Struct Color 

pub struct Color { /* private fields */ }

A color in floating-point RGBA format in the range 0.0..=1.0, non-premultiplied alpha.

Implementations

impl Color

pub const TRANSPARENT: Color

pub const BLACK: Color

pub const WHITE: Color

pub fn from_rgba(r: f32, g: f32, b: f32, a: f32) -> Color

Creates a color from floating-point components (values are clamped to 0..=1).

pub fn from_rgba8(r: u8, g: u8, b: u8, a: u8) -> Color

Creates a color from 8-bit components.

pub fn red(&self) -> f32

pub fn green(&self) -> f32

pub fn blue(&self) -> f32

pub fn alpha(&self) -> f32

pub fn is_opaque(&self) -> bool

Whether the color is fully opaque.

pub fn set_alpha(&mut self, a: f32)

Sets the alpha (clamped to 0..=1).

pub fn premultiply(&self) -> PremultipliedColor

Converts to a premultiplied floating-point color.

pub fn to_color_u8(&self) -> ColorU8

Converts to an 8-bit non-premultiplied color.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Color

impl Debug for Color

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

Formats the value using the given formatter.

impl PartialEq for Color

fn eq(&self, other: &Color) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for Color

impl Tweenable for Color

fn lerp(a: &Self, b: &Self, t: f32) -> Self

Linear interpolation from a to b by the parameter t (0..=1).
