Struct tiny_skia :: color :: PremultipliedColorU8 Copy item path

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(crate) const fn from_rgba_unchecked(r: u8, g: u8, b: u8, a: u8) -> Self

Creates a new color.

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.
