Rust Graphics Lib

This is a simple wrapper around Pixels, it provides basic shape, image and text rendering.

This boilerplate code is needed to use it:


let event_loop = EventLoop::new();
let mut input = WinitInputHelper::new();
let (mut window, mut graphics) = setup((240, 160), WindowScaling::Auto, "Doc Example", &event_loop)?;


event_loop.run(move |event, _, control_flow| {
    if let Event::RedrawRequested(_) = event {
        if graphics.pixels
        .render()
        .map_err(|e| eprintln ! ("pixels.render() failed: {:?}", e))
        .is_err()
        {
            *control_flow = ControlFlow::Exit;
            return;
        }
    }

    //put your rendering code here

    if input.update(&event) {
        if input.key_pressed(VirtualKeyCode::Escape) || input.quit() {
            *control_flow = ControlFlow::Exit;
            return;
        }

        if let Some(size) = input.window_resized() {
            graphics.pixels.resize_surface(size.width, size.height);
        }

        //put your update/input handling code here

        window.request_redraw();
    }
});

Using the library is as simple as:

 graphics.draw_text("Some text", 9, 1, 1, TextSize::Normal, BLACK);
 graphics.draw_line(30, 30, 100, 120, BLUE);
