Crate spottedcat 

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

Example

use spottedcat::{Context, Spot, Image, DrawOption, switch_scene};

struct MyApp {
    image: Image,
}

impl Spot for MyApp {
    fn initialize(_context: &mut Context) -> Self {
        let rgba = vec![255u8; 256 * 256 * 4];
        let image = Image::new_from_rgba8(256u32.into(), 256u32.into(), &rgba).unwrap();
        Self { image }
    }

    fn draw(&mut self, context: &mut Context) {
        let opts = DrawOption::default()
            .with_position([spottedcat::Pt::from(100.0), spottedcat::Pt::from(100.0)])
            .with_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() {
    spottedcat::run::<MyApp>(spottedcat::WindowConfig::default());
}

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