[digiKam-users] Accessing foto collections from different machines?

Tonio Kroeger
Hi all,

I am accessing my photo collection from different machines. Currently I do this by "ssh -X". It is working, even via WLAN it is okay. My main issue is that the remote machine is a laptop and sometimes is shutdown or suspended and I have no chance to get informed before.

Now I setup my raspberrypi 4 as a nfs-server and for accessing the pictures it is fine. So I am tempted to also copy the digikam-sqllite database on this nfs-share. Now I learned from the doku that this is highly discouraged. SQLlite does not load the database into main memory? In my case just 131MB? Is there an alternate idea for my setting? I might set up a mysql-server on the raspberrypi to hold the database?

Any hint is highly appreciated.

What I do, I mount the shared folders where I keep my pictures, but I use
local databases. I store all my metadata in the pictures (or in sidecars),
and let each digikam installation to scan for changes at startup.

I access my collection through internet (via VPN), and the performance is ok
as long as I keep the database in my local hard drive.

That way, several family members can access the picture collection from
several computers/locations.

I can't offer suggestions regarding the Pi, SQL & network connection
(beyond my level of expertise), but it ought to be possible to enable
Wake on LAN for the laptop (may require installing additional software).
It might not work for a shutdown machine, but should wake a sleeping
computer up.  Even if it's in a very deep sleep.

I've recently been playing with some of these issues as a result of an
upgrade to Kubuntu20.   If you are talking about seeing them as a
removable collection, you could add them to your current default setup,
but this might involved re-initializing the database, which for 130MB 
(just?) might take a while. At least for me, it could be that this is
because I store the metadata in the JPG, and not in a sidecar file

I believe you can also trick digikam in starting up with a different
~/.config/digikamrc file, e.g. I believe this works:

     digikam --database-directory /photos/db --config /photos/db/digikamrc

but even in that case the identifier in the AlbumRoots would need to be
adjusted, and perhaps the specificPath as well, but then you should be
able to be "up" right away.

I didn't like this idea, since I would want all of the pictures in the
same database.

I am still in the middle of this upgrade, and as I posted in another
message, my trickery defeated me trying to say what's a removable and
what's a local collection.

If you look in the Collection Settings, there is also a Network Shares
option.

[digiKam-users] UI Zoom for maps?

Tóth Csaba
Hello!

I used the digikam with HDPI (on windows 10, its the . The default UI
fine for me, but the map's UI are to small. Its unreadable, the small
lines i can only "feel" and not "see".

I'd like to somehow zoom the map, more technically: the map is in an N*M
window. what I like: it is in the same N*M window, but the renderer just
download an n*m screen, and scale it up to N*M (about 2-2.5 scale)

How can I change the zooming factor to the map?

(or how can i set up the Marble in windows?)

Thanx

Csaba
