I am myself developing a crate to create wallpapers, and as it is now I feel reluctant to use wallpaper as a dependency because the set_from_url pulls in many dependencies which I am not using (I only need the set_from_path function), and I would feel bad forcing my users to compile reqwest, url and all of their many dependencies.
Apart from this single drawback, wallpaper is the best crate of its kind that I could find, and I would love for it to be a bit more lightweight for my use-case.

Case in point:

$ cd wallpaper.rs
$ cargo tree | wc -l
312

I know that there are duplicates, but this is still a bit much.

Proposal: make reqwest and url optional dependencies. Of course, they would be opt-out to avoid breaking any other crates.

If this proposal seems reasonable to you, I already have a pull request ready that implements it by adding a "from-url" feature enabled by default and that one can opt out of:

$ cd wallpaper.rs
$ cargo tree --no-default-features | wc -l
5

This simple example does not change my background:

fn main() {
  wallpaper::set_from_path("/home/septias/Pictures/wallpapers/t3_10aryph.png");
}

It would be great to be able to change the wallpaper of the lock screen on the OSs that support it.

PS. Do you know any cross-platform library that does the same thing?

When using this library on MacOS, the wallpaper does not change. Only the login screen changes after executing "killall Dock" in the command line, but the wallpaper remains unchanged.

can we get a get_mode() implementation which checks and returns the wallpaper mode

On macOS, the set_from_path function only sets the wallpaper of the desktop that's currently in the foreground. If a fullscreen app is active, nothing happens.

Currently for gnome dark mode, I am having to point to this git repository - it would be pretty helpful if you pushed 4.0.0 to crates.io
:)

It would be a nice feature, if it is possible to set different wallpaper on different screens.

For macos 14, default wallpaper is /System/Library/CoreServices/DefaultDesktop.heic, wallpaper::get() return Err("osascript exited with status code 1")

osascript -e 'tell application "System Events" to picture of current desktop'

I'm trying to run this minimal example

use wallpaper;

fn main() {
    wallpaper::set_from_path(
        "<private>/t3_reaw76.jpeg",
    )
    .unwrap()
}

but it doesn't set the new background even though the image exists an can be set manually.

When I try to change the wallpaper in XFCE (Arch Linux) I get this error:
thread 'main' panicked at 'called Result::unwrap()on anErr value: "xfconf-query exited with status code 1"', src/libcore/result.rs:1084:5

This is because this library uses this command to change the wallpaper in XFCE: xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/workspace0/last-image -s PATH, but in Arch (I do not know other OS) the property is /backdrop/screen0/monitorLVDS1/workspace0/last-image instead of /backdrop/screen0/monitor0/workspace0/last-image

When I add a command to cron attempt to change wallpaper automatically, but it failed.
My OS is Ubuntu Linux.
Please fixed this issue.

It looks like that the current master is broken on windows and mac:
