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.
Usage: thumbnailer-bridge [OPTIONS] [FILE]...
Arguments: [FILE]...
Options:
-t, --thumbnail Print path to thumbnail if it exists and up to date
-f, --flavor
This is how you request thumbnails. Flavor -f or --flavor is usually responsible for the size of a thumbnail.
sh
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.
sh
$ thumbnailer-bridge --listen
/home/user/pictures/meal-2023-02-22.png
/home/user/pictures/booty.jpg
/home/user/books/how_to_eat_chicken.epub
...
You will find your thumbnails at ${XDG_CACHE_HOME:-~/.cache}/thumbnails/(flavor)/.
To find a thumbnail, corresponding to your file, you can use -t or --thumbnail flag.
sh
$ thumbnailer-bridge -f x-large -t ~/pictures/cat.png
/home/user/.cache/thumbnails/x-large/722b4dbaa8bf716e9f9f7f33f72fd9d4.png
