screensnap

A simple screenshooting program written in Rust.

Currently only supports Windows; PRs are welcome to add support for other platforms.

Usage

Just run the executable. As of writing, no command line arguments are needed.

While the process is running, it waits for you to press the Print Screen key. It doesn't do anything else (besides setting up the window and OpenGL context so that they're ready as soon as you press the Print Screen key, but that only happens once at startup).

When you press Print Screen, your screen will darken. This is the screensnap cropping window. You can select a rectangular area by clicking and dragging with the left click of the mouse. Alternatively, holding shift will allow you to crop the screenshot to a window of your choice.

As soon as you release, the cropping window closes, and the area you've selected gets copied to your clipboard. Most softwares support pasting images directly from the clipboard.

Key bindings and keystrokes

System-wide

Key/keystroke	Action
Print Screen/SysRq/Snapshot	Take a screenshot (opens the cropping window)

In the cropping window

The cropping window is the window that opens when you press Print Screen. It darkens the screen and lets you select a rectangle you want to copy to the clipboard. It has a few handy keystrokes:

Key/keystroke	Action
Shift (hold)	Crop screenshot to individual windows
Ctrl-Shift-Q	Kill the process (disables system-wide keystrokes)
