Struct PremultipliedColorU8 

pub struct PremultipliedColorU8(/* private fields */);

A 32-bit premultiplied RGBA color value.

Byteorder: RGBA (relevant for bytemuck casts)

Implementations

impl PremultipliedColorU8

pub const TRANSPARENT: Self

A transparent color.

pub fn from_rgba(r: u8, g: u8, b: u8, a: u8) -> Option<Self>

Creates a new premultiplied color.

RGB components must be <= alpha.

pub const fn red(self) -> u8

Returns color’s red component.

The value is <= alpha.

pub const fn green(self) -> u8

Returns color’s green component.

The value is <= alpha.

pub const fn blue(self) -> u8

Returns color’s blue component.

The value is <= alpha.

pub const fn alpha(self) -> u8

Returns color’s alpha component.

pub fn is_opaque(&self) -> bool

Check that color is opaque.

Alpha == 255

pub fn demultiply(&self) -> ColorU8

Returns a demultiplied color.

Trait Implementations

impl PartialEq for PremultipliedColorU8

fn eq(&self, other: &PremultipliedColorU8) -> 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.
