> Collection of metrics and encodings for the standard 14 PDF fonts
This project is a fork of [`afm`](https://github.com/chbrown/afm) and was created for use in [`pdf-lib`](https://github.com/Hopding/pdf-lib). This forks exists for two primary reasons:
1. The original project did not include mappings from Unicode to WinAnsi/ZapfDingbats/Symbol encodings.
2. The font metrics included in the original project were uncompressed (not ideal for usage in `pdf-lib`).
## Usage
```js
import { Font, FontNames, Encodings } from '@pdf-lib/standard-fonts';
const codePoint = '∑'.charCodeAt(0);
const glyph = Encodings.Symbol.encodeUnicodeCodePoint(codePoint);
glyph // => { code: 229, name: 'summation' }
const font = Font.load(FontNames.Symbol);
const width = font.getWidthOfGlyph(glyph.name);
width // => 713
```
## Installation
### NPM Module
To install the latest stable version:
```bash
# With npm
npm install --save @pdf-lib/standard-fonts
# With yarn
yarn add @pdf-lib/standard-fonts
```
This assumes you're using [npm](https://www.npmjs.com/) or [yarn](https://yarnpkg.com/lang/en/) as your package manager.
### UMD Module
You can also download `@pdf-lib/standard-fonts` as a UMD module from [unpkg](https://unpkg.com/#/). The UMD builds have been compiled to ES5, so they should work [in any modern browser](https://caniuse.com/#feat=es5). UMD builds are useful if you aren't using a package manager or module bundler. For example, you can use them directly in the `<script>` tag of an HTML page.
The following builds are available:
* https://unpkg.com/@pdf-lib/standard-fonts/dist/standard-fonts.js
* https://unpkg.com/@pdf-lib/standard-fonts/dist/standard-fonts.min.js
When using a UMD build, you will have access to a global `window.StandardFonts` variable. This variable contains the classes and enums exported by `@pdf-lib/standard-fonts`. For example:
```javascript
// NPM module
import { Font, FontNames, Encodings } from '@pdf-lib/standard-fonts';
const font = Font.load(FontNames.HelveticaBold);
const encoding = Encodings.WinAnsi;
// UMD module
var font = StandardFonts.Font.load(StandardFonts.FontNames.HelveticaBold);
var encoding = StandardFonts.Encodings.WinAnsi;
```

> A small, fast and advanced PNG / APNG encoder and decoder
This project is a fork of [`UPNG.js`](https://github.com/photopea/UPNG.js) and was created for use in [`pdf-lib`](https://github.com/Hopding/pdf-lib). The maintainer of the original repo does not publish it to NPM. That is the primary purpose of this fork. In addition, an `index.d.ts` file has been added (copied directly from [`@types/upng-js`](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/upng-js/index.d.ts)) to makes TypeScript definitions available without requiring additional packages to be installed.
## Example of `UPNG.toRGBA8`
```javascript
// Import the UPNG class
import UPNG from '@pdf-lib/upng';
// Create a UPNG object
const pngImage = UPNG.decode(/* Uint8Array containing bytes of PNG image */);
// `pixels` is a 1D array (in rgba order) of decoded pixel data
const pixels = pngImage.UPNG.toRGBA8();
```
## Installation
### NPM Module
To install the latest stable version:
```bash
# With npm
npm install --save @pdf-lib/upng
# With yarn
yarn add @pdf-lib/upng
```
This assumes you're using [npm](https://www.npmjs.com/) or [yarn](https://yarnpkg.com/lang/en/) as your package manager.
### UMD Module
You can also download `@pdf-lib/upng` as a UMD module from [unpkg](https://unpkg.com/#/). The UMD builds have been compiled to ES5, so they should work [in any modern browser](https://caniuse.com/#feat=es5). UMD builds are useful if you aren't using a package manager or module bundler. For example, you can use them directly in the `<script>` tag of an HTML page.
The following builds are available:
* https://unpkg.com/@pdf-lib/upng/dist/UPNG.js
* https://unpkg.com/@pdf-lib/upng/dist/UPNG.min.js
When using a UMD build, you will have access to a global `window.UPNG` variable. This variable contains the `UPNG` class exported by `@pdf-lib/upng`. For example:
```javascript
// NPM module
import UPNG from '@pdf-lib/upng';
const pngImage = UPNG.decode(/* ... */)
// UMD module
var pngImage = window.UPNG.decode(/* ... */)
```
## Encoder
UPNG.js supports APNG and the interface expects "frames". Regular PNG is just a single-frame animation (single-item array).
