Struct exr::math::Vec2

pub struct Vec2<T>(pub T, pub T);

Simple two-dimensional vector of any numerical type. Supports only few mathematical operations as this is used mainly as data struct.

Implementations

impl<T> Vec2<T>

pub fn max(self, other: Self) -> Self where
    T: Ord, 

Returns the vector with the maximum of either coordinates.

pub fn min(self, other: Self) -> Self where
    T: Ord, 

Returns the vector with the minimum of either coordinates.

pub fn try_from<S>(value: Vec2<S>) -> Result<Self, T::Error> where
    T: TryFrom<S>, 

Try to convert all components of this vector to a new type, yielding either a vector of that new type, or an error.

pub fn area(self) -> T where
    T: Mul<T, Output = T>, 

Seeing this vector as a dimension or size (width and height), this returns the area that this dimensions contains (width * height).

pub fn x(self) -> T

The first component of this 2D vector.

pub fn y(self) -> T

The second component of this 2D vector.

pub fn width(self) -> T

The first component of this 2D vector.

pub fn height(self) -> T

The second component of this 2D vector.

pub fn flat_index_for_size(self, resolution: Vec2<T>) -> T where
    T: Copy + Debug + Ord + Mul<Output = T> + Add<Output = T>, 

Convert this two-dimensional coordinate to an index suited for one-dimensional flattened image arrays. Works for images that store the pixels row by row, one after another, in a single array. In debug mode, panics for an index out of bounds.

impl Vec2<i32>

pub fn to_usize(self, error_message: &'static str) -> Result<Vec2<usize>>

Try to convert to Vec2<usize>, returning an error on negative numbers.

impl Vec2<usize>

pub fn to_i32(self) -> Vec2<i32>

Panics for too large values
