AsyncVoid/screenshot-rs

Get a bitmap image of a display in Rust.

screenshot-rs

Get a bitmap image of any display in Rust. This crate is hosted on crates.io.

Contributions welcome!

Examples

extern crate image;
extern crate screenshot;
use screenshot::get_screenshot;

fn main() {
	let s = get_screenshot(0).unwrap();

	println!("{} x {}", s.width(), s.height());

	image::save_buffer(&Path::new("test.png"),
		s.as_slice(), s.width() as u32, s.height() as u32, image::RGBA(8))
	.unwrap();
}

Development

• screenshot-rs has its own systems bindings. It should migrate to servo/rust-core-graphics and retep998/winapi-rs. I want to use klutzy/rust-windows, but it doesn't have the right bindings.

Known Issues

• get_screenshot leaks memory on certain error conditions, by returning before releasing OS handles. PR's welcome.
• The BMP Image in the example is rotated +90 degrees because I don't adjust for BMP idiosyncrasy.
• The PNG Image in the example has its R & B channels exchanged because PistonDevelopers/image doesn't support ARGB pixels.
