Struct Color

Source

pub struct Color {
    pub r: f64,
    pub g: f64,
    pub b: f64,
    pub a: f64,
}

Expand description

An RGBA color with components in the range 0.0 to 1.0.

This type is used for defining color scales. Colors are converted to 8-bit RGBA values during rendering.

Fields§

§r: f64

Red component (0.0 to 1.0)

§g: f64

Green component (0.0 to 1.0)

§b: f64

Blue component (0.0 to 1.0)

§a: f64

Alpha component (0.0 to 1.0)

Implementations§

Source §

impl Color

Source

pub const BLACK: Color

Black color.

Source

pub const WHITE: Color

White color.

Source

pub const TRANSPARENT: Color

Transparent (fully transparent black).

Source

pub const fn rgb(r: f64, g: f64, b: f64) -> Self

Creates a new color from RGB components (alpha defaults to 1.0).

Components should be in the range 0.0 to 1.0.

Source

pub const fn rgba(r: f64, g: f64, b: f64, a: f64) -> Self

Creates a new color from RGBA components.

Components should be in the range 0.0 to 1.0.

Source

pub fn to_rgba8(&self) -> [u8; 4]

Converts the color to 8-bit RGBA values.
