Blue light filter using Python or C++

Question

Hola Solo'ers. I wanted to make an open source project where I would be making a simple blue light filter with brightness and color adjustments.
Its planned to be cross platform, i.e, Windows as well as Linux.

I've figured the way, which is to overlay a transparent layer over the screen, and adjusting its properties would make screen look bright or dull or yellowish, i.e, its gamma n all.

But the problem is, I cannot get a way to do that.
I thought of PyQt in which there would be a window with transparency and always on top property, but I want to read the keyboard and mouse for the active window, and not the overlay window.

So, can anybody suggest a way I can overlay the screen without affecting the active window or desktop behind it?

Any programming language is okay. I just want the way I can do that.

[EDIT]

I have found "xrandr" in Linux which changes the way OS interacts with the screen. It's accomplishing my task, but its only for specific linuxes and also I want something for Windows.

Answer 1

Thank you Aradhay Mathur Alphin K Sajan for your helps.

I have found a solution that works only for Linux systems and that too specific ones.

It uses the built in "xrandr" tool that can change the way the OS interacts with the screen. I have been able to do what I wanted but only in Linux. If you get the solution for Windows, your suggestions are always welcomed.

By the way, thank you so much

Chiku I think you should use winreg module to edit registry and change HKEY_CURRENT_USER\Control Panel\Desktop

Aradhay Mathur Python

Answer 10

Aradhay Mathur I understand what you're saying, but I want an overlay type of thing that covers my whole screen, and doesnt compromise my interaction with other apps I'm clicking on or keyboard inputs.

I'm trying to make a blue light filter sort of thing. I think you can guess what type of functionality I want.

Tkinter is used for GUI making, and will therefore not be suitable for my work.

Answer 11

Aradhay Mathur
Thanks for this. I'll try to see whats that.

Answer 12

Chiku Make sure to do it in an virtual machine otherwise your system can fail

Answer 13

Aradhay Mathur
Oh yeah.. I know that😂😂

I've seen blugon, but these all are very much advanced and works only on Linux.

I just want the way I can apply a gamma layer over the screen. Its just that I want.

Other requirements like background running as a daemon, its GUI, all these I can do, but the main thing is that gamma layer

The one you told now shows how to do that in an image. I want that as a screen overlay.
