Struct Color 

pub struct Color {
    pub a: u8,
    pub r: u8,
    pub g: u8,
    pub b: u8,
}

An ARGB color.

Fields

a: u8

The Alpha component of the color.

r: u8

The Red component of the color.

g: u8

The Green component of the color.

b: u8

The Blue component of the color.

Implementations

impl Color

pub const fn new(a: u8, r: u8, g: u8, b: u8) -> Self

Initializes a new instance of the Color struct.

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

Creates a Color from alpha, red, green and blue components.

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

Creates an opaque Color from red, green and blue components.

pub const fn from_uint32(value: u32) -> Color

Creates a Color from an integer in 0xAARRGGBB layout.

pub fn parse(s: &str) -> Result<Color, FormatError>

Parses a color string: #rgb, #argb, #rrggbb, #aarrggbb, rgb()/rgba(), hsl()/hsla(), hsv()/hsva() or a known color name.

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

Parses a color string, returning None when it is not a valid color.

pub fn to_string_format( &self, format: Option<&str>, format_provider: Option<&CultureInfo>, ) -> Result<String, FormatError>

Returns the string representation of the color using a format specifier.

Supported format specifiers:

• X: XAML hex with alpha, #AARRGGBB
• x: hex without alpha, #RRGGBB
• H: HTML/CSS hex with alpha, #RRGGBBAA
• R / r: CSS rgba(r, g, b, a) / rgb(r, g, b)
• R% / r%: CSS rgba(r%, g%, b%, a%) / rgb(r%, g%, b%)
• L, l, L%, l%: converted to HSL and formatted as such
• V, v, V%, v%: converted to HSV and formatted as such

A null or empty format is the same as to_string(). Any other format is an error. format_provider is ignored: color formatting is culture-invariant.

pub const fn to_uint32(&self) -> u32

Returns the integer representation of the color in 0xAARRGGBB layout.

pub fn to_hsl(&self) -> HslColor

Returns the HSL color model equivalent of this RGB color.

pub fn to_hsv(&self) -> HsvColor

Returns the HSV color model equivalent of this RGB color.

pub const fn equals(&self, other: Color) -> bool

Check if two colors are equal.

pub fn rgb_to_hsl(red: u8, green: u8, blue: u8, alpha: u8) -> HslColor

Converts the given RGBA color component values to their HSL color equivalent.

pub fn normalized_rgb_to_hsl(r: f64, g: f64, b: f64, a: f64) -> HslColor

Converts the given RGBA color component values to their HSL color equivalent. Warning: no bounds checks or clamping is done on the input component values; they are assumed to be within the 0..1 range. The result is not clamped either.

pub fn rgb_to_hsv(red: u8, green: u8, blue: u8, alpha: u8) -> HsvColor

Converts the given RGBA color component values to their HSV color equivalent.

pub fn normalized_rgb_to_hsv(r: f64, g: f64, b: f64, a: f64) -> HsvColor

Converts the given RGBA color component values to their HSV color equivalent. Warning: no bounds checks or clamping is done on the input component values; they are assumed to be within the 0..1 range. The result is not clamped either.
