Implementations§

impl Color

pub const BLACK: Color

The black color.

pub const WHITE: Color

The white color.

pub const TRANSPARENT: Color

A color with no opacity.

pub const fn from_rgb(r: f32, g: f32, b: f32) -> Color

Creates a Color from its RGB components.

pub const fn from_rgba(r: f32, g: f32, b: f32, a: f32) -> Color

Creates a Color from its RGBA components.

pub const fn from_rgb8(r: u8, g: u8, b: u8) -> Color

Creates a Color from its RGB8 components.

pub const fn from_rgba8(r: u8, g: u8, b: u8, a: f32) -> Color

Creates a Color from its RGB8 components and an alpha value.

pub fn from_linear_rgba(r: f32, g: f32, b: f32, a: f32) -> Color

Creates a Color from its linear RGBA components.

pub fn parse(s: &str) -> Option<Color>

Parses a Color from a hex string.

Supported formats are #rrggbb, #rrggbbaa, #rgb, and #rgba. The starting “#” is optional. Both uppercase and lowercase are supported.

If you have a static color string, using the color! macro should be preferred since it leverages hexadecimal literal notation and arithmetic directly.

pub fn into_rgba8(self) -> [u8; 4]

Converts the Color into its RGBA8 equivalent.

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

Converts the Color into its linear values.

pub fn invert(&mut self)

Inverts the Color in-place.

pub fn inverse(self) -> Color

Returns the inverted Color.

pub fn scale_alpha(self, factor: f32) -> Color

Scales the alpha channel of the Color by the given factor.
