-Who uses BlurHash? Here are some projects we know about:

-* [Wolt](http://wolt.com/) - We are of course using it ourselves. BlurHashes are used in the mobile clients on iOS and Android, as well as on the web, as placeholders during image loading.

 Technically, what it does is scale the AC components up or down.

-### Is this only useful as an image loading placeholder?
-
-Well, that is what it was designed for originally, but it turns out to be useful for a few other things:
-
-* Masking images without having to use expensive blurs - [Mastodon](http://github.com/tootsuite/mastodon) uses it for this.
-* The data representation makes it quite easy to extract colour averages of the image for different areas. You can easily find approximations of things like the average colour of the top edge of the image, or of a corner. There is some code in the Swift BlurHashKit implementation to experiment with this. Also, the average colour of the entire image is just the DC component and can be decoded even without implementing any of the more complicated DCT stuff.
-* We have been meaning to try to implement tinted drop shadows for UI elements by using the BlurHash and extending the borders. Haven't actually had time to implement this yet though.

-# blurhash
-
-[![NPM Version](https://img.shields.io/npm/v/blurhash.svg?style=flat)](https://npmjs.org/package/blurhash)
-[![NPM Downloads](https://img.shields.io/npm/dm/blurhash.svg?style=flat)](https://npmjs.org/package/blurhash)
-
-> JavaScript encoder and decoder for the [Wolt BlurHash](https://github.com/woltapp/blurhash) algorithm
-
-## Install
-
-```sh
-npm install --save blurhash
-```
-
-See [react-blurhash](https://github.com/woltapp/react-blurhash) to use blurhash with React.
-
-## API
-
-### `decode(blurhash: string, width: number, height: number, punch?: number) => Uint8ClampedArray`
-
-> Decodes a blurhash string to pixels
-
-#### Example
-
-```js
-import { decode } from "blurhash";
-
-const pixels = decode("LEHV6nWB2yk8pyo0adR*.7kCMdnj", 32, 32);
-
-const canvas = document.createElement("canvas");
-const ctx = canvas.getContext("2d");
-const imageData = ctx.createImageData(width, height);
-imageData.data.set(pixels);
-ctx.putImageData(imageData, 0, 0);
-document.body.append(canvas);
-```
-
-### `encode(pixels: Uint8ClampedArray, width: number, height: number, componentX: number, componentY: number) => string`
-
-> Encodes pixels to a blurhash string
-
-```js
-import { encode } from "blurhash";
-
-const loadImage = async src =>
-  new Promise((resolve, reject) => {
-    const img = new Image();
-    img.onload = () => resolve(img);
-    img.onerror = (...args) => reject(args);
-    img.src = src;
-  });
-
-const getImageData = image => {
-  const canvas = document.createElement("canvas");
-  canvas.width = image.width;
-  canvas.height = image.height;
-  const context = canvas.getContext("2d");
-  context.drawImage(image, 0, 0);
-  return context.getImageData(0, 0, image.width, image.height);
-};
-
-const encodeImageToBlurhash = async imageUrl => {
-  const image = await loadImage(imageUrl);
-  const imageData = getImageData(image);
-  return encode(imageData.data, imageData.width, imageData.height, 4, 4);
-};
-```
-
-### `isBlurhashValid(blurhash: string) => { result: boolean; errorReason?: string }`
-
-```js
-import { isBlurhashValid } from "blurhash";
-
-const validRes = isBlurhashValid("LEHV6nWB2yk8pyo0adR*.7kCMdnj");
-// { result: true }
-
-const invalidRes = isBlurhashValid("???");
-// { result: false, errorReason: "The blurhash string must be at least 6 characters" }
-```
