+# BlurHash Algorithm
+
+## Summary
+
+BlurHash applies a simple [DCT transform](https://en.wikipedia.org/wiki/Discrete_cosine_transform) to the image data,
+keeping only the first few components, and then encodes these components using a base 83 encoding, with a JSON,
+HTML and shell-safe character set. The DC component, which represents the average colour of the image, is stored exactly
+as an sRGB value, for easy use without impleneting the full algorithm. The AC components are encoded lossily.
+
+## Reference implementation
+
+[Simplified Swift decoder implemenation.](Swift/BlurHashDecode.swift)
+
+[Simplified Swift encoder implemenation.](Swift/BlurHashEncode.swift)
+
+## Structure
+
+Here follows an example of a BlurHash string, with the different parts labelled:
+
+    Example: LlMF%n00%#MwS|WCWEM{R*bbWBbH
+    Legend:  12333344....................
+
+1. **Number of components, 1 digit.**
+   
+   For a BlurHash with `nx` components along the X axis and `ny` components along the Y axis, this is equal to `(nx - 1) + (ny - 1) * 9`.
+
+2. **Maximum AC component value, 1 digit.**
+   
+   All AC components are scaled by this value. It represents a floating-point value of `(max + 1) / 166`.
+
+3. **Average colour. 4 digits.**
+   
+   The average colour of the image in sRGB space, encoded as a 24-bit RGB value, with R in the most signficant position. This value can
+   be used directly if you only want the average colour rather than the full DCT-encoded image.
+
+4. **AC components, 2 digits each, `nx * ny - 1` components in total.**
+   
+   The AC components of the DCT transform, ordred by increasing X first, then Y. They  are encoded as three values for `R`, `G` and `B`,
+   each between 0 and 18. They are combined together as `R * 19^2 + G * 19 + B`, for a total range of 0 to 6859.
+   
+   Each value represents a floating-point value between -1 and 1. 0-8 represent negative values, 9 represents zero, and 10-18
+   represent positive values. Positive values are encoded as `((X - 9) / 9) ^ 2`, while negative
+   values are encoded as `-((9 - X) / 9 ) ^ 2`. `^` represents exponentiation. This value is then multiplied by the maximum AC
+   component value, field 2 above.
+
+## Base 83
+
+A custom base 83 encoding is used. Values are encoded individually, using 1 to 4 digits, and concatenated together. Multiple-digit
+values are encoded in big-endian order, with the most signficant digit first.
+
+The character used set is `0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz#$%*+,-.:;=?@[]^_{|}~`.
+
+## Discrete Cosine Transform
+
+To decode a single pixel of output, you loop over the DCT components and calculate a weighted sum of cosine functions. In
+pseudocode, for a normalised pixel position `x`, `y`, with each coordinate ranging from 0 to 1, and components `Cij` ,
+you calculate the following for each of R, G and B:
+
+    foreach j in 0 ... ny - 1
+        foreach i in 0 ... nx - 1
+            value = value + Cij * cos(x * i * pi) * cos(y * j * pi)
+
+The `C00` component is the DC component, while the others are the AC components. The DC component must first be converted
+from sRGB to linear RGB space. AC components are already linear.
+
+Once the R, G and B values have been calculated, the must be converted from linear to your output colourspace, usually sRGB.

+# BlurHash encoder in portable C
+
+This code implements an encoder for the BlurHash algorithm in C. It can be used to integrate into other language
+using an FFI interface. Currently the Python integration uses this code.
+
+## Usage as a library
+
+Include the `encode.c` and `encode.h` files in your project. They have no external dependencies.
+
+A single file function is defined:
+
+    const char *blurHashForPixels(int xComponents, int yComponents, int width, int height, uint8_t *rgb, size_t bytesPerRow) {
+
+This function returns a string containing the BlurHash. This memory is managed by the function, and you should not free it.
+It will be overwritten on the next call into the function, so be careful!
+
+* `xComponents` - The number of components in the X direction. Must be between 1 and 9. 3 to 5 is usually a good range for this.
+* `yComponents` - The number of components in the Y direction. Must be between 1 and 9. 3 to 5 is usually a good range for this.
+* `width` - The width in pixels of the supplied image.
+* `height` - The height in pixels of the supplied image.
+* `rgb` - A pointer to the pixel data. This is supplied in RGB order, with 3 bytes per pixels.
+* `bytesPerRow` - The number of bytes per row of the RGB pixel data.
+
+## Usage as a command-line tool
+
+You can also build a command-line version to test the encoder. However, note that it uses `stb_image` to load images,
+which is not really security-hardened, so it is **not** recommended to use this version in production on untrusted data!
+Use one of the integrations instead, which use more robust image loading libraries.
+
+Nevertheless, if you want to try it out quickly, simply run:
+
+	$ make
+	$ ./blurhash 4 3 ../Swift/BlurHashTest/pic1.png

