Struct RGBA

pub struct RGBA {
    pub red: u8,
    pub green: u8,
    pub blue: u8,
    pub alpha: u8,
}

Expand description

A color with red, green, blue, and alpha components, in a byte each.

Fields§

§red: u8

The red component.

§green: u8

The green component.

§blue: u8

The blue component.

§alpha: u8

The alpha component.

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.
