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](http://wkhtmltopdf.org/)

available on OSX, linux, windows.



You will have to download wkhtmltopdf `0.12.x` in order to use Snappy.



Please, check [FAQ](doc/faq.md) before opening a new issue. Snappy is a tiny wrapper around wkhtmltox, so lots of issues are already answered, resolved or wkhtmltox ones.



Following integrations are available:

* [`knplabs/knp-snappy-bundle`](https://github.com/KnpLabs/KnpSnappyBundle), for Symfony

* [`barryvdh/laravel-snappy`](https://github.com/barryvdh/laravel-snappy), for Laravel

* [`mvlabs/mvlabs-snappy`](https://github.com/mvlabs/MvlabsSnappy), for Zend Framework

```bash

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:

```



## 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

* A complete reproducer with relevant php and html/css/js code



If your reproducer is big, please try to shrink it. It will help everyone to narrow the bug.
