获取Windows 10中夜灯模式的状态 [英] Get status of night light mode in Windows 10

问题描述

我正在使用

I am using the desktop duplication api to grab the screen content and as it turns out, the new night light mode ('Nachtmodus' in German) is not applied in the grabbed screen content.

如何读取(如果可能，直接在C#中)夜间模式状态(启用，色偏量)?

How do I read (if possible directly in c#) the night mode status (enabled, color shift amount)?

或

如何告诉Windows使用桌面复制api给我变色的图像?

How can I tell Windows to give me the color shifted image using the desktop duplication api?

基本上，我想知道这些红色框中配置的状态:

Basically, I want to know the state of what is configured inside these red boxes:

背景:我正在研究无聊的实现，如果启用了夜灯模式，颜色偏移不会反映在屏幕周围的LED上，因此屏幕内容和屏幕周围"之间的颜色是关闭的.

Background: I am working on an ambilight implementation and if the night light mode is enabled, the color shift is not reflected in the LEDs around my screen and so the colors are off between screen content and 'around screen'.
