# @jens-2020/pdfkit

A JavaScript PDF generation library for Node and the browser.

## Acknowledges

This project is a fork of [pdfkit](https://github.com/foliojs/pdfkit) by @devongovett and continued under the scope of this project since it has react-pdf specific features. Any recongnition should go to him and the original project mantainers.

## Description

PDFKit is a PDF document generation library for Node and the browser that makes creating complex, multi-page, printable documents easy.
It's written in CoffeeScript, but you can choose to use the API in plain 'ol JavaScript if you like. The API embraces
chainability, and includes both low level functions as well as abstractions for higher level functionality. The PDFKit API
is designed to be simple, so generating complex documents is often as simple as a few function calls.

Check out some of the [documentation and examples](http://pdfkit.org/docs/getting_started.html) to see for yourself!
You can also read the guide as a [self-generated PDF](http://pdfkit.org/docs/guide.pdf) with example output displayed inline.
If you'd like to see how it was generated, check out the README in the [docs](https://github.com/devongovett/pdfkit/tree/master/docs)
folder.

You can also try out an interactive in-browser demo of PDFKit [here](http://pdfkit.org/demo/browser.html).

# @jens-2020/png-js

A PNG decoder in JS for the canvas element or Node.js.

## Acknowledges

This project is a fork of [png.js](https://github.com/foliojs/png.js) by @devongovett and continued under the scope of this project since it has react-pdf specific features. Any recongnition should go to him and the original project mantainers.

## About this fork

> Updated to 977b857a11676c1e720e79ed8d9178a005a9abd6

- Build node and browser specific bundles
- Uses rollup for build
## Browser Usage

Simply include png.js and zlib.js on your HTML page, create a canvas element, and call PNG.load to load an image.

    <canvas></canvas>
    <script src="zlib.js"></script>
    <script src="png.js"></script>
    <script>
        var canvas = document.getElementsByTagName('canvas')[0];
        PNG.load('some.png', canvas);
    </script>

The source code for the browser version resides in `png.js` and also supports loading and displaying animated PNGs.

## Node.js Usage

Install the module using npm

    sudo npm install png-js

Require the module and decode a PNG

    var PNG = require('png-js');
    PNG.decode('some.png', function(pixels) {
        // pixels is a 1d array (in rgba order) of decoded pixel data
    });

You can also call `PNG.load` if you want to load the PNG (but not decode the pixels) synchronously.  If you already
have the PNG data in a buffer, simply use `new PNG(buffer)`.  In both of these cases, you need to call `png.decode`
yourself which passes your callback the decoded pixels as a buffer.  If you already have a buffer you want the pixels
copied to, call `copyToImageData` with your buffer and the decoded pixels as returned from `decodePixels`.
