Arc primitive

Examples

Create some arcs with different styles

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

// Arc with 1 pixel wide white stroke with top-left point at (10, 20) with a diameter of 30
Arc::new(Point::new(10, 20), 30, 0.0.deg(), 90.0.deg())
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::WHITE, 1))
    .draw(&mut display)?;

// Arc with styled stroke with top-left point at (15, 25) with a diameter of 20
let style = PrimitiveStyleBuilder::new()
    .stroke_color(Rgb565::RED)
    .stroke_width(3)
    .build();

Arc::new(Point::new(15, 25), 20, 180.0.deg(), -90.0.deg())
    .into_styled(style)
    .draw(&mut display)?;

Fields

top_left: Point

Top-left point of the bounding-box of the circle supporting the arc

diameter: u32

Diameter of the circle supporting the arc

angle_start: Angle

Angle at which the arc starts

angle_sweep: Angle

Angle defining the arc sweep starting at angle_start

Implementations

Create a new arc delimited with a top-left point with a specific diameter and start and sweep angles

Create a new arc centered around a given point with a specific diameter and start and sweep angles

Creates an arc based on a circle.

The resulting arc will match the top_left and diameter of the base circle.

Returns a circle with the same top_left and diameter as this arc.

Return the center point of the arc.

arc.translate_mut(Point::new(10, 10));

assert_eq!(arc.top_left, Point::new(15, 20));
