在 Windows 10 中获取夜灯模式的状态

问题描述

我正在使用

背景:我正在研究环境光实现，如果启用了夜灯模式，颜色偏移不会反映在我屏幕周围的 LED 中，因此屏幕内容和屏幕周围"之间的颜色会关闭.

可以查看

GetDeviceGammaRamp

来自 Win API 的函数.将输出与夜灯 ON 和 OFF 进行比较，您应该可以检测到它.

或者您可以尝试监视此 Reg 键的更改

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionCloudStoreStoreCacheDefaultAccount$$windows.data.bluelightreduction.settingsCurrent

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.

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

or

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

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

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'.

You can check the output of

GetDeviceGammaRamp

Function from the Win API. Compare the output to Night Light ON and OFF and you should detect it.

Or you can try to monitor this Reg key for changes

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionCloudStoreStoreCacheDefaultAccount$$windows.data.bluelightreduction.settingsCurrent
