Screenshots is a cross-platform screenshots library for MacOS, Windows, Linux (X11, Wayland) written in Rust. It provides a simple API for capturing screenshots of a screen or a specific area of a screen.

The following example shows how to capture screenshots of all screens and a specific area of a screen.

use screenshots::Screen;
use std::{fs, time::Instant};

fn main() {
  let start = Instant::now();
  let screens = Screen::all().unwrap();

  for screen in screens {
    println!("capturer {screen:?}");
    let mut image = screen.capture().unwrap();
    let mut buffer = image.buffer();
    fs::write(format!("target/{}.png", screen.display_info.id), buffer).unwrap();

    image = screen.capture_area(300, 300, 300, 300).unwrap();
    buffer = image.buffer();
    fs::write(format!("target/{}-2.png", screen.display_info.id), buffer).unwrap();
  }

  let screen = Screen::from_point(100, 100).unwrap();
  println!("capturer {screen:?}");

  let image = screen.capture_area(300, 300, 300, 300).unwrap();
  let buffer = image.buffer();
  fs::write("target/capture_display_with_point.png", buffer).unwrap();

  println!("Elapsed time: {:?}", start.elapsed());
}

The Screen struct represents a screen capturer and provides the following methods:

• Screen::new(display_info): Get a screen from the display info, returns a Screen.
• Screen::all(): Get all screens, returns Result<Vec<Screen>>.
• Screen::from_point(x, y): Get a screen from a point, returns Result<Screen>.
• screen.capture(): Capture a screenshot of the screen, returns a image.
• screen.capture_area(x, y, width, height): Capture a screenshot of the designated area of the screen, returns a Result<Image>.

The Image struct represents a screen screenshot image and provides the following methods:

• Image::new(width, height, buffer): Get an image from the width, height, and RGBA buffer, returns an Image.
• Image::from_bgra(width, height, buffer): Get an image from the width, height, and BGRA buffer, returns Result<Image, EncodingError>.
• image.width(): Get the image width, returns u32.
• image.height(): Get the image height, returns u32.
• image.buffer(): Get the image buffer, returns Vec<u8>.

On Linux, you need to install libxcb, libxrandr, and dbus.

Debian/Ubuntu:

apt-get install libxcb1 libxrandr2 libdbus-1-3

Alpine:

apk add libxcb libxrandr dbus
