Struct rasterize::LinColor

pub struct LinColor(/* private fields */);

Alpha premultiplied RGBA color in the linear color space (no gamma correction)

Implementations

impl LinColor

pub fn new(r: f32, g: f32, b: f32, a: f32) -> Self

pub fn red(self) -> f32

pub fn green(self) -> f32

pub fn blue(self) -> f32

pub fn alpha(self) -> f32

pub fn distance(self, other: Self) -> f32

pub fn unmultiply(self) -> f32x4

Linear color is by default pre-multiplied by alpha, this function removes pre-multiplication.

Trait Implementations

impl Add for LinColor

type Output = LinColor

The resulting type after applying the + operator.

fn add(self, other: Self) -> Self::Output

Performs the + operation.

impl Clone for LinColor

fn clone(&self) -> LinColor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Color for LinColor

fn to_rgba(self) -> [u8; 4]

Convert color to sRGBA list

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

Blend other color on top of this color

fn with_alpha(self, alpha: Scalar) -> Self

Override alpha component of the color

fn lerp(self, other: Self, t: f32) -> Self

Linear interpolation between self and other colors.

fn to_rgb(self) -> [u8; 3]

Convert color to sRGB list (alpha is discarded)

fn luma(self) -> f32

Calculate LUMA of the color.

fn best_contrast(self, c0: Self, c1: Self) -> Self

Pick color that produces the best contrast with self

impl Debug for LinColor

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

Formats the value using the given formatter.

impl Default for LinColor

fn default() -> LinColor

Returns the “default value” for a type.

impl Display for LinColor

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

Formats the value using the given formatter.

impl From<LinColor> for [f32; 4]

fn from(color: LinColor) -> Self

Converts to this type from the input type.

impl From<LinColor> for RGBA

fn from(lin: LinColor) -> Self

Converts to this type from the input type.

impl From<RGBA> for LinColor

fn from(color: RGBA) -> Self

Converts to this type from the input type.

impl FromStr for LinColor

type Err = ColorError

The associated error which can be returned from parsing.

fn from_str(color: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Mul<f32> for LinColor

type Output = LinColor

The resulting type after applying the * operator.

fn mul(self, scale: f32) -> Self::Output

Performs the * operation.

impl Paint for LinColor

fn at(&self, _: Point) -> LinColor

fn units(&self) -> Option<Units>

fn transform(&self) -> Transform

impl PartialEq for LinColor

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