Examples

The macro examples make for more concise code.

Create some triangles with different styles

use embedded_graphics::prelude::*;
use embedded_graphics::primitives::Triangle;
use embedded_graphics::pixelcolor::Rgb565;

// Default triangle with no styling
let t1 = Triangle::new(Point::new(10, 20), Point::new(30, 40), Point::new(50, 60));

// Triangle with styled stroke from (50, 20) to (60, 35)
let t2 = Triangle::new(Point::new(50, 20), Point::new(60, 35), Point::new(70, 80))
    .stroke(Some(Rgb565::RED));

// Triangle with translation applied
let t3 = Triangle::new(Point::new(50, 20), Point::new(60, 35), Point::new(70, 80))
    .translate(Point::new(65, 35));

display.draw(t1);
display.draw(t2);
display.draw(t3);
