Triangle primitive

§Examples

§Create some triangles with different styles

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

// Triangle with red 1 px wide stroke
Triangle::new(Point::new(40, 20), Point::new(50, 25), Point::new(60, 60))
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::RED, 1))
    .draw(&mut display)?;

// Triangle with translation applied
Triangle::new(Point::new(40, 20), Point::new(50, 25), Point::new(60, 60))
    .translate(Point::new(-10, -20))
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::GREEN, 1))
    .draw(&mut display)?;

§Create a triangle from a slice

A triangle can be created from a &[Point] slice. If the slice is not exactly 3 elements long, the from_slice method will panic.

use embedded_graphics::{geometry::Point, primitives::Triangle};

let p1 = Point::new(5, 10);
let p2 = Point::new(15, 25);
let p3 = Point::new(5, 25);

let tri = Triangle::from_slice(&[p1, p2, p3]);

Fields§

§vertices: [Point; 3]

The vertices of the triangle.
