blurhash-fast

使用rayon实现，对Blurhash进行纯Rust实现，以实现更好的性能。

$ cargo add blurhash-fast

Blurhash是一种将图像编码为短字符串的算法。当您将字符串解码回图像时，您将获得代表原始图像的颜色渐变。

编码

use blurhash::encode;
use image::GenericImageView;

fn main() {
  let img = image::open("image.png").unwrap();

  let (width, height) = img.dimensions();

  let blurhash =
      encode(
          4, 3,
          width, height,
          &img.to_rgba8(),
      );
}

解码

use blurhash::decode;

let pixels =
    decode(
        "LBAdAqof00WCqZj[PDay0.WB}pof",
        50,
        50,
        1.0,
    );

注意

此项目基于 blurhash-rs。
