问题描述
限时送ChatGPT账号..例如在 Ubuntu 中,您可以使用 Super-M 来反转屏幕颜色(需要桌面效果,请参阅 [1]).其他操作系统也有类似的能力,尽管我并不真正关心 Linux 以外的任何东西.
In Ubuntu, for example, you can use Super-M to invert the screen colors (requires desktop effects, see [1]). Other OSes have similar abilities, although I'm not really concerned with anything other than Linux.
如果我想编写一个在运行时反转屏幕颜色的简单程序,我应该研究哪个 API?
Which API should I look into if I want to write a simple program that, when run, inverts the screen colors?
我使用 API 的语言对我来说并不重要.我对 C/C++/Bash/Perl/Python 非常熟悉,所以我可以用任何最容易访问这个 API 的语言来解决这个问题.需要在 Ubuntu 上工作,在其他类似的 *nix 上工作并不是很重要.
The language that I use the API from doesn't particularly matter to me. I am familiar enough with C/C++/Bash/Perl/Python that I can hack this up in whatever language has the easiest access to this API. Working on Ubuntu is required, working on other similar *nixes is not terribly important.

推荐答案
你可以使用 xcalib 来做些什么你想要.
You could use xcalib to do what you want.
例如,用于反转屏幕颜色的简单 bash 脚本如下所示:
For example, a simple bash script to invert the screen colors would look like this:
#!/bin/bash
xcalib -invert -alter
