Methods

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: u8) -> 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.
