# Image Hasher

A fast image hash generator and hamming distance calculator using multiple algorithms

## Installation

```bash

npm install img-hasher

```

## Usage

### Get Hash Of an Image

```js

const { getHash } = require('img-hasher');

const hash = await getHash('https://example.com/image.jpg');

```

### Get Hash Distance Between Two Images

```js

const { hammingDistance } = require('img-hasher');

const distance = await hammingDistance('https://example.com/image1.jpg', 'https://example.com/image2.jpg');

```

### Get Hash Distance Between Two Hashes

```js

const { getHash, hammingDistanceFromHash } = require('img-hasher');

const hash1 = await getHash('https://example.com/image1.jpg');

const hash2 = await getHash('https://example.com/image2.jpg');

const distance = hammingDistanceFromHash(hash1, hash2);

```
