Implementations

impl EncodedOrigin

pub const LAST: Self = EncodedOrigin::LeftBottom

pub const DEFAULT: Self = EncodedOrigin::TopLeft

pub fn to_matrix(self, size: impl Into<ISize>) -> Matrix

Given an width and height of the source data, returns a matrix that transforms the source rectangle with upper left corner at [0, 0] and origin to a correctly oriented destination rectangle of [0, 0, w, h].

pub fn swaps_width_height(self) -> bool

Return true if the encoded origin includes a 90 degree rotation, in which case the width and height of the source data are swapped relative to a correctly oriented destination.

Trait Implementations

impl Clone for EncodedOrigin

fn clone(&self) -> EncodedOrigin

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EncodedOrigin

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

Formats the value using the given formatter.

impl Default for EncodedOrigin

fn default() -> EncodedOrigin

Returns the “default value” for a type.

impl Hash for EncodedOrigin

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<EncodedOrigin> for EncodedOrigin

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

This method tests for self and other values to be equal, and is used by ==.

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

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