Bug ID: 384059
Summary: Album > Reread metadata from images does not work
correctly
Product: digikam
Version: 5.5.0
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Tags-Captions
Assignee: digikam-bugs-n...@kde.org
Reporter: rich...@audacityteam.org
Target Milestone: ---
Whilst I was on holiday, I went through some images on my laptop, adding
captions (no tags) to them and deleting some. I now want to transfer the images
back to my main desktop PC, taking the new captions with me. The two machines
do not share a database, both use the default sqlite database. Images are
from-camera JPEGs.
Album 1:
1. I verified on the laptop (source machine) that captions had been written to
all the configured fields in the file (default list including
Xmp.tiff.ImageDescription and Xmp.dc.description).
2. I then copied the image files using scp to the desktop PC
3. I started Digikam and let it scan for new items (set to happen at startup)
4. I went to the newly copied album, and did "Album > Reread metadata from
images". In the past I have used this to read in the captions from the file
data.
5. It didn't work, and neither did the same entry on the Item menu. The
"completed" message popped up so quickly and with no disk activity that I don't
think it actually checked the images at all. Certainly much quicker than
generating a thumbnail.
6.Opening the metadata editor window at this point showed all the fields filled
in with the caption, but even after clicking OK, the image thumbnail and
captions tab of the right-hand side bar had no caption available.
7. After much cursing, I tried selecting one image, and using the "More > Read
metadata from file to Database" button in the captions tab of the right-hand
side bar. This worked, read the file and populated the thumbnail / sidebar.
Manually working through each file in the album got the information into the
database.
So this has a work-around, but a painful one for any number of images.
Album 2:
I went to repeat this, but found the other two albums have not had the captions
written to the files on the source machine. So I am stuck even earlier:
- No amount of Album > Write Metadata to Images writes it out
- Again the completed notification is instant, far faster than disk access
times on this machine.
- More > Write Metadata to each file button in the right-hand side bar is
greyed out
- I have tried turning lazy synchronisation off, no change.
- I tried altering the preferences so that an XMP sidecar is written as well as
to the image file, but no sidecar files are written!
- If I edit the caption again and then click Apply the changed caption is
written out, but this means manually altering (no-op) every single caption by
hand (as they are different to each other).
A potential work-around exists but is very labour intensive.
I think I am correct to say that when I completed editing captions on this
album (with lazy sync turned on) I just quit Digikam, without manually telling
it to sync changes, where as I synced changes by hand on Album 1. Does this
mean that sync-pending-changes-on-exit is broken as well?
I am in the process of updating to Digikam 5.6.0 to see if anything changes.
