# PdfExport

A [reveal.js](https://github.com/hakimel/reveal.js/) 3.x / 4.x plugin to easly switch to the built-in PDF export mode and back by pressing a shortcut key.

## Installation

Copy this repository into the plugin folder of your reveal.js presentation, ie ```plugin/pdfexport```.

Add the plugin to the initialization of your presentation, as below.

### reveal 4.x

```javascript
<script src="plugin/pdfexport/pdfexport.js"></script>
// .. 
Reveal.initialize({
	// ...
	plugins: [
		// ..
		PdfExport,
	]
});
```

### reveal 3.x

```javascript
Reveal.initialize({
	// ...
	dependencies: [
		// ...
		{ src: 'plugin/pdfexport/pdfexport.js', async: true },
	]
});
```

For **reveal 3.x only** you need to remove all of the following or similar lines from your presentation. Paper- or PDF-stylesheets will be set by the plugin.

```html
<!-- Printing and PDF exports -->
<script>
	var link = document.createElement( 'link' );
	link.rel = 'stylesheet';
	link.type = 'text/css';
	link.href = window.location.search.match( /print-pdf/gi ) ? 'css/print/pdf.css' : 'css/print/paper.css';
	document.getElementsByTagName( 'head' )[0].appendChild( link );
</script>
```

## Usage

To toggle between screen and PDF mode you can press the ```E``` shortcut on the keyboard.
