Description jan.claussen10 2021-01-17 15:45:02 UTC

SUMMARY
When you use the "Picture of the day" function that automatically switches wallpapers, you have to set a background color. It would be nice if this background color could be automatically found. At least it should be able to toggle between black and white - so determine whether the wallpaper is predominantly dark or light. 

This way it would be possible to fully use the icon painting feature of the Latte Dock, which paints the icons black or white relative to the background color.

I actually don't understand what this background color is needed for. Latte actually can determine the predominant color of a picture itself. This works with all other wallpapers but not in this Picture of the Day mode, because it will use the background color instead of the wallpaper.

So I think the easiest way would be to get rid of this background color.

FWIW you don't have to set a background color; only when using the "Centered" or "Scaled, keep proportions" settings.

I always have to set a background color. No matter what I choose.
