Pronounced "wink"

A crate for windows screen capture.

Usage

See tests.rs for examples.

#[test]
fn region_screenshots() {
    let monitors = get_all_monitors().unwrap();
    let mut capturers = Vec::new();

    for monitor in monitors {
        let p0 = monitor.info.rect.top_left();
        let p1 = p0.translate(100, 100);
        let region = RECT::from_corners(p0, p1).translate(100, 100);
        let capturer = get_monitor_capturer(Rc::new(monitor), region);
        capturers.push(capturer);
    }
    std::fs::create_dir_all("target/capture").unwrap();

    let mut images = Vec::new();
    for capturer in capturers.iter() {
        // capture
        let capture = capturer.capture(&mut Metrics::None).unwrap();

        // save image
        let mon_name_good = capturer.monitor.info.name.replace(r"\\.\", "");
        let path = format!("target/capture/region-{}.png", mon_name_good);
        capture.save(path).unwrap();
        images.push(capture);
    }

    assert_no_transparency(&images);
}

My understanding is that the licenses used in our projects are compatible. If something is wrong, please let me know!

The modifications aim to reduce redundant work for successive screen capture calls.
