some questions

Johannes Kapune
Dear all,

thanks for improving Digikam.

Now I use DigiKam 4.10.0 on openSUSE 13.2

Maybe my questions are related to my (wrong) work flow?

First my hardware configuration:

My pictures are placed on a NFS-share on my server directly imported to
local machine via fstab

for this my digikam4.db and also my thumbnails-digikam.db is on local hd


DigiKam is configurated to store all metadata in picture (I have a
backup in a safe place!)



My question now is: Is the face rectangle also stored in picture or is
it in database?
I ask this because I had problems when choosing all pictures (~ 95.000
pictures) in one part than generating thumbnails and fingerprints
crashes DigiKam. For this I only choose a part of all of pictures to get
faces named but will I loose this named faces now when choose only other
part of pictures?

If faces are stored in pictures and there will be no loss What can I do
later to get access to all pictures including fingerprints and thumbnails?


Maybe my observation is related to some wrong work flow but I see
several times that after I ordered faces to pictures next time I start
DigiKam again some faces are connected to wrong name.

After this I can't find a solution to bring this faces back to
"unknown". Even if I choose this tag and I hit "OK" there is no change
and I can not confirm in any other way. Do I make a mistake here?
Only option is to delete the face rectangle completely or to confirm
that this is no face - but both is not I want to do.

I would like to bring this faces back to "unknown" because some of this
faces I do not know and if I have them in one place every visitor can
easily help me to name this "unknown faces".

Thanks in advanced

Johannes


PS Do you see a chance to get the mysql database back on server so we
can use same database from several client machines (not at same time)?

Both. face region are stored to XMP. Look with metadata viewer for details.

Backtrace of the crash please.

There is already a report about but under Windows. No suitable
backtrace can be generated.

When you generate fingerprint did you use maintenance tool ? Did yiu
use multi-core option ?

Select and image in icon view and :

1/ look if face region tags are visible in XMP (MP and MWGR
namespace). Example :

2/ try to use More>Sync DB with metadata from Caption & Tags side bar.

If we can find a student to work on it. For the moment no. We are
focused to KF5 port. After we will see.

as you can see on my screenshot I do not have the part "MP" and no
"MGWR". And how do you get this view in multi line display? I have only
one endless line. Is this OS related? Or is there an option to switch on?

sorry, but I do not get a backtrace too on my openSUSE, I tried but it
seems that there is no debug information

yes, switch to use all cores is set

sorry, I do not find this option. You have a screenshot? Maybe my German
translation is kidding me

There is an option on the top of metadata view to switch tags filter
mode. Set no filter to show all.
