can also be used in non-KDE X11 desktop environments.
which doesn't really explicitly say much, and in fact the only tool I could find that claimed to be able to support everything was ksnip, which seems to work fine with wlroots but beyond that https://github.com/ksnip/ksnip#known-issues outlines the situation well enough; KDE is at least only temporarily broken, but GNOME isn't going to improve because GNOME did that on purpose. Now, that readme says you can use xdg-desktop-portal, but I have a GNOME+Wayland machine on hand, and I couldn't get it to actually work. I think what's supposed to happen is that every time I do a screenshot it prompts for permission, which I wanted to verify so I could complain that that was totally unreasonable, but what actually happens is that it just fails, which is... not better. Oh, and while searching for solutions to that I found flameshot, but that just refuses to even run. So... maybe someday the portal solution will work; in the meantime, I feel comfortable describing the situation as Wayland not having a uniform working way of taking screenshots.
[0] In particular, so we can avoid the situation from X11 where a load of drawing primitives are baked in that nobody has any use for anymore.

slop

5 839 3.7 C++

slop (Select Operation) is an application that queries for a selection from the user and prints the region to stdout. (by naelstrof)

Project mention: selx - A Minimal X11 selection tool | /r/suckless | 2023-10-23

Since selx is meant to be minimal, it doesn't support some of the fancy stuff such as slop's custom opengl shaders etc.

InjectableGenericCameraSystem

132 684 1.5 C++

This is a generic camera system to be used as the base for cameras for taking screenshots within games. The main purpose of the system is to hijack the in-game 3D camera by overwriting values in its camera structure with our own values so we can control where the camera is located, it's pitch/yaw/roll values, its FoV and the camera's look vector.
