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.

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:

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!

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.

IMPORTANT:

- 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 :

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)

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.

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 )

Confirmed with 0.8.2-beta1 on Kubuntu/Dapper _when_ the image is write
protected as given in debian bug:

 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=349450

Reproduce:

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.
