Triangle primitive

§Examples

The macro examples make for more concise code.

§Create some triangles with different styles

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

// Triangle with red 1 px wide stroke
Triangle::new(Point::new(50, 20), Point::new(60, 35), Point::new(70, 80))
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::RED, 1))
    .draw(&mut display)?;

// Triangle with translation applied
Triangle::new(Point::new(50, 20), Point::new(60, 35), Point::new(70, 80))
    .translate(Point::new(65, 35))
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::GREEN, 1))
    .draw(&mut display)?;

§Create a triangle from an array of points

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);

// Owned
let tri = Triangle::from_points([p1, p2, p3]);

// Or borrowed
let tri_ref = Triangle::from_points(&[p1, p2, p3]);

Fields§

§p1: Point

First point of the triangle

§p2: Point

Second point of the triangle

§p3: Point

Third point of the triangle

Implementations§

source§

impl Triangle

source

pub const fn new(p1: Point, p2: Point, p3: Point) -> Self

Create a new triangle with a given style

source

pub fn from_points<P, I>(points: P) -> Self
where I: Into<Point> + Copy, P: Borrow<[I; 3]>,
