Struct xilem::Color

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

32-bit RGBA color.

Fields

r: u8

Red component.

g: u8

Green component.

b: u8

Blue component.

a: u8

Alpha component.

Implementations

impl Color

pub const fn rgb8(r: u8, g: u8, b: u8) -> Color

Creates a new RGB color with 255 alpha.

pub const fn rgba8(r: u8, g: u8, b: u8, a: u8) -> Color

Creates a new RGBA color.

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

Create a color from three floating point values, each in the range 0.0 to 1.0.

The interpretation is the same as rgb8, and no greater precision is (currently) assumed.

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

Create a color from four floating point values, each in the range 0.0 to 1.0.

The interpretation is the same as rgba32, and no greater precision is (currently) assumed.

pub fn hlc(h: f64, l: f64, c: f64) -> Color

Create a color from a CIEL*a*b* polar (also known as CIE HCL) specification.

The h parameter is an angle in degrees, with 0 roughly magenta, 90 roughly yellow, 180 roughly cyan, and 270 roughly blue. The l parameter is perceptual luminance, with 0 black and 100 white. The c parameter is a chrominance concentration, with 0 grayscale and a nominal maximum of 127 (in the future, higher values might be useful, for high gamut contexts).

Currently this is just converted into sRGB, but in the future as we support high-gamut colorspaces, it can be used to specify more colors or existing colors with a higher accuracy.

Currently out-of-gamut values are clipped to the nearest sRGB color, which is perhaps not ideal (the clipping might change the hue). See https://github.com/d3/d3-color/issues/33 for discussion.

pub fn hlca(h: f64, l: f64, c: f64, a: f64) -> Color

Create a color from a CIEL*a*b* polar specification and alpha.

The a value represents alpha in the range 0.0 to 1.0.

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

Parses a color from a string.

Currently accepts CSS style hexadecimal colors of the forms #RGB, #RGBA, #RRGGBB, #RRGGBBAA or the name of an SVG color such as “aliceblue”.

pub fn with_alpha_factor(self, alpha: f32) -> Color

Returns the color with the alpha component multiplied by the specified factor.

pub fn to_premul_u32(self) -> u32

Returns the color as a packed premultiplied value.
