Graphics Lib

This is a simple wrapper around Pixels, providing basic shape drawing, bitmap text and image rendering.

Usage

Cargo

In your Cargo.toml file add toml graphics-lib = { git = "https://github.com/raybritton/rust-graphics-lib"} winit = "0.25" winit_input_helper = "0.10"

Code

This bit of boilerplate/framework must be used inside your code to use this library: ```rust let eventloop = EventLoop::new(); let mut input = WinitInputHelper::new(); let (mut window, mut graphics) = setup(240, 160, "Example", true, &eventloop)?;

eventloop.run(move |event, _, controlflow| { if let Event::RedrawRequested() = event { if graphics.pixels .render() .maperr( | e | eprintln ! ("pixels.render() failed: {:?}", e)) .iserr() { *controlflow = ControlFlow::Exit; return; }

    //put your rendering code here
}

//put your update 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 input handling code here

    window.request_redraw();
}

}); ```

Drawing is then quite simple: rust graphics.draw_text("Some text", 4, 1, 1, TextSize::Normal, BLACK); graphics.draw_image(20, 20, &image); graphics.draw_rect(1, 1, 100, 100, GREY);

Features

Both features are enabled by default

image_loading

Load files as Images

Code

rust let image = load_image("resources/example.png")?; graphics.draw_image(40,20,&image);

window_prefs

Save and restore window position and size

Code

First an instance of WindowPreferences has be created: rust let mut prefs = WindowPreferences::new( "<qualifier>", "<org name>", "<program name>", )?;

Then the file has to be created/loaded with prefs.load()?;

To set the window size and position call prefs.restore(&mut window);

To store the window size and position call prefs.store(&window);

This only saves the data to memory, to save to disk call prefs.save()?; (after store())
