Description Marcel Wiesweg 2004-10-21 19:38:57 UTC

Version:            (using KDE KDE 3.3.1)
Installed from:    SuSE RPMs

I am using digikam on a slow machine measured by today's standards (PIII 500, 192MB RAM). This means that thumbnail generation of large JPEGs requires a lot of my CPU. While overall GUI performance is usually very satisfying, during creation of larger thumbnails, with 100% CPU load, working on the PC or even digikam is not really possible.

For this reason I would appreciate a menu option "Generate all thumbnails" which opens a modal dialogue and begins to generate all not-yet-created thumbnails. (Kimdaba has this BTW)

This is mostly for first-time setup, but I would also use it when importing a large number of new photos.

I second that (was about to create a new bugzilla entry, but this one is rather fine). There are two possibilities:
1) generate all "missing" thumbnails when the user requires it from a menu, with a progress bar somewhere to show how far along the process is
2) generate thumbnails in the background whenever CPU activity is low

The third possibility would be to give the choice to the user :-)

I have a fast machine, but slow (external USB/CD/DVD) drive and big images (more than 3000x2000 px, 2MB). I would like to have thumbnails on "fast" storage (configurable path, eg. "Thumbnail Library Path" below "Album Library Path" in Settings->Albums).
I would like also to see thumbnails even for "missing" imges - see bug #119228

@Marcel: which version of digikam was that? if it was prior to 0.8.0 can you check the current version, should be a lot better
@nicolas: this is only a one time action, as soon as the thumbs are generated the first time, it will be a lot faster the second time
@michal the thumbnails are stored following the desktop standard, we do not agree completely with them, but I think you can link .thumbnail from your home directory to a faster place if needed.

Comment 4 Marcel Wiesweg 2005-12-30 20:44:41 UTC

This was an old version, probably the 0.7.x series. Meanwhile it is probably much faster, but I am also working on a new computer, so I cannot test this for slow computers any more.

ok, thanks.

Comment 6 Nicolas Brisset 2006-01-29 00:43:57 UTC

I see that this request is supposed to be "resolved", but I don't think the functionality has been implemented... I have several thousand images, and every time I go to a folder I haven't visited yet, I have to wait for the thumbnails to be generated, which is not so nice. Especially when I think of the hours during which the computer is just idle. So I'm tempted to reopen this bug. IS that OK ?
The idea would be to just add a tool menu somewhere to generate ALL image thumbnails (that is, for the whole image collection). A progress dialog with percent done and optional current image name would be nice as well :-)

Comment 7 Nicolas Brisset 2006-03-15 01:08:43 UTC

Any chance we can "reactivate" this request ?

Comment 8 Christo 2006-08-10 01:07:48 UTC

Comment 9 Gehold Bertin 2007-01-25 19:58:32 UTC
