Pixel Art Extremely Blurry

[0b01]

I am rendering a 32px x 32px pixel art sprite using

        let dst = graphics::Point2::new(self.pos_x as f32, self.pos_y as f32);
        let scale = graphics::Point2::new(5., 5.);
        graphics::draw_ex(ctx, &self.image1, DrawParam {
            dest: dst,
            rotation: 0.,
            scale,
            ..Default::default()
        })?;

but the result is extremely blurry:

Resolved by setting FilterMode to Nearest:

        let mut image1 = graphics::Image::new(ctx, "/lettuce.png").unwrap();
        image1.set_filter(graphics::FilterMode::Nearest);