#### `UPNG.encode(imgs, w, h, cnum, [dels])`
* `imgs`: array of frames. A frame is an ArrayBuffer containing the pixel data (RGBA, 8 bits per channel)
* `w`, `h` : width and height of the image
* `cnum`: number of colors in the result; 0: all colors (lossless PNG)
* `dels`: array of millisecond delays for each frame (only when 2 or more frames)
* returns an ArrayBuffer with binary data of a PNG file
UPNG.js can do a lossy minification of PNG files, similar to [TinyPNG](https://tinypng.com/) and other tools. It performed quantization with [k-means algorithm](https://en.wikipedia.org/wiki/K-means_clustering) in the past, but now we use [K-d trees](https://en.wikipedia.org/wiki/K-d_tree).
Lossy compression is allowed by the last parameter `cnum`. Set it to zero for a lossless compression, or write the number of allowed colors in the image. Smaller values produce smaller files. **Or just use 0 for lossless / 256 for lossy.**
// Read RGBA from canvas and encode with UPNG
var dta = ctx.getImageData(0,0,200,300).data; // ctx is Context2D of a Canvas
// dta = new Uint8Array(200 * 300 * 4); // or generate pixels manually
var png = UPNG.encode([dta.buffer], 200, 300, 0); console.log(new Uint8Array(png));
#### `UPNG.encodeLL(imgs, w, h, cc, ac, depth, [dels])` - low-level encode
* `imgs`: array of frames. A frame is an ArrayBuffer containing the pixel data (corresponding to following parameters)
* `w`, `h` : width and height of the image
* `cc`, `ac`: number of color channels (1 or 3) and alpha channels (0 or 1)
* `depth`: bit depth of pixel data (1, 2, 4, 8, 16)
* `dels`: array of millisecond delays for each frame (only when 2 or more frames)
* returns an ArrayBuffer with binary data of a PNG file
This function does not do any optimizations, it just stores what you give it. There are two cases when it is useful:
* saving 16-bit colors (note, that PNG is big-endian, unlike Uint16Array in JS)
* your image is too large, and "expanding" to 8-bit RGBA would use too much memory (e.g. 4-bit grayscale 50,000 x 50,000 = 1.25 GB, 8-bit RGBA would be 10 GB)
## Decoder
Supports all color types (including Grayscale and Palettes), all channel depths (1, 2, 4, 8, 16), interlaced images etc. Opens PNGs which other libraries can not open (tested with [PngSuite](http://www.schaik.com/pngsuite/)).
#### `UPNG.decode(buffer)`
* `buffer`: ArrayBuffer containing the PNG file
* returns an image object with following properties:
* * `width`: the width of the image
* * `height`: the height of the image
* * `depth`: number of bits per channel
* * `ctype`: color type of the file (Truecolor, Grayscale, Palette ...)
* * `frames`: additional info about frames (frame delays etc.)
* * `tabs`: additional chunks of the PNG file
* * `data`: pixel data of the image
PNG files may have a various number of channels and a various color depth. The interpretation of `data` depends on the current color type and color depth (see the [PNG specification](https://www.w3.org/TR/PNG/)).
#### `UPNG.toRGBA8(img)`
* `img`: PNG image object (returned by UPNG.decode())
* returns an array of frames. A frame is ArrayBuffer of the image in RGBA format, 8 bits per channel.
### Example
var img = UPNG.decode(buff); // put ArrayBuffer of the PNG file into UPNG.decode
var rgba = UPNG.toRGBA8(img)[0]; // UPNG.toRGBA8 returns array of frames, size: width * height * 4 bytes.
PNG format uses the Inflate algorithm. Right now, UPNG.js calls [Pako.js](https://github.com/nodeca/pako) for the Inflate and Deflate method.
## Quantizer
UPNG.js contains a very good Quantizer of 4-component 8-bit vectors (i.e. pixels). It can be used to generate nice color palettes (e.g. Photopea uses UPNG.js to make palettes for GIF images).
