Database problem

Carl McGrath — 2012-05-26T00:51:13

I am seeing the following error when starting Digikam from CLI:

     QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is 
still in use, all queries will cease to work

Searching about, the consensus seems to be to rebuild a new database.
Any other ideas out there?

Feature request.

Hello, and thanks very much for the DigiKam/ShowFoto application. I use 
it a lot, and occasionally use GIMP. This is an independent 
outside-origin email for the developers; I'm not a member of the DigiKam 
users homepage and have not mentioned this matter inside the relevant 
forums.

Just a quick request for a couple of additional features:

Since many computer users have a dual monitor setup, it would be nice to 
have another Composition Guide within the Aspect Ratio Crop function. 
When I edit a given image for use as a dual-screen desktop picture, it's 
visually relevant to crop and divide the image, such that the physical 
split between two monitors isn't too distracting. To aid in such 
"crop-composition", a simple horizontal and vertical cross formation 
would be very useful into the Geometric form set of choices. The 
diagonals, triangles, and divisions-into-thirds are of no help, when 
dividing an image into exactly half. This would save some time when 
adjusting the final desktop image to look th

Hello David,

you can configure this.

In "Settings"
  -> "Configure DigiKam..."
    -> "Metadata"
      -> "Behaviour"
        -> "Common Metadata Actions"
you can select
 "[x] Save image rating in metadata embedded in files"

This will write any further image ratings in your digiKam
database and the jpg file.

For all old jpgs:
  1. Start a search to get them all
  2. select all
  3. "Image" -> "Write Metadata to image"

To make sure, everything worked, I looked with a hex editor
(e.g. "Okteta" or just "xxd") at the jpg files. ;)

Regards,
Peter

Hello Jean-François,

thank you for your answer. Everything is clearer for me now. For the videos I will also use companion images. Like you said, it's not the best solution, but for the moment It'll be ok. So now I can start to also tag my video.

Best regards,

Cédric

P.S: if somebody else has something to add, don't hesitate!

Where to find my digikam configuration

Geert Jan klinkhamer — 2012-05-20T08:21:44

Hallo,

I am since 4 years a user for digikam in gnome and very happy with the
functionality.
I am planning for a new computer on which I want to install the same
software with the same configuration. I have a way to transfer my software
repository.
But where to find my digikam configuration files, so I don't have to
manually input my tag-structure.
I found some but I don't know if it is all

Please your help.

Re: merge two digikam DBs

Peter Albrecht — 2012-05-20T18:17:35

Hello David,

if your database contains only jpgs (no raws or videos) you
could do this:

 1. write all metadata into those jpgs
 2. start a new database
 3. include both root folders, containing your databases

DigiKam should find and read metadata (tags, comments and
ratings) from your jpg files.
This way you could also include one database in another
existing one. You don't have to start with a new database.

This attempt fails, if you have:
 - raws with metadata (tags, ratings, ...)
 - videos with metadata (tags, ratings, ...)
 - metadata which can't be written to jpg files

Peter

Hi all,

I would like to merge two digikam DBs (v2.5.0). I found some posts on
the mailing list but couldn't find the description in the docs. The docs
linked from digikam.org to docs.kde.org do not exist btw.
Could anybody give me a hint how to do the merge?

do not know what linear DNG specificaly is, but you can use DNG converter
tool (not Digikam) to convert your camera native RAW into DNG.

I use it to convert Nikon NRF files, since RAW processing tools don't like
NRF format too much

Elliot Newman — 2012-05-18T15:54:57

Hello,

I am trying to find out if DigiKam allows you to read in a raw file (like canon CR2) and write out a linear DNG just like Adobe DNG Converter. I know LibRaw has support for this... more info on linear DNG:

Hello Cédric,
some comments as I see two different issues in your post.

Metadata world is a swampy and misty landscape. Some standards exist but
they mostly define data formats and labels, and are more unfocused on
data semantics and where to put what. A software development team may
have its own interpretation and another team may disagree and do

(Digikam itself does some interpretation in metadata handling, and not
everybody agrees.)

Also, software often needs some information not featured in standards

Compatibility is then broken.

Tags and metadata for photo and video

Cédric Macquat — 2012-05-17T11:03:50

Hello,

I want to manage my photo collection and video collection with digikam.
With digikam I tagged my photos and I want to begin with the video. My
problem is the following: If I want to use another software to manage my
photos and video in the future (perhaps one time another one will fit
better to my needs, but for the moment digikam is perfect :-D) how can I
make sure I don't have to retag everything ? When I will have much more
photos and videos it won't be possible to do the work again. 
For the moment I did the following. At first I had photos in jpg format.
I had written the tags in the jpg files. But now I have a mixt of photo
in jpg and raw format. I can't write the tags in the metadata of the raw
format. It would be possible (I saw it's experimental for the moment) to
write in the raw files, but it's not advised. So I discovered the xmp
sidecar and I created for every tagged photos a .xmp file. 
But now I will tag my videos and with digikam it's not possible to

In reference to "and perhaps a bad idea for original
out-of-camera jpgs as well":
Writing metadata to JPGs works very well for me, for several
years now.

The only drawback I can think of is the mentioned "changing
the original".

But I decided for me, to _not keep_ the original
out-of-camera-jpgs. So I can live with this "issue". But
this is a decision everyone has to make him-/herself.

HDR and 2.6.0 RC

POTTIER Michel — 2012-05-16T15:14:25

Hello all,
 I am trying to make HDR with two jpegs. In the tools menus I choose "fusionner les images prises en fourchettes". 
A box appears with the names of the binaries (align_image_stack 2011.4.0 and enfuse 4.0). Then "next", another box  with the names of the two images. 
Then "next" I arrive on  "aligner les images". Next "cette operation peut prendre un peu de temps" and "Le prétraitement a échoué (Preprocessing failed)" . 
By clicking on "details" open another empty box.
Running digikam in a terminal, i obtain the following output:

Re: BUG? move to album / overwrite destinationproblem

Remco Viëtor — 2012-05-16T09:10:54

...

For me, there are two reasons to avoid writing to RAW files:
- They are the original, irreplacable data that I like to keep in its original 
state.  (I have backups, but still...)
- There is no such thing as _a_ raw format: every camera maker has his own 
formats (yes, plural :( ) And those formats are poorly specified, especially 
wrt to the 'makerdata' EXIF section, so it's very easy to corrupt something 
when writing to such a file. The situation is getting better through a lot of 
hard work from volunteers (not me, I hasten to add), but given the sheer 
number of raw formats in existence, there will probably always be formats that 
are not understood.

Also, RAW files in general only have EXIF data, part of which can be pure 
binary data, and possibly encrypted (makernote..)

Remco

Hello,

I happened, at some occasions, to use hard links in a (maybe) similar way
as John does (have a folder with a bunch of images and some other folders
with selected images subsets).

I confirm Digikam doesn't recognize/handle links. When pathnames are 
different, the images are seen as different even if it's the same file,
and database entries are different too.

What I used to do for final cleanup after tagging/rating/indexing was :
  - Run the « Find duplicates » function on the root folder (nearest root
    above linked images),
    As linked files are the same, obviously the two images are found to
    be duplicates,
  - In the duplicates search results view, set the display filter to
    show only unrated/untagged images,
  - Select all, Ctrl-A, then delete.
  - After that, move, reorganise the remainding (rated/tagged) images.

(This worked well. I must say I no longer work like that. Now I tend to
copy SD-card content into a new folder, then browse the images and tag
those I want to keep, the
