[−][src]Struct geopattern::color::Color

pub struct Color { /* fields omitted */ }

Color is a single color object

Methods

impl Color[src]

pub fn new(r: f64, g: f64, b: f64) -> Color[src]

create new colors

pub fn new_hcl(h: f64, c: f64, l: f64) -> Color[src]

create new colors from hcl color space

pub fn hex(s: &str) -> Result<Color, ColorError>[src]

convert a hex string ("#abc", "#fedcba") into a Color object

pub fn rgb(&self) -> (f64, f64, f64)[src]

get r, g, b for this object

pub fn almost_equal(&self, other: &Self) -> bool[src]

check if two colors are almost same

this means that the total difference is less than 3 * DELTA

pub fn linear_rgb(&self) -> (f64, f64, f64)[src]

linear RGB representation for the color

pub fn xyz(&self) -> (f64, f64, f64)[src]

XYZ representation for the color
