[Bug 196470] New: Wish: Update files with metadata from DB

https://bugs.kde.org/show_bug.cgi?id=196470

           Summary: Wish: Update files with metadata from DB
           Product: digikam
           Version: 1.0.0-beta1
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel@...
        ReportedBy: linux@...


Version:           1.0.0-beta1 (using KDE 4.2.4)
OS:                Linux
Installed from:    Debian testing/unstable Packages

Hi,

it would be nice to have the possibility to update selected image files with
metadata, instead of update *all* files in the database.

Suggested workflow:
- Import (possibly huge) images from camera
- add keywords, notes, descriptions to digikam's database
- select images or folders and choose new option "Write metadata to files"
  (this should include all metadata e.g. photographer, copyright, description,
keywords etc. in IPTC, XMP and exif).

This would gain an improved performance. I store all information in the files
for better interoperability. But every write operation to the files costs some
time, especially on large files.

Thanks in advance!

But It's already exist. Go to an album, take selection, open right sidebar, go
to comments and tags and see More combo on the bottom...

Thanks for the hint, I did not noticed this function.

At least, this doesn't seem not work, at least I'm unable to figure it out.

If I disable the options to store keywords and caption in files in general
settings --> metadata, no changes will be written to IPTC headers, even with
that function.

If I enable these options, changes will be written to metadata as soon as I hit
the "Apply" button in the sidebar. For 10 JPEGs, 5MB each, this needs round
about 5 seconds.

Thanks for your help!
Michael.

I'm sorry, it's not :-)

I would like to make my comments to the pictures, using the fast storage in
digikam's DB, only.

When I'm finished, I'd "export" the comments to the files, using a slow
write-to-file operation.

My feature request #181708 is somehow related (define tags that are written to
database only).
In my opinion that one can be closed if this wish here was implemented as
suggested.

I also found a bug (#214038), that if you tag more images while the first "job"
is still running, the first one is cancelled.

A solution for this may be to block while updating the image metadata, so this
wish here becomes even more important.
