Implementations

impl Rgbe8Pixel

pub fn to_hdr(self) -> Rgb<f32>

Converts Rgbe8Pixel into Rgb<f32> linearly

pub fn to_ldr<T: Primitive + Zero>(self) -> Rgb<T>

Converts Rgbe8Pixel into Rgb<T> with scale=1 and gamma=2.2

color_ldr = (color_hdr*scale)^gamma

Panic

Panics when T::max_value() cannot be represented as f32.

pub fn to_ldr_scale_gamma<T: Primitive + Zero>( self, scale: f32, gamma: f32 ) -> Rgb<T>

Converts Rgbe8Pixel into Rgb<T> using provided scale and gamma

color_ldr = (color_hdr*scale)^gamma

Panic

Panics when T::max_value() cannot be represented as f32. Panics when scale or gamma is NaN

Trait Implementations

impl Clone for Rgbe8Pixel

fn clone(&self) -> Rgbe8Pixel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rgbe8Pixel

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

Formats the value using the given formatter.

impl Default for Rgbe8Pixel

fn default() -> Rgbe8Pixel

Returns the “default value” for a type.

impl PartialEq<Rgbe8Pixel> for Rgbe8Pixel

fn eq(&self, other: &Rgbe8Pixel) -> 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.
