XCap

English | 简体中文

XCap is a cross-platform screen capture library written in Rust. It supports Linux (X11, Wayland), MacOS, and Windows. XCap supports screenshot and video recording (WIP).

Features

• Cross-platform: Supports Linux (X11, Wayland), MacOS, and Windows.
• Supports multiple screenshot modes: Can take screenshots of the screen and windows.
• Supports video recording: Supports recording of the screen or window (WIP).

Examples

• Screen Capture

use std::time::Instant;
use xcap::Monitor;

fn normalized(filename: &str) -> String {
    filename
        .replace("|", "")
        .replace("\\", "")
        .replace(":", "")
        .replace("/", "")
}

fn main() {
    let start = Instant::now();
    let monitors = Monitor::all().unwrap();

    for monitor in monitors {
        let image = monitor.capture_image().unwrap();

        image
            .save(format!("target/monitor-{}.png", normalized(monitor.name())))
            .unwrap();
    }

    println!("运行耗时: {:?}", start.elapsed());
}

• Screen Record

use std::{sync::Arc, thread, time::Duration};
use xcap::Monitor;

fn main() {
    let monitor = Monitor::from_point(100, 100).unwrap();

    let video_recorder = Arc::new(monitor.video_recorder().unwrap());

    let video_recorder_clone = video_recorder.clone();
    thread::spawn(move || {
        video_recorder_clone
            .on_frame(|frame| {
                println!("frame: {:?}", frame.width);
                Ok(())
            })
            .unwrap();
    });

    println!("start");
    video_recorder.start().unwrap();
    thread::sleep(Duration::from_secs(2));
    println!("stop");
    video_recorder.stop().unwrap();
    thread::sleep(Duration::from_secs(2));
    println!("start");
    video_recorder.start().unwrap();
    thread::sleep(Duration::from_secs(2));
    println!("stop");
    video_recorder.stop().unwrap();
}

• Window Capture

use std::time::Instant;
use xcap::Window;

fn normalized(filename: &str) -> String {
    filename
        .replace("|", "")
        .replace("\\", "")
        .replace(":", "")
        .replace("/", "")
}

fn main() {
    let start = Instant::now();
    let windows = Window::all().unwrap();

    let mut i = 0;

    for window in windows {
        // 最小化的窗口不能截屏
        if window.is_minimized() {
            continue;
        }

        println!(
            "Window: {:?} {:?} {:?}",
            window.title(),
            (window.x(), window.y(), window.width(), window.height()),
            (window.is_minimized(), window.is_maximized())
        );

        let image = window.capture_image().unwrap();
        image
            .save(format!(
                "target/window-{}-{}.png",
                i,
                normalized(window.title())
            ))
            .unwrap();

        i += 1;
    }

    println!("运行耗时: {:?}", start.elapsed());
}
