This package is a ServiceProvider for Snappy: [https://github.com/KnpLabs/snappy](https://github.com/KnpLabs/snappy).



### Wkhtmltopdf Installation



Choose one of the following options to install wkhtmltopdf/wkhtmltoimage.



1. Download wkhtmltopdf from [here](http://wkhtmltopdf.org/downloads.html); 

2. Or install as a composer dependency. See [wkhtmltopdf binary as composer dependencies](https://github.com/KnpLabs/snappy#wkhtmltopdf-binary-as-composer-dependencies) for more information.



#### Attention! Please note that some dependencies (libXrender for example) may not be present on your system and may require manual installation. 



### Testing the wkhtmltopdf installation



After installing you should be able to run wkhtmltopdf from the command line / shell.



If you went for the second option the binaries will be at `/vendor/h4cc/wkhtmltoimage-amd64/bin` and `/vendor/h4cc/wkhtmltopdf-amd64/bin`. 



#### Attention vagrant users!



Move the binaries to a path that is not in a synced folder, for example:



```bash

cp vendor/h4cc/wkhtmltoimage-amd64/bin/wkhtmltoimage-amd64 /usr/local/bin/

cp vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64 /usr/local/bin/

```



and make it executable:



```bash

chmod +x /usr/local/bin/wkhtmltoimage-amd64 

chmod +x /usr/local/bin/wkhtmltopdf-amd64

```



This will prevent the error 126.



### Package Installation



Require this package in your composer.json and update composer.



```bash

composer require barryvdh/laravel-snappy

```



### Laravel



**Laravel 5.5** uses Package Auto-Discovery, so doesn't require you to manually add the ServiceProvider/Facade. If you also use laravel-dompdf, watch out for conflicts. It could be better to manually register the Facade.



After updating composer, add the ServiceProvider to the providers array in config/app.php



```php

Barryvdh\Snappy\ServiceProvider::class,

```



Optionally you can use the Facade for shorter code. Add this to your facades:



```php

'PDF' => Barryvdh\Snappy\Facades\SnappyPdf::class,

'SnappyImage' => Barryvdh\Snappy\Facades\SnappyImage::class,

```



Finally you can publish the config file:



```bash

php artisan vendor:publish --provider="Barryvdh\Snappy\ServiceProvider"

```



### Snappy config file



The main change to this config file (config/snappy.php) will be the path to the binaries.



For example, when loaded with composer, the line should look like:



```php

'binary' => base_path('vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64'),

```



If you followed the vagrant steps, the line should look like:



```php

'binary'  => '/usr/local/bin/wkhtmltopdf-amd64',

```



For windows users you'll have to add double quotes to the bin path for wkhtmltopdf:



```php

'binary' => '"C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf"'

```



### Lumen

In `bootstrap/app.php` add:



```php

class_alias('Barryvdh\Snappy\Facades\SnappyPdf', 'PDF');

$app->register(Barryvdh\Snappy\LumenServiceProvider::class);

```



Optionally, add the facades like so:



```php

class_alias(Barryvdh\Snappy\Facades\SnappyPdf::class, 'PDF');

class_alias(Barryvdh\Snappy\Facades\SnappyImage::class, 'SnappyImage');

```



To customise the configuration file, copy the file `/vendor/barryvdh/laravel-snappy/config/snappy.php` to the `/config` folder.



### Usage



You can create a new Snappy PDF/Image instance and load a HTML string, file or view name. You can save it to a file, or inline (show in browser) or download.



Using the App container:



```php

$snappy = App::make('snappy.pdf');

//To file

$html = '
Bill
You owe me money, dude.
';

$snappy->generateFromHtml($html, '/tmp/bill-123.pdf');

$snappy->generate('http://www.github.com', '/tmp/github.pdf');

//Or output:

return new Response(

    $snappy->getOutputFromHtml($html),

    200,

    array(

        'Content-Type'          => 'application/pdf',

        'Content-Disposition'   => 'attachment; filename="file.pdf"'

    )

);

```



Using the wrapper:



```php

$pdf = App::make('snappy.pdf.wrapper');

$pdf->loadHTML('
Test
');

return $pdf->inline();

```



Or use the facade:



```php

$pdf = PDF::loadView('pdf.invoice', $data);

return $pdf->download('invoice.pdf');

```



You can chain the methods:



```php

return PDF::loadFile('http://www.github.com')->inline('github.pdf');

```



You can change the orientation and paper size



```php

PDF::loadHTML($html)->setPaper('a4')->setOrientation('landscape')->setOption('margin-bottom', 0)->save('myfile.pdf')

```



If you need the output as a string, you can get the rendered PDF with the output() function, so you can save/output it yourself.



See the [wkhtmltopdf manual](http://wkhtmltopdf.org/usage/wkhtmltopdf.txt) for more information/settings.



### Testing - PDF fake



As an alternative to mocking, you may use the `PDF` facade's `fake` method. When using fakes, assertions are made after the code under test is executed:



```php
