blurhash-wasm

A Rust implementation of the blurhash algorithm.

It is compiled to WebAssembly (WASM), and available on npm as blurhash-wasm.

Usage in JS

Installation

You will need a package manager, either npm (comes with node) or yarn.

You will also need a bundler, webpack or Rollup, configured for your project.

Then, in a terminal:

```shell npm install blurhash-wasm

Or, yarn add blurhash-wasm

```

The demo app source has a complete example of using blurhash-wasm.

decode

```js import * as blurhash from "blurhash-wasm";

// Returned as Uint8Array | undefined // You can use this to construct canvas-compatible resources const pixels = blurhash.decode("LKO2?U%2Tw=w]~RBVZRi};RPxuwH", 40, 30); ```

Usage in Rust

Installation

You will need Rust and Cargo.

Add the version you want to Cargo.toml:

[dependencies] blurhash-wasm = "0.1.0"

decode

```rust use blurhash_wasm;

// Result, blurhash::Error> let res = blurhash::decode("LKO2?U%2Tw=w]~RBVZRi};RPxuwH", 40, 30); ```

encode

About the setup

Based on the rust wasm-pack template

This template is designed for compiling Rust libraries into WebAssembly and publishing the resulting package to NPM.
