I want a translucent PNG overlayed on top of my screen (above all windows). I'm using this to mark a visible region while streaming.

So far I've figured out that qiv -transparent filename.png will add a mask to the window, but it's a boolean mask. I don't get translucent fading with the alpha channel.

I know several effects have opacity, and I can sent window opacity, so I'm hoping there's some way to display an image that way.

What program, tool, or widget can I use to blend an image onto the top of the desktop?

I was unable to find a stock solution so ended up modifying the pqiv program to achieve this.

I wrote an article explaining details.

The branch of pqiv is here. The command-line options for the desired effect are:

pqiv --click-through --keep-above --transparent-background --hide-info-box  filename.png

    Make sure to use ./configure --gtk-version=3 if it won't build – Heath Mitchell Oct 23 '20 at 15:18
  • I cloned from 'https://github.com/mortoray/pqiv', compiled it. --click-through and --keep-above are unknown options.... If i dont use them, it works – Vitor Abella Apr 29 '22 at 02:13
  • @VitorAbella make sure to checkout the correct feature branch After cloning and going inside directory: git checkout feature/click-through – Mossab Apr 16 '23 at 23:21
