I want to sort of recreate macOS 15’s dynamic wallpaper, and downloaded this set of 8 wallpapers which are most / all the colors it cycles through. On Hyprland, I want to cycle through them throughout the day, but also slowly transition from one wallpaper to another for an hour or longer, crossfading / blending them.
I did some searching, and neither timewall or adi1090x/dynamic-wallpaper can do it. I looked at making my own script to blend images once every 60 secs, but I’m not sure how to quickly crossfade images. This command takes ~15 secs, I feel this should possible much faster with or without imagemagick: magick composite -blend 50 wallpaper1.png wallpaper2.png output.png.

Look at awww, it can handle transitions for you and is pretty easy to write a script for.
swww is good for this as well!
awww is actually just swww renamed. The author felt guilty about the name because it was initially “the final solution to your wayland wallpaper woes”, and they weren’t aware of the connotations of “final solution” when they named it that.
Ohhhh! Right! I remember reading a post about that now you say it.
I wanted to say this also. Try that one.
