# ico2pngs

Extract the bitmaps from a `.ico` file and convert them to `.png` files. 

## Highlights

- Converts each image in the `.ico` file into `.png` data

- Returns png data in a buffer, width, height & bits per pixel

- Works in Node.js and in a browser

## Install 

```sh

npm install @johnls/ico2pngs

```

## Usage

In Node.js:

```js

import { ico2pngs } from "ico2pngs"

import fsPromise from "fs/promises"

;(async function () {

  var buf = await fsPromise.readFile("test/favicon.ico")

  var pngs = ico2pngs(buf.buffer)

  console.log(

    `width: ${pngs[0].width}, height: ${pngs[0].height}, bitsPerPixel: ${pngs[0].bitsPerPixel}`

  )

  await fsPromise.writeFile("scratch/favicon0.png", pngs[0].pngData)

})()

```
