Triangle in embedded_graphics::primitives::triangle - Rust

pub struct Triangle {
    pub vertices: [Point; 3],
}

Triangle primitive

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

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::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)?;

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]);

The vertices of the triangle.

Create a new triangle with the given vertices.

Creates a new triangle from a Point slice.

This method will panic if the given slice is not exactly 3 items long.

Returns true if the given point is inside the shape.

Writes the defmt representation of self to fmt.

Tests for self and other values to be equal, and is used by ==.

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

This method returns an ordering between

and

values if one exists.

Tests less than (for

and

) and is used by the

operator.

Tests less than or equal to (for

and

) and is used by the

operator.

Tests greater than (for

and

) and is used by the

operator.

Tests greater than or equal to (for

and

) and is used by the

operator.

Iterator over all points inside the primitive.

Returns an iterator over all points inside the primitive.

Converts this primitive into a Styled.

Returns the bounding box using the given style.

Translate the triangle from its current position to a new position by (x, y) pixels, returning a new Triangle. For a mutating transform, see translate_mut.

let tri = Triangle::new(Point::new(5, 10), Point::new(15, 20), Point::new(8, 15));
let moved = tri.translate(Point::new(10, 10));

assert_eq!(
    moved,
    Triangle::new(Point::new(15, 20), Point::new(25, 30), Point::new(18, 25))
);

Translate the triangle from its current position to a new position by (x, y) pixels.

let mut tri = Triangle::new(Point::new(5, 10), Point::new(15, 20), Point::new(10, 15));
tri.translate_mut(Point::new(10, 10));

assert_eq!(
    tri,
    Triangle::new(Point::new(15, 20), Point::new(25, 30), Point::new(20, 25))
)
