# Ghostscript PHP driver
[](http://travis-ci.org/alchemy-fr/Ghostscript-PHP)
# API usage
To instantiate Ghostscript driver, the easiest way is :
```php
$transcoder = Ghostscript\Transcoder::create();
```
You can customize your driver by passing a `Psr\Log\LoggerInterface` or
configuration options.
Available options are :
- `gs.binaries` : the path (or an array of potential paths) to the ghostscript binary.
- `timeout` : the timeout for the underlying process.
```php
$transcoder = Ghostscript\Transcoder::create(array(
'timeout' => 42,
'gs.binaries' => '/opt/local/gs/bin/gs',
), $logger);
```
To process a file to PDF format, use the `toPDF` method :
Third and fourth arguments are respectively the first page and the number of
page to transcode.
```php
$transcoder->toPDF('document.pdf', 'first-page.pdf', 1, 1);
```
To render a file to Image, use the `toImage` method :
```php
$transcoder->toImage('document.pdf', 'output.jpg');
```
## Silex service provider :
A [Silex](silex.sensiolabs.org) Service Provider is available, all parameters
are optionals :
```php
$app = new Silex\Application();
$app->register(new Ghostscript\GhostscriptServiceProvider(), array(
'ghostscript.configuration' => array(
'gs.binaries' => '/usr/bin/gs',
'timeout' => 42,
)
'ghostscript.logger' => $app->share(function () {
return $app['monolog']; // use Monolog service provider
}),
));
$app['ghostscript.pdf-transcoder']->toImage('document.pdf', 'image.jpg');
```
