Struct Color 

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

👎Deprecated:

Use esoc_color::Color instead — this type uses sRGB f64, esoc_color uses linear f32

An RGBA color with f64 channels in [0.0, 1.0].

Deprecated: This type uses sRGB f64 values. Prefer esoc_color::Color which uses linear f32 RGBA (GPU-native). Use esoc_color::Color::from(legacy_color) to convert.

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

Create an opaque color from RGB channels in [0.0, 1.0].

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

Create a color from 8-bit RGB values.

pub fn from_hex(hex: &str) -> Result<Color, GfxError>

Parse a hex color string (#RRGGBB or #RRGGBBAA).

pub fn lerp(self, other: Color, t: f64) -> Color

Linearly interpolate between two colors.

pub fn with_alpha(self, a: f64) -> Color

Return this color with a new alpha value.

pub fn to_svg_string(self) -> String

pub fn to_hex(self) -> String

Format as a hex string (#RRGGBB).

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Color

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Color

fn default() -> Color

Returns the “default value” for a type.

impl From<Color> for Color

fn from(c: Color) -> Color

Convert from legacy sRGB f64 Color to linear f32 Color.

Applies sRGB→linear conversion on each channel.

impl From<Color> for Color

fn from(c: Color) -> Color

Convert from new linear f32 Color back to legacy sRGB f64 Color.

Applies linear→sRGB conversion on each channel.

impl PartialEq for Color

fn eq(&self, other: &Color) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Color

impl StructuralPartialEq for Color