Quantization consists of two important steps: Finding a nice palette and Finding the closest color in the palette for each sample (non-trivial for large palettes). UPNG perfroms both steps.
var res = UPNG.quantize(data, psize);
* `data`: ArrayBuffer of samples (byte length is a multiple of four)
* `psize` : Palette size (how many colors you want to have)
The result object "res" has following properties:
* `abuf`: ArrayBuffer corresponding to `data`, where colors are remapped by a palette
* `inds`: Uint8Array : the index of a color for each sample (only when `psize`<=256)
* `plte`: Array : the Palette - a list of colors, `plte[i].est.q` and `plte[i].est.rgba` is the color value
### FAQ
- To get one common palette for multiple images (e.g. frames of the animation), concatenate them into one array `data`.
- When working with less than four components, set the remaining components to a constant value (e.g. to zero)
- When working with transparency, premultiply color components by transparency (otherwise, rgba(1,1,1,0) would be closer to rgba(1,1,1,1) than to rgba(0,0,0,0) - transparent mapped to white instead of transparent)

# accepts

Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
In addition to negotiator, it allows:
- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
as well as `('text/html', 'application/json')`.
- Allows type shorthands such as `json`.
- Returns `false` when no types match
- Treats non-existent headers as `*`
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```sh
$ npm install accepts
```
## API
```js
var accepts = require('accepts')
```
### accepts(req)
Create a new `Accepts` object for the given `req`.
#### .charset(charsets)
Return the first accepted charset. If nothing in `charsets` is accepted,
then `false` is returned.
#### .charsets()
Return the charsets that the request accepts, in the order of the client's
preference (most preferred first).
#### .encoding(encodings)
Return the first accepted encoding. If nothing in `encodings` is accepted,
then `false` is returned.
#### .encodings()
Return the encodings that the request accepts, in the order of the client's
preference (most preferred first).
#### .language(languages)
Return the first accepted language. If nothing in `languages` is accepted,
then `false` is returned.
#### .languages()
Return the languages that the request accepts, in the order of the client's
preference (most preferred first).
#### .type(types)
Return the first accepted type (and it is returned as the same text as what
appears in the `types` array). If nothing in `types` is accepted, then `false`
is returned.
The `types` array can contain full MIME types or file extensions. Any value
that is not a full MIME type is passed to `require('mime-types').lookup`.
#### .types()
Return the types that the request accepts, in the order of the client's
preference (most preferred first).
## Examples
### Simple type negotiation
This simple example shows how to use `accepts` to return a different typed
respond body based on what the client wants to accept. The server lists it's
preferences in order and will get back the best match between the client and
server.
```js
var accepts = require('accepts')
var http = require('http')
function app (req, res) {
var accept = accepts(req)
// the order of this list is significant; should be server preferred order
switch (accept.type(['json', 'html'])) {
case 'json':
res.setHeader('Content-Type', 'application/json')
res.write('{"hello":"world!"}')
break
case 'html':
res.setHeader('Content-Type', 'text/html')
res.write('<b>hello, world!</b>')
break
default:
// the fallback is text/plain, so no need to specify it above
res.setHeader('Content-Type', 'text/plain')
res.write('hello, world!')
break
}
res.end()
}
http.createServer(app).listen(3000)
```
You can test this out with the cURL program:
```sh
curl -I -H'Accept: text/html' http://localhost:3000/
```

# `append-field`
A [W3C HTML JSON forms spec](http://www.w3.org/TR/html-json-forms/) compliant
field appender (for lack of a better name). Useful for people implementing
`application/x-www-form-urlencoded` and `multipart/form-data` parsers.
It works best on objects created with `Object.create(null)`. Otherwise it might
conflict with variables from the prototype (e.g. `hasOwnProperty`).
## Installation
```sh
npm install --save append-field
```
## Usage
```javascript
var appendField = require('append-field')
var obj = Object.create(null)
appendField(obj, 'pets[0][species]', 'Dahut')
appendField(obj, 'pets[0][name]', 'Hypatia')
appendField(obj, 'pets[1][species]', 'Felis Stultus')
appendField(obj, 'pets[1][name]', 'Billie')
console.log(obj)
```
```text
{ pets:
[ { species: 'Dahut', name: 'Hypatia' },
{ species: 'Felis Stultus', name: 'Billie' } ] }
```
## API
### `appendField(store, key, value)`
Adds the field named `key` with the value `value` to the object `store`.

base64-js
=========
`base64-js` does basic base64 encoding/decoding in pure JS.
