A Cinnamon extension that allows to negate the window-color when you press super+i.

README

negateWindow

Used as a template for Cinnamon-plugin: 0dyseus@CinnamonTweaks

Code for inversion shader: https://github.com/maiself/gnome-shell-extension-invert-color;

Original idea: gnome invert window extention; https://extensions.gnome.org/extension/1041/invert-window-color/

Coded from 2AM - 5AM, so don't expect too much, but it works

Great extension, very useful for applications without a dark mode.

LM22.2 Great for [Character Map] to check the pictures in DarkMode to LightMode quick on a Window and way to mark a window; like pinning or tagging a window quickly also.

Works fine with Cinnamon 6.0. Thank you!

Fix just has to be merged, the original gnome extension had the same problem. https://github.com/linuxmint/cinnamon-spices-extensions/pull/388

Brilliant extension. I prefer dark mode, but sometimes I just need the high contrast of black on white, albeit for a few moments. Very useful indeed.

Best extension ever, very useful, essential for the people that like the dark mode. With this extension we don't need to wait until each of our programs implements the dark mode, we only have to invert the colors of the windows with Super + I. I'm using it with LM 19.2 Cinnamon 4.2.4 and works fine. No problems until now

On Linux Mint 20 Cinnamon 4.6.6, there is a warning when you try to enable the extension: """Extension rnbdsh@negateWindow is not compatible with current version of cinnamon. Using it may break your system. Load anyway?""" . I gave up for now. I'll try it later

It think that is fine now. And that warning does not mean it not going to work. I just means that the author haven't tried it in your current version. I used some extensions with this warning without a problem.

The extension is currently broken for me: [rnbdsh@negateWindow]: Type name Gjs_InvertWindowEffect is already registered [rnbdsh@negateWindow]: Error importing extension.js from rnbdsh@negateWindow I was able to fix it by editing: ~/.local/share/cinnamon/extensions/rnbdsh@negateWindow/extension.js and changing the `name` field on line 18 to something more unique. Changing the name property on the InvertWindowEffect to something else appears to fix it for me.

You can also add a custom key binding to bind "Super+I" to execute "xcalib -i -a" command.

Please update metadata.json file to make it compatible with Cinnamon 3.6, i.e. add string "3.6" in the list. After that this extension works just fine with latest Cinnamon.
