Struct Annulus 

pub struct Annulus {
    pub center: PixelCoord,
    pub inner_radius: Scalar,
    pub outer_radius: Scalar,
}

A circular annulus (ring) in image coordinates.

Fields

center: PixelCoord

Center position.

inner_radius: Scalar

Inner radius in pixels.

outer_radius: Scalar

Outer radius in pixels.

Implementations

impl Annulus

pub fn new( center: PixelCoord, inner_radius: Scalar, outer_radius: Scalar, ) -> Self

Create a new annulus. Panics if inner_radius > outer_radius.

pub fn thickness(&self) -> Scalar

Radial thickness of the annulus.

pub fn mean_radius(&self) -> Scalar

Mean radius of the annulus.

Trait Implementations

impl Clone for Annulus

fn clone(&self) -> Annulus

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Annulus

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Annulus

fn eq(&self, other: &Annulus) -> bool

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

fn ne(&self, other: &Rhs) -> bool

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

impl Copy for Annulus
