   It’s a small script… but impressive!

   is there a way to include the wallpaper? Like draw from wallpaperview to canvas?

   thanks for the script! playing around with it, and it seems to read the invisible items on the desktop. can it be modified to read only the visible items?

   
   

   
   

   how do you get the real time effect … it seems to “remember” past background images for me rather the most recent/current background

   
   

   
   

   note: i tried running the script on item resume, but can’t get it to be real time. should i be putting the entire script into a function and using settimeout instead?

    run it in position changed of the desktop. I haven’t thought about invisible items, because I don’t have them… but that should be easy to do.

   Lukas Morawietz thanks, position changed worked perfectly!

   
   

   can you point me in the right direction on how to exclude the invisible items? add a criteria in the “for” loop for z items?

   Lukas Morawietz this is difficult. For static system wallpaper you can use WallpaperManager.peekDrawable but there is no way with LWP (for security reasons)

   Pierre Hébert and if I have a static wallpaper, can I get the scroll position of it?

    Lukas Morawietz no, the launcher provides “offsets” but it is up to the android framework to compute the actual translation (and scale). I have seen manufacturers tuning this computation making the detection of actual scroll values unreliable.