[![build status](https://secure.travis-ci.org/beatgammit/base64-js.png)](http://travis-ci.org/beatgammit/base64-js)
Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.
Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.
## install
With [npm](https://npmjs.org) do:
`npm install base64-js` and `var base64js = require('base64-js')`
For use in web browsers do:
`<script src="base64js.min.js"></script>`
[Get supported base64-js with the Tidelift Subscription](https://tidelift.com/subscription/pkg/npm-base64-js?utm_source=npm-base64-js&utm_medium=referral&utm_campaign=readme)
## methods
`base64js` has three exposed functions, `byteLength`, `toByteArray` and `fromByteArray`, which both take a single argument.
* `byteLength` - Takes a base64 string and returns length of byte array
* `toByteArray` - Takes a base64 string and returns a byte array
* `fromByteArray` - Takes a byte array and returns a base64 string

# bcrypt.js
Optimized bcrypt in JavaScript with zero dependencies, with TypeScript support. Compatible to the C++
[bcrypt](https://npmjs.org/package/bcrypt) binding on Node.js and also working in the browser.
[![Build Status](https://img.shields.io/github/actions/workflow/status/dcodeIO/bcrypt.js/test.yml?branch=main&label=test&logo=github)](https://github.com/dcodeIO/bcrypt.js/actions/workflows/test.yml) [![Publish Status](https://img.shields.io/github/actions/workflow/status/dcodeIO/bcrypt.js/publish.yml?branch=main&label=publish&logo=github)](https://github.com/dcodeIO/bcrypt.js/actions/workflows/publish.yml) [![npm](https://img.shields.io/npm/v/bcryptjs.svg?label=npm&color=007acc&logo=npm)](https://www.npmjs.com/package/bcryptjs)
## Security considerations
Besides incorporating a salt to protect against rainbow table attacks, bcrypt is an adaptive function: over time, the
iteration count can be increased to make it slower, so it remains resistant to brute-force search attacks even with
increasing computation power. ([see](http://en.wikipedia.org/wiki/Bcrypt))
While bcrypt.js is compatible to the C++ bcrypt binding, it is written in pure JavaScript and thus slower ([about 30%](https://github.com/dcodeIO/bcrypt.js/wiki/Benchmark)), effectively reducing the number of iterations that can be
processed in an equal time span.
The maximum input length is 72 bytes (note that UTF-8 encoded characters use up to 4 bytes) and the length of generated
hashes is 60 characters. Note that maximum input length is not implicitly checked by the library for compatibility with
the C++ binding on Node.js, but should be checked with `bcrypt.truncates(password)` where necessary.
## Usage
The package exports an ECMAScript module with an UMD fallback.
```
$> npm install bcryptjs
```
```ts
import bcrypt from "bcryptjs";
```
### Usage with a CDN
- From GitHub via [jsDelivr](https://www.jsdelivr.com):<br />
`https://cdn.jsdelivr.net/gh/dcodeIO/bcrypt.js@TAG/index.js` (ESM)
- From npm via [jsDelivr](https://www.jsdelivr.com):<br />
`https://cdn.jsdelivr.net/npm/bcryptjs@VERSION/index.js` (ESM)<br />
`https://cdn.jsdelivr.net/npm/bcryptjs@VERSION/umd/index.js` (UMD)
- From npm via [unpkg](https://unpkg.com):<br />
`https://unpkg.com/bcryptjs@VERSION/index.js` (ESM)<br />
`https://unpkg.com/bcryptjs@VERSION/umd/index.js` (UMD)
Replace `TAG` respectively `VERSION` with a [specific version](https://github.com/dcodeIO/bcrypt.js/releases) or omit it (not recommended in production) to use latest.
When using the ESM variant in a browser, the `crypto` import needs to be stubbed out, for example using an [import map](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script/type/importmap). Bundlers should omit it automatically.
