Implementations

source

impl PremultipliedColorU8

source

pub const TRANSPARENT: Self = PremultipliedColorU8::from_rgba_unchecked(0, 0, 0, 0)

A transparent color.

source

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

Creates a new premultiplied color.

RGB components must be <= alpha.

source

pub const fn red(self) -> u8

Returns color’s red component.

The value is <= alpha.

source

pub const fn green(self) -> u8

Returns color’s green component.

The value is <= alpha.

source

pub const fn blue(self) -> u8

Returns color’s blue component.

The value is <= alpha.

source

pub const fn alpha(self) -> u8

Returns color’s alpha component.

source

pub fn is_opaque(&self) -> bool

Check that color is opaque.

Alpha == 255

source

pub const fn get(self) -> u32

Returns the value as a primitive type.

source

pub fn demultiply(&self) -> ColorU8

Returns a demultiplied color.