+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at dag.agren@wolt.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+# [BlurHash](http://blurha.sh)
+
+BlurHash is a compact representation of a placeholder for an image.
+
+## Why would you want this?
+
+Does your designer cry every time you load their beautifully designed screen, and it is full of empty boxes because all the
+images have not loaded yet? Does your database engineer cry when you want to solve this by trying to cram little thumbnail
+images into your data to show as placeholders?
+
+BlurHash will solve your problems! How? Like this:
+
+<img src="Media/WhyBlurHash.png" width="600">
+
+You can also see nice examples and try it out yourself at [blurha.sh](http://blurha.sh/)!
+
+## How does it work?
+
+In short, BlurHash takes an image, and gives you a short string (only 20-30 characters!) that represents the placeholder for this
+image. You do this on the backend of your service, and store the string along with the image. When you send data to your
+client, you send both the URL to the image, and the BlurHash string. Your client then takes the string, and decodes it into an
+image that it shows while the real image is loading over the network. The string is short enough that it comfortably fits into
+whatever data format you use. For instance, it can easily be added as a field in a JSON object.
+
+In summary:

+<img src="Media/HowItWorks1.jpg" width="250">&nbsp;&nbsp;&nbsp;<img src="Media/HowItWorks2.jpg" width="250">
+
+Want to know all the gory technical details? Read the [algorithm description](Algorithm.md).
+
+Implementing the algorithm is actually quite easy! Implementations are short and easily ported to your favourite language or
+platform.
+
+## Implementations
+
+So far, we have created these implementations:
+
+* [C](C) - An encoder implemenation in portable C code.
+* [Swift](Swift) - Encoder and decoder implementations, and a larger library offering advanced features.
+  There is also an example app to play around with the algorithm.
+* [Kotlin](Kotlin) - A decoder implementation for Android.
+* [TypeScript](TypeScript) - Encoder and decoder implementations, and an example page to test.
+* [Python](https://github.com/woltapp/blurhash-python) - Integration of the C encoder code into Python.
+
+These cover our use cases, but could probably use polishing, extending and improving. There are also these third party implementations that we know of:
+
+* [Pure Python](https://github.com/halcy/blurhash-python) - Implementation of both the encoder and decoder in pure Python.
+* [One version in Go](https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=2ahUKEwjJ9ueT9pXjAhXRw6YKHfrGBNcQFjAAegQIABAB&url=https%3A%2F%2Fgithub.com%2Fbbrks%2Fgo-blurhash&usg=AOvVaw2alZSHvT7HbublYbpNn9fY), and [another version in Go](https://github.com/buckket/go-blurhash).
+* [PHP](https://github.com/kornrunner/php-blurhash) - Encoder and decoder implementations in pure PHP.
+* [Java](https://github.com/hsch/blurhash-java) - Encoder implementation in Java.
+* [Clojure](https://github.com/siili-core/blurhash) - Encoder and decoder implementations in Clojure.
+* [Nim](https://github.com/SolitudeSF/blurhash) - Encoder and decoder implementation in pure Nim.
+* [Rust and WebAssembly](https://github.com/fpapado/blurhash-rust-wasm) - Encoder and decoder implementations in Rust. Distributed as both native Rust and WebAssembly packages.
+
+Perhaps you'd like to help extend this list? Which brings us to...
+
+## Contributing
+
+We'd love contributions! The algorithm is [very simple](Algorithm.md) - less than two hundred lines of code - and can easily be
+ported to your platform of choice. And having support for more platforms would be wonderful! So, Java decoder? Golang encoder?
+Haskell? Rust? We want them all!
+
+We will also try to tag any issues on our [issue tracker](https://github.com/woltapp/blurhash/issues) that we'd love help with, so
+if you just want to dip in, go have a look.
+
+You can file a pull request with us, or you can start your own repo and project if you want to run everything yourself, we don't mind.
+
+If you do want to contribute to this project, we have a [code of conduct](CodeOfConduct.md).
+
+## Users
+
+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.
+* [Mastodon](https://github.com/tootsuite/mastodon) - The Mastodon decentralised social media network uses BlurHashes both as loading placeholders, as well as for hiding media marked as sensitive.
+
+## Good Questions
+
+### How fast is encoding? Decoding?
+
+These implementations are not very optimised. Running them on very large images can be a bit slow. The performance of
+the encoder and decoder are about the same for the same input or output size, so decoding very large placeholders, especially
+on your UI thread, can also be a bit slow.
+
+However! The trick to using the algorithm efficiently is to not run it on full-sized data. The fine detail of an image is all thrown away,
+so you should scale your images down before running BlurHash on them. If you are creating thumbnails, run BlurHash on those
+instead of the full images.
+
+Similarly, when displaying the placeholders, very small images work very well when scaled up. We usually decode placeholders
+that are 32 or even 20 pixels wide, and then let the UI layer scale them up, which is indistinguishable from decoding them at full size.
+
+### How do I pick the number of X and Y components?
+
+It depends a bit on taste. The more components you pick, the more information is retained in the placeholder, but the longer
+the BlurHash string will be. Also, it doesn't always look good with too many components. We usually go with 4 by 3, which
+seems to strike a nice balance.
+
+However, you should adjust the number of components depending on the aspect ratio of your images. For instance, very wide
+images should have more X components and fewer Y components.
+
+The Swift example project contains a test app where you can play around with the parameters and see the results.
+
+### What is the `punch` parameter in some of these implementations?
+
+It is a parameter that adjusts the contrast on the decoded image. 1 means normal, smaller values will make the effect more subtle,
+and larger values will make it stronger. This is basically a design parameter, which lets you adjust the look.
+
+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.
+
+### Why base 83?
+
+First, 83 seems to be about how many low-ASCII characters you can find that are safe for use in all of JSON, HTML and shells.
+
+Secondly, 83 * 83 is very close to, and a little more than, 19 * 19 * 19, making it ideal for encoding three AC components in two
+characters.
+
+### What about using the full Unicode character set to get a more efficient encoding?
+
+We haven't looked into how much overehead UTF-8 encoding would introduce versus base 83 in single-byte characters, but
+the encoding and decoding would probably be a lot more complicated, so in the spirit of minimalism BlurHash uses the simpler
+option. It might also be awkward to copy-paste, depending on OS capabilities.
+
+If you think it can be done and is worth it, though, do make your own version and show us! We'd love to see it in action.
+
+### What about other basis representations than DCT?
+
+This is something we'd *love* to try. The DCT looks quite ugly when you increase the number of components, probably because
+the shape of the basis functions becomes too visible. Using a different basis with more aesthetically pleasing shape might be
+a big win.
+
+However, we have not managed come up with one. Some experimenting with a [Fourier-Bessel base](https://en.wikipedia.org/wiki/Fourier–Bessel_series),
+targeted at images that are going to be cropped into circles has been done, but without much success. Here again we'd love
+to see what you can come up with!

