(these screenshots were taken at different times so they’re not exact, but if we’re planning to do this, we could make sure the screenshots are pixel-perfect other than the color scheme change)
@cassidyjames Would be cool if the screenshot tool could take both light and dark screenshots at the same time
@tbernard yep, someone suggested that and I'm thinking of how to make it work. It might not be super reliable but it would be dope. We'd need a system wide dark style preference, and the app would need to support it. 😜
@tbernard @cassidyjames not possible really. You can do something like elementary does for the conceal text option, i.e. take a light screenshot, switch everything to dark, wait until animations have ended, take a dark screenshot, switch everything back. But that would fail if there's any animation.
@exalm @tbernard yeah it would work like the conceal text. And there's an experimental Gala branch that adds an API for transitioning cleanly between light and dark; I think it has (or could have) some sort of callback for when the transition is over so Screenshot could wait for that, then snap, then transition back.
@cassidyjames @exalm @tbernard a proper way of doing this is introducing Wayland/X11 protocol extensions that ask the app to render itself in the given style and send the buffer over, without changing how the app appears to the user. Then you don't have to rely on hacks with waiting for animations to finish, etc., except using them as a fallback
I've wanted to do this for *vector* screenshots for a long time, but never got around to actually doing it
@exalm @cassidyjames @tbernard true, that's why you'd need a fallback for clients using other toolkits. For X11, it doesn't have to be an actual protocol between the clients and the X server; it can just be something with properties and invisible windows between the client and the compositor; though I admit I've never done anything like that on X11.
