Ellipse primitive

§Examples

§Create some ellipses with different styles

use embedded_graphics::{
    pixelcolor::Rgb565,
    prelude::*,
    primitives::{Ellipse, PrimitiveStyle, PrimitiveStyleBuilder},
};

// Ellipse with 1 pixel wide white stroke with top-left point at (10, 20) with a size of (30, 40)
Ellipse::new(Point::new(10, 20), Size::new(30, 40))
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::WHITE, 1))
    .draw(&mut display)?;

// Ellipse with styled stroke and fill with top-left point at (20, 30) with a size of (40, 30)
let style = PrimitiveStyleBuilder::new()
    .stroke_color(Rgb565::RED)
    .stroke_width(3)
    .fill_color(Rgb565::GREEN)
    .build();

Ellipse::new(Point::new(20, 30), Size::new(40, 30))
    .into_styled(style)
    .draw(&mut display)?;

// Ellipse with blue fill and no stroke with a translation applied
Ellipse::new(Point::new(10, 20), Size::new(20, 40))
    .translate(Point::new(10, -15))
    .into_styled(PrimitiveStyle::with_fill(Rgb565::BLUE))
