Struct colors_transform::Rgb

pub struct Rgb { /* fields omitted */ }

Methods

impl Rgb

pub fn from(r: f32, g: f32, b: f32) -> Rgb

pub fn grayscale(&self, method: GrayScaleMethod) -> Rgb

pub fn from_hex_str(s: &str) -> Result<Rgb, ParseError>

Try to parse string as hex color

Example

use colors_transform::{Rgb,Color};

assert_eq!(Rgb::from_hex_str("#e76B2c").unwrap(),Rgb::from(231.0,107.0,44.0));
assert_eq!(Rgb::from_hex_str("fc0").unwrap(),Rgb::from_tuple(&(255.0,204.0,0.0)));
assert!(Rgb::from_hex_str("cyan").is_err());

pub fn to_css_hex_string(&self) -> String

Returns hexadecimal color string like in css. In lowercase with no reductions

Example

use colors_transform::{Rgb,Color};

let rgb1 = Rgb::from_tuple(&(231.0,107.0,44.0));
assert_eq!(rgb1.to_css_hex_string(),"#e76b2c");

let rgb2 = Rgb::from_hex_str("#0C7").unwrap();
assert_eq!(rgb2.to_css_hex_string(),"#00cc77");
