Generate color palettes from pixels or images using the mediancut algorithm.
Include iris-lib in your Cargo.toml:
iris-lib = "0.1.0"Create palettes from pixels:
use iris_lib::color_bucket::ColorBucket;
use iris_lib::color::Color;
fn main() {
let colors = vec![
Color { r: 255, g: 0, b: 0, a: 0 },
Color { r: 0, g: 255, b: 0, a: 0 },
Color { r: 0, g: 0, b: 255, a: 0 }
];
if let Some(mut bucket) = ColorBucket::from_pixels(colors) {
let palette = bucket.make_palette(3); // three iterations
println!("{:?}", palette);
};
}Result:
[Color { r: 255, g: 0, b: 0, a: 0 },
Color { r: 0, g: 255, b: 0, a: 0 },
Color { r: 0, g: 0, b: 255, a: 0 }]Include the image feature in your Cargo.toml reference.
iris-lib = { version = "0.1.0", features = ["image"]}Create palettes by passing the path of the target image:
use iris_lib::color_bucket::ColorBucket;
fn main() {
if let Some(mut bucket) = ColorBucket::from_image("peppers.png") {
let palette = bucket.make_palette(2); // two iterations
println!("{:?}", palette);
};
}Result:
[Color { r: 165, g: 197, b: 124, a: 255 },
Color { r: 144, g: 172, b: 74, a: 255 },
Color { r: 192, g: 51, b: 42, a: 255 },
Color { r: 97, g: 42, b: 25, a: 255 }]Check out iris the command line tool built on top of this library.
