Struct palette::luma::Luma

#[repr(C)]
pub struct Luma<S = Srgb, T = f32> where
    T: Component,
    S: LumaStandard,  {
    pub luma: T,
    pub standard: PhantomData<S>,
}

Luminance.

Luma is a purely gray scale color space, which is included more for completeness than anything else, and represents how bright a color is perceived to be. It's basically the Y component of CIE XYZ. The lack of any form of hue representation limits the set of operations that can be performed on it.

Fields

luma: T

The lightness of the color. 0.0 is black and 1.0 is white.

standard: PhantomData<S>

The kind of RGB standard. sRGB is the default.

Methods

impl<S, T> Luma<S, T> where
    T: Component,
    S: LumaStandard, 

pub fn new(luma: T) -> Luma<S, T>

pub fn into_format<U: Component>(self) -> Luma<S, U>

Convert into another component type.

pub fn from_format<U: Component>(color: Luma<S, U>) -> Self

Convert from another component type.

pub fn into_components(self) -> (T,)

Convert to a (luma,) tuple.

pub fn from_components((luma): (T,)) -> Self

Convert from a (luma,) tuple.

impl<S, T> Luma<S, T> where
    T: Component + Float,
    S: LumaStandard, 

pub fn into_linear(self) -> Luma<Linear<S::WhitePoint>, T>

Convert the color to linear luminance.

pub fn from_linear(color: Luma<Linear<S::WhitePoint>, T>) -> Luma<S, T>

    self
) -> Luma<St, T>

Convert the color to a different encoding.

pub fn from_encoding<St: LumaStandard<WhitePoint = S::WhitePoint>>(
    color: Luma<St, T>
) -> Luma<S, T>

Trait Implementations

impl<S, T> Blend for Luma<S, T> where
    T: Component + Float,
    S: LumaStandard<TransferFn = LinearFn>, 

type Color = Luma<S, T>

The core color type. Typically Self for color types without alpha.

fn into_premultiplied(self) -> PreAlpha<Luma<S, T>, T>

Convert the color to premultiplied alpha.

fn from_premultiplied(color: PreAlpha<Luma<S, T>, T>) -> Self

Convert the color from premultiplied alpha.

fn blend<F>(self, destination: Self, blend_function: F) -> Self where
    F: BlendFunction<Self::Color>, 

Blend self, as the source color, with destination, using blend_function. Anything that implements BlendFunction is acceptable, including functions and closures.

fn over(self, other: Self) -> Self

Place self over other. This is the good old common alpha composition equation.

fn inside(self, other: Self) -> Self

Results in the parts of self that overlaps the visible parts of other.

fn outside(self, other: Self) -> Self

Results in the parts of self that lies outside the visible parts of other.

fn atop(self, other: Self) -> Self

Place self over only the visible parts of other.

fn xor(self, other: Self) -> Self

Results in either self or other, where they do not overlap.

fn plus(self, other: Self) -> Self

Add self and other. This uses the alpha component to regulate the effect, so it's not just plain component wise addition.

fn multiply(self, other: Self) -> Self

Multiply self with other. This uses the alpha component to regulate the effect, so it's not just plain component wise multiplication.

fn screen(self, other: Self) -> Self

Make a color which is at least as light as self or other.

fn overlay(self, other: Self) -> Self

Multiply self or other if other is dark, or screen them if other is light. This results in an S curve.

fn darken(self, other: Self) -> Self

Return the darkest parts of self and other.

fn lighten(self, other: Self) -> Self

Return the lightest parts of self and other.

fn dodge(self, other: Self) -> Self

Lighten other to reflect self. Results in other if self is black.

fn burn(self, other: Self) -> Self

Darken other to reflect self. Results in other if self is white.

fn hard_light(self, other: Self) -> Self

Multiply self or other if other is dark, or screen them if self is light. This is similar to overlay, but depends on self instead of other.

fn soft_light(self, other: Self) -> Self

Lighten other if self is light, or darken other as if it's burned if self is dark. The effect is increased if the components of self is further from 0.5.

fn difference(self, other: Self) -> Self

Return the absolute difference between self and other. It's basically abs(self - other), but regulated by the alpha component.

fn exclusion(self, other: Self) -> Self

Similar to difference, but appears to result in a lower contrast. other is inverted if self is white, and preserved if self is black.
