This tool makes requests to create thumbnails through D-Bus following org.freedesktop.thumbnails.Thumbnailer1 specification. It doesn't create thumbnails on it's own, but acts as a bridge between your file manager and thumbnailer.
To create thumbnails you will need a daemon, like tumbler.
What are the advantages of using this instead of a shell script with dbus-send?
dbus-send.libmagic and dbus without additional processes.``` Bridge between your file manager and thumbnail daemon.
thumbnailer-bridge [OPTIONS] [FILE]...
Arguments: [FILE]...
Options:
-f, --flavor
This is how you request thumbnails. Flavor -f or --flavor is usually responsible for the size of a thumbnail.
bash
thumbnailer-bridge -f x-large $PWD/*
I recommend you to use full path to your current directory that your file manager provides, instead of using relative path,
this way, if you're inside a sym-linked location /home/user/pictures -> /mnt/nas, your thumbnails will be preserved
if you decide to remount original location /home/user/pictures -> /mnt/nas-old
If you want to be notified when thumbnails are ready to use, add --listen flag.
bash
$ thumbnailer-bridge --listen
/home/user/pictures/meal-2023-02-22.png
/home/user/pictures/booty.jpg
/home/user/books/how_to_eat_chicken.epub
...
Your will find your thumbnails at $XDG_CACHE_HOME/thumbnails/(flavor)/(md5).png.
