http://bugs.kde.org/show_bug.cgi?id=122264         
           Summary: Exif data fail to show up in recent SVN
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: alfons.hoogervorst gmail com


Version:           SVN (using KDE Devel)
Installed from:    Compiled sources
Compiler:          g++ 3.3.1 compiled from sources
OS:                Linux

Exif data aren't being showed at all (in either simple or full mode). This started since recently this week. I followed the bug #121646 ("Digikam on PPC has problem identifying JPEG and tries to use dcraw with them") discussion, but I don't think it has anything to do with what I see.
I believe the bug was introduced just before the switch to using Exiv 2.0, so it may be either KDE libs related (I'm tracking SVN 3.5 branch), or digikam / extragear/libs related (tracking SVN HEAD).
I'll be digging into this a bit deeper later.

Have you installed the last Exiv2 release (0.9.1) ?

Here all work fine like before to use Exiv2 library. All jpeg files are parsed succefully and Exif metadata are displayed. Have you any error messages with you start digikam from a console ? Can you place any files on the web to download ?

Gilles,
Doesn't matter what images, either shot with a minolta or a canon camera. I did find out that Exiv2 (0.9.1) reads enough data (in the Dimgloader interface), however, the kexifdata doesn't parse the exif data.
I'll try with a newer version of libexif soon.

Another note: in Konqueror, the metafile info (EXIF) data shows up fine. So I think it is in passing the data from Exiv to KExifData.
Digging deeper... :-)

Gilles,
The Exif data shows up empty in both the main interface as well as the image editor. KExifdata inserts empty value strings in its data array / map.

All works fine here. Exif data is showed correctly with digiKam 0.9-svn and
exiv2 v. 0.8

Okay, I recompiled a newer libexif (had to recompile libgphoto2 too), and can't get rid of the problem, so it seems there is some kind of parsing problem.
Please try the image located at http://hoogervorst.dyndns.org/~alfons/wordpress/images/test.jpg; I'll take a further look at the problem tomorrow.

Hello *,

I can see one little related problem, easy to reproduce:

1. Start digikam (latest 0.9.0 svn/KDE3.5.1/i686)
2. First picture in the album is selected but no exif data are visible in the
exif sidebar.
3. Select another picture in the album -> exif data are visible

Regards,
Boguslaw

I think this is a different problem. When selecting a new album, no image is
selected for the right side bar. You can fix this by removing the "emit
signal_noCurrentItem();", line 458, digikam/digikamview.cpp.
But this seems to me more like fixing symptoms - signal/slot connections are a
bit complex there.

ok, i understand exactly what you mean (via Marcel from ML(:=))):

When digiKam start with Exif side enable, the first album automaticly selected by digiKam do not display the first album item Exif info.

If you change current album, Exif info of first current album item are displayed properly.

To resume : something is wrong when digikam is started about indeep signals/slots rules. This is not depending of new Exiv2 depency.

btw, I see this consistently: No exif information at all. I'll be debugging this this week (rather busy right now), so please don't close this bug.
Keep you posted.  :-)

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 :