### Usage - Sync
To hash a password:
```ts
const salt = bcrypt.genSaltSync(10);
const hash = bcrypt.hashSync("B4c0/\/", salt);
// Store hash in your password DB
```
To check a password:
```ts
// Load hash from your password DB
bcrypt.compareSync("B4c0/\/", hash); // true
bcrypt.compareSync("not_bacon", hash); // false
```
Auto-gen a salt and hash:
```ts
const hash = bcrypt.hashSync("bacon", 10);
```
### Usage - Async
To hash a password:
```ts
const salt = await bcrypt.genSalt(10);
const hash = await bcrypt.hash("B4c0/\/", salt);
// Store hash in your password DB
```
```ts
bcrypt.genSalt(10, (err, salt) => {
bcrypt.hash("B4c0/\/", salt, function (err, hash) {
// Store hash in your password DB
});
});
```
To check a password:
```ts
// Load hash from your password DB
await bcrypt.compare("B4c0/\/", hash); // true
await bcrypt.compare("not_bacon", hash); // false
```
```ts
// Load hash from your password DB
bcrypt.compare("B4c0/\/", hash, (err, res) => {
// res === true
});
bcrypt.compare("not_bacon", hash, (err, res) => {
// res === false
});
```
Auto-gen a salt and hash:
```ts
await bcrypt.hash("B4c0/\/", 10);
// Store hash in your password DB
```
```ts
bcrypt.hash("B4c0/\/", 10, (err, hash) => {
// Store hash in your password DB
});
```
**Note:** Under the hood, asynchronous APIs split an operation into small chunks. After the completion of a chunk, the execution of the next chunk is placed on the back of the [JS event queue](https://developer.mozilla.org/en/docs/Web/JavaScript/EventLoop), efficiently yielding for other computation to execute.
### Usage - Command Line
```
Usage: bcrypt <input> [rounds|salt]
```
## API
### Callback types
- **Callback<`T`>**: `(err: Error | null, result?: T) => void`<br />
Called with an error on failure or a value of type `T` upon success.
- **ProgressCallback**: `(percentage: number) => void`<br />
Called with the percentage of rounds completed (0.0 - 1.0), maximally once per `MAX_EXECUTION_TIME = 100` ms.
- **RandomFallback**: `(length: number) => number[]`<br />
Called to obtain random bytes when both [Web Crypto API](http://www.w3.org/TR/WebCryptoAPI/) and Node.js
[crypto](http://nodejs.org/api/crypto.html) are not available.
### Functions
- bcrypt.**genSaltSync**(rounds?: `number`): `string`<br />
Synchronously generates a salt. Number of rounds defaults to 10 when omitted.
- bcrypt.**genSalt**(rounds?: `number`): `Promise<string>`<br />
Asynchronously generates a salt. Number of rounds defaults to 10 when omitted.
- bcrypt.**genSalt**([rounds: `number`, ]callback: `Callback<string>`): `void`<br />
Asynchronously generates a salt. Number of rounds defaults to 10 when omitted.
- bcrypt.**truncates**(password: `string`): `boolean`<br />
Tests if a password will be truncated when hashed, that is its length is greater than 72 bytes when converted to UTF-8.
- bcrypt.**hashSync**(password: `string`, salt?: `number | string`): `string`
Synchronously generates a hash for the given password. Number of rounds defaults to 10 when omitted.
- bcrypt.**hash**(password: `string`, salt: `number | string`): `Promise<string>`<br />
Asynchronously generates a hash for the given password.
- bcrypt.**hash**(password: `string`, salt: `number | string`, callback: `Callback<string>`, progressCallback?: `ProgressCallback`): `void`<br />
Asynchronously generates a hash for the given password.
- bcrypt.**compareSync**(password: `string`, hash: `string`): `boolean`<br />
Synchronously tests a password against a hash.
- bcrypt.**compare**(password: `string`, hash: `string`): `Promise<boolean>`<br />
Asynchronously compares a password against a hash.
- bcrypt.**compare**(password: `string`, hash: `string`, callback: `Callback<boolean>`, progressCallback?: `ProgressCallback`)<br />
Asynchronously compares a password against a hash.
- bcrypt.**getRounds**(hash: `string`): `number`<br />
Gets the number of rounds used to encrypt the specified hash.
- bcrypt.**getSalt**(hash: `string`): `string`<br />
Gets the salt portion from a hash. Does not validate the hash.
- bcrypt.**setRandomFallback**(random: `RandomFallback`): `void`<br />
Sets the pseudo random number generator to use as a fallback if neither [Web Crypto API](http://www.w3.org/TR/WebCryptoAPI/) nor Node.js [crypto](http://nodejs.org/api/crypto.html) are available. Please note: It is highly important that the PRNG used is cryptographically secure and that it is seeded properly!
## Building
Building the UMD fallback:
```
$> npm run build
```
Running the [tests](./tests):
```
$> npm test
```
