winc - Windows Capture

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);
}

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