Spot - A simple 2D graphics library for drawing images.

Example

use spot::{Context, Spot, Image, ImageDrawOptions, switch_scene};

struct MyApp {
    image: Image,
}

impl Spot for MyApp {
    fn initialize(_context: Context) -> Self {
        let rgba = vec![255u8; 256 * 256 * 4];
        let image = Image::new_from_rgba8(256, 256, &rgba).unwrap();
        Self { image }
    }

    fn draw(&mut self, context: &mut Context) {
        let mut opts = ImageDrawOptions::default();
        opts.position = [spot::Pt(100.0), spot::Pt(100.0)];
        opts.scale = [0.78125, 0.78125];
        self.image.draw(context, opts);
    }

    fn update(&mut self, _context: &mut Context, _dt: std::time::Duration) {}
    fn remove(&self) {}
}

fn main() {
    spot::run::<MyApp>(spot::WindowConfig::default());
}

// Scene switching example:
// switch_scene::<NewScene>();  // Switches to NewScene
