Implementations

impl SrgbRgba

pub fn zero() -> Self

pub fn one() -> Self

pub const fn from_f32(r: f32, g: f32, b: f32, a: f32) -> Self

pub fn from_unorm8(r: Unorm8, g: Unorm8, b: Unorm8, a: Unorm8) -> Self

pub fn from_u8(r: u8, g: u8, b: u8, a: u8) -> Self

pub const fn from_f32_array(color: [f32; 4]) -> Self

pub fn from_unorm8_array(color: [Unorm8; 4]) -> Self

pub fn from_u8_array(color: [u8; 4]) -> Self

pub const fn into_f32_array(self) -> [f32; 4]

pub fn into_unorm8_array(self) -> [Unorm8; 4]

pub fn into_u8_array(self) -> [u8; 4]

pub fn a(self, alpha: f32) -> Self

Change the alpha channel.

Note that alpha is always pre-multiplied, meaning the RGB channels will be multiplied by this new alpha value. Therefore, calling this more than once may be destructive.

This internally converts to linear color and back, so if you're going to convert to linear as a final step anyway, you should call this after that.

pub fn pma(self) -> Self

Convert to pre-multiplied alpha. This should only be called when consuming data that isn't pre-multiplied.

pub fn to_linear(self) -> LinRgba