+# BlurHash for iOS, in Swift
+
+## Standalone decoder and encoder
+
+[BlurHashDecode.swift](BlurHashDecode.swift) and [BlurHashEncode.swift](BlurHashEncode.swift) contain a decoder
+and encoder for BlurHash to and from `UIImage`. Both files are completeiy standalone, and can simply be copied into your
+project directly.
+
+### Decoding
+
+[BlurHashDecode.swift](BlurHashDecode.swift) implements the following extension on `UIImage`:
+
+	public convenience init?(blurHash: String, size: CGSize, punch: Float = 1)
+
+This creates a UIImage containing the placeholder image decoded from the BlurHash string, or returns nil if decoding failed.
+The parameters are:
+
+* `blurHash` - A string containing the BlurHash.
+* `size` - The requested output size. You should keep this small, and let UIKit scale it up for you. 32 pixels wide is plenty.
+* `punch` - Adjusts the contrast of the output image. Tweak it if you want a different look for your placeholders.
+
+### Encoding
+
+ [BlurHashEncode.swift](BlurHashEncode.swift) implements the following extension on `UIImage`:
+
+	public func blurHash(numberOfComponents components: (Int, Int)) -> String?
+
+This returns a string containing the BlurHash for the image, or nil if the image was in a weird format that is not supported.
+The parameters are:
+
+* `numberOfComponents` - a Tuple of integers specifying the number of components in the X and Y directions. Both must be
+between 1 and 9 inclusive, or the function will return nil.  3 to 5 is usually a good range.
+
+## BlurHashKit
+
+This is a more advanced library, currently in development. It will let you do more advanced operations using BlurHashes,
+such testing whether various parts of an image are dark and light, or generating BlurHashes as gradients from corner colours.
+
+It is currently not documented or finalised, but feel free to look into the different files and what they implement, or look at
+how it is used by the test app.
+
+## BlurHashTest.app
+
+This is a simple test app that shows how to use the various pieces of BlurHash functionality, and lets you play with the
+algorithm.

+
+> 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" }
+```
