Usage

Guessing a version of PDF File:

<?php

// import the composer autoloader
require_once __DIR__.'/vendor/autoload.php'; 

// import the namespaces
use Xthiago\PDFVersionConverter\Guesser\RegexGuesser;
// [..]

$guesser = new RegexGuesser();
echo $guesser->guess('/path/to/my/file.pdf'); // will print something like '1.4'

Converting file to a new PDF version:

<?php

// import the composer autoloader
require_once __DIR__.'/vendor/autoload.php'; 

// import the namespaces
use Symfony\Component\Filesystem\Filesystem,
 Xthiago\PDFVersionConverter\Converter\GhostscriptConverterCommand,
 Xthiago\PDFVersionConverter\Converter\GhostscriptConverter;

// [..]

$command = new GhostscriptConverterCommand();
$filesystem = new Filesystem();

$converter = new GhostscriptConverter($command, $filesystem);
$converter->convert('/path/to/my/file.pdf', '1.4');
