kkhash

Usage

``
import {kkHash,getBuffer} from 'kkhash';

const run = async()=>{
// get local picture's buffer;
const buffer = await getBuffer('./.jpg'); // or getBuffer('./.jpg','local')
// get buffer from internet
const buffer = await getBuffer('https://www.xxx.com/xx.jpg','http');

const aHash = await kkHash.getAHash(buffer);
console.log(aHash,aHash) // eg:0010010001100110010011000110011001001100010001000100000101100110
const pHash = await kkHash.getPHash(buffer);
const dHash = await kkHash.getDHash(buffer);
const contHash = await kkHash.getContHash(buffer)
}

run().catch(err=>console.log(err)); // you can use try/catch in your own code

`

if you don't want to use getBuffer :

`
import {readFileSync} from 'fs';
import axios from 'axios'
import {kkHash} from 'kkhash';

const run = async()=>{
const buffer = readFileSync('./**.jpg);
// or
const res = await axios.get(https://www.xxx.com/xx.jpg, { responseType: arraybuffer })
const buffer = res.data as Buffer
const aHash = await kkHash.getAHash(buffer);
const pHash = await kkHash.getPHash(buffer);
const dHash = await kkHash.getDHash(buffer);
const contHash = await kkHash.getContHash(buffer)
console.log(contHash,contHash)
// eg : 0010010001100110010011000110011001001100010001000100000101100110
}

run().catch(err=>console.log(err))
`

and if you want to compare two picture hash:

`
import {kkHash,getBuffer,catchSimilarity} from 'kkhash';

const run = async()=>{
// get buffer from local
const buffer = await getBuffer('./.jpg'); // or getBuffer('./.jpg','local');
// get buffer from internet
const buffer2 = await getBuffer('https://www.xxx.com/xx.jpg','http');

const aHash1 = await kkHash.getAHash(buffer1);
const aHash2 = await kkHash.getAHash(buffer2);
const similarity = catchSimilarity(aHash1,aHash2);
console.log(similarity,similarity); // eg: 93.45
// to use " getPHash getDHash getContHash " is like to use aHash
}

run().catch(err=>console.log(err));

`

you can defined "size" :
`
const aHash = await getAHash(someBuffer,8) // or 16 32 64

this package is created for my self in my work ...
so , i will always chang or add some function , and if you installed this package,you have to remember the version you installed @.@
