Implementations§

impl RGBA

pub fn from_floats(red: f32, green: f32, blue: f32, alpha: f32) -> Self

Constructs a new RGBA value from float components. It expects the red, green, blue and alpha channels in that order, and all values will be clamped to the 0.0 … 1.0 range.

pub fn transparent() -> Self

Returns a transparent color.

pub fn new(red: u8, green: u8, blue: u8, alpha: f32) -> Self

Same thing, but with u8 values instead of floats in the 0 to 1 range.

pub fn red_f32(&self) -> f32

Returns the red channel in a floating point number form, from 0 to 1.

pub fn green_f32(&self) -> f32

Returns the green channel in a floating point number form, from 0 to 1.

pub fn blue_f32(&self) -> f32

Returns the blue channel in a floating point number form, from 0 to 1.

pub fn alpha_f32(&self) -> f32

Returns the alpha channel in a floating point number form, from 0 to 1.
