digikam is _not_ in /usr in my install)
jdd@peter-suse:/opt/kde3/lib> ls | grep exif

I may try to compile digikam.
Comment 13 Jean-Daniel Dodin 2005-12-20 17:08:44 UTC
all digikam uninstalled with yast (the suse package manager).

many -dev installed and compile managed.

console launch normal (no file given on command line)

same bug.

Comment 14 Jean-Daniel Dodin 2005-12-20 17:11:10 UTC
I compiled only digicam and the bug seems to come elsewhere. I wil try to compile the plugins.

note: I cam rename a file without loosing the exifs, but I loose them as soon a I do a modif in the editor, even a filter, color change...

Comment 15 Jean-Daniel Dodin 2005-12-20 17:18:36 UTC
I compiled libexif. It seems that the tags names are bold, now, in the view window, but exifs are still lost :-(
go on with plugins...
Comment 16 Jean-Daniel Dodin 2005-12-20 17:51:21 UTC
recompiled plugins, no change.

may be a problem with kde?

I don't know what to do then :-(

This is the problem ! Your HDD is full ? Trying with a different user !

Comment 18 Jean-Daniel Dodin 2005-12-20 20:30:19 UTC
you gave me the hint, I found the problem, but still don't understand why this hits only the exifs.
I noticed that sometimes, quite rarely, I had a "can't write" the file after edit. probably the same origin.

The files I was working on where copyied (by konqueror) from cd's. They kept they readonly attribute (r--r--r--). Restoring the write state closed the bug.

the directory is rwx

I don't understand why I could write the image but not the exifs :-(

this should be advertised somewhere, copying from a backup is a frequent task. I can do this if instructed how :-)

thanks for your help.
Comment 19 Achim Bohnet 2006-02-08 01:31:10 UTC
[ this comment was triggered by http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=349450 ]

Hmm, was this fixed after 0.8.1? There no note when/why
it was set resolved.  I can reproduce it with a write
protected image in 0.8.1:

cp jpeg-with-exif.jpg readonly.jpg
chmod 444 readonly.jpg

start digikam imageeditor with readonly.jpg
RMB -> rotate -> 90 degree
save and exit IE

Now EXIF tab of properties is empty for readonly.jpg :(

Doing the same with original jpeg-with-exif.jpg
and the EXIF tab is still there.

Comment 20 Achim Bohnet 2006-02-08 02:50:56 UTC
I've build 0.8.2-svn from stable trunk and EXIF infos
are still deleted for a readonly picture.   Here the
output digikam writes:

Comment 21 Volker Christian 2006-02-28 20:28:19 UTC
I create a jpeg by use of ufraw from a cr2-raw file, copy the exif information from the cr2 file to the jpeg file with 

   exiftool -overwrite_original -tagsfromfile %f.cr2 -all:all -ext jpg

If i open the file in digikam and try to save it again, i get the output below.
Bad, because all exif-info is lost in the saved file.

I can provide you with example-files also. Just ask!

Please help!

Comment 22 caulier.gilles 2006-03-03 10:59:50 UTC
SVN commit 515268 by cgilles:

digikam from trunk : Metadata support using Exiv2 :

- New image properties sidebar tab named "Metadata" instead old "Exif". This area include :

* Standard Exif tags viewer.
* MarkerNote Exif tags viewer.
* IPTC records viewer.

- New capability to copy metadata in clipboard like text.
- New capability to print metadata.
- Tags name use the "user Friendly" conversion from Exiv2 instead the internal name provided by old Exif viewer based on libkexif.
- Capability to read metadata from CRW files (Canon RAW files)
- New class DMetadata to load/save metadata without loading image data. Actually JPEG, CRW, and PNG files are supported. About PNG (Exif and IPTC raw profiles generated by ImageMagick are supported.

To support new file formats (like NEF, MRW, TIFF, DNG, etc), new image file parsers must be added to Exiv2 library.


- Exiv2 do not support yet gettext for i18n rules. All informations in metadata viewers aren't yet i18n (tags name, tags values, and tags descriptions)
- Any tag names use internal Exiv2 name, not the user friendly text transformations. This point must be fixed in Exiv2 libs.

To 0.9.0, these tools are just metadata readers. Writting capabilities (metadata editors) will added later 0.9.0. The files in B.K.O directly or indirectly relevant of this commits are listed below :

Comment 23 Stuart Prescott 2006-04-01 00:19:59 UTC
Much of this discussion has centred around read-only files, but I see this bug when I import pictures from the camera and let digikam auto-rotate them. When the images are brought in to my "Incoming" folder, portrait photos are automagically rotated and lose their EXIF data but landscape photos still have their EXIF data intact.

Unfortunately, I only just discovered it so my last few hundred portrait photos do not have any EXIF data in them, including the date they were taken :( (i.e. this bug means loss of data making it serious not just mildly annoying)

Good to see some progress noted against this bug, but it is unclear as to whether the svn trunk now has this fixed or not.

(digikam and plugins fom Debian etch 0.8.1-3)
Comment 24 caulier.gilles 2006-04-03 14:05:22 UTC
Tested indeep with current trunk implementation. The problem do not exist in image editor and camera gui.

No test yet done with current implemention of stable branch.  Please give me a feedback.

Comment 25 John Green 2006-04-24 21:42:04 UTC
I also get this after moving to ubuntu dapper package 0.8.1-4ubuntu1. Auto-rotated pictures lose exif after import. This did not happen in the previous version (sorry I do not exactly but would have been with breezy KDE 3.5.2 )
Comment 26 Achim Bohnet 2006-04-27 00:54:05 UTC
Confirmed with 0.8.2-beta1 on Kubuntu/Dapper _when_ the image is write
protected as given in debian bug:



o chmod 444 image-with-exif-info.jpg
o load this image into IE
o Transform -> rotate 90 degree
o save it

==> rotated image is silently overriden, despite the 444 protection.
(silently == no err/info dialog, no output to console).   The exif info
is gone.
