Implementations

source

impl Rgbe8Pixel

source

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

Converts Rgbe8Pixel into Rgb<f32> linearly

source

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.

source

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

Converts Rgbe8Pixel into Rgb 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
