Snappy
Snappy is a PHP library allowing thumbnail, snapshot or PDF generation from a url or a html page. It uses the excellent webkit-based wkhtmltopdf and wkhtmltoimage available on OSX, linux, windows.
You will have to download wkhtmltopdf 0.12.x in order to use Snappy.
Please, check FAQ before opening a new issue. Snappy is a tiny wrapper around wkhtmltox, so lots of issues are already answered, resolved or wkhtmltox ones.

wkhtmltopdf binary as composer dependencies
If you want to download wkhtmltopdf and wkhtmltoimage with composer you add to composer.json:
$ composer require h4cc/wkhtmltopdf-i386 0.12.x
$ composer require h4cc/wkhtmltoimage-i386 0.12.x
or this if you are in 64 bit based system:
$ composer require h4cc/wkhtmltopdf-amd64 0.12.x
$ composer require h4cc/wkhtmltoimage-amd64 0.12.x
And then you can use it
use Knp\Snappy\Pdf;
$myProjectDirectory = '/path/to/my/project';
$snappy = new Pdf($myProjectDirectory . '/vendor/h4cc/wkhtmltopdf-i386/bin/wkhtmltopdf-i386');
// or
$snappy = new Pdf($myProjectDirectory . '/vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64');
N.B. These static binaries are extracted from Debian7 packages, so it might not be compatible with non-debian based linux distros
Some use cases
If you want to generate table of contents and you want to use custom XSL stylesheet, do the following:
$snappy = new Pdf('/path/to/binary');
$snappy->setOption('toc', true);
$snappy->setOption('xsl-style-sheet', 'http://path/to/stylesheet.xsl') //or local file;
$snappy->generateFromHtml('Some content
', 'test.pdf');
Bugs & Support
If you found a bug please fill a detailed issue with all the following points. If you need some help, please at least provide a complete reproducer so we could help you based on facts rather than assumptions.
- OS and its version
- Wkhtmltopdf, its version and how you installed it
