pub struct Orientation { /* private fields */ }
Expand description

An orientation of a geometric object.

Captures reflection and rotation, but not position or scaling.

Implementations§

source§

impl Orientation

source

pub fn from_reflect_and_angle(reflect_vert: bool, angle: f64) -> Self

Creates a new orientation with the given reflection and angle settings.

source

pub fn identity() -> Self

Returns the identity orientation with reflect_vert = false and angle = 0..

source

pub fn apply(self, o: impl Into<Orientation>) -> Self

Applies the reflection and rotation specified in Orientation o to this orientation.

source

pub fn reflected_vert(self) -> Self

Reflects the orientation vertically.

source

pub fn reflected_horiz(self) -> Self

Reflects the orientation horizontally.

source

pub fn r90(self) -> Self

Rotates the orientation 90 degrees counter-clockwise.

source

pub fn r180(self) -> Self

Rotates the orientation 180 degrees.

source

pub fn r270(self) -> Self

Rotates the orientation 180 degrees counter-clockwise.

source

pub fn r90cw(self) -> Self

Rotates the orientation 90 degrees clockwise.

source

pub fn r180cw(self) -> Self

Rotates the orientation 180 degrees clockwise.

source

pub fn r270cw(self) -> Self

Rotates the orientation 270 degrees clockwise.

source

pub fn flip_yx(self) -> Self

Flips the orientation around the line y = x.

source

pub fn flip_minus_yx(self) -> Self

Flips the orientation around the line y = -x.

source

pub fn reflect_vert(&self) -> bool

Returns whether the orientation is reflected vertically.

source

pub fn angle(&self) -> f64

Returns the angle associated with this orientation.

source

pub fn approx_eq(&self, other: &Self) -> bool

Compares the two orientations for approximate equality.

source

pub fn from_transformation(value: Transformation) -> Self

Returns the orientation represented by the given transformation.

Captures the rotation and reflection encoded by the Transformation, discarding the transformation’s translation.

§Example
let tf = Transformation::identity();
assert_eq!(Orientation::from_transformation(tf), NamedOrientation::R0.into());
source

pub fn all_rectangular() -> [Self; 8]

Returns a slice of all 8 possible rectangular orientations.

Users should not rely upon the order of the orientations returned.
