PHP library for converting the version of PDF files (for compatibility purposes).
- PHP 5.3+
- Ghostscript (gs command on Linux)
Run php composer.phar require xthiago/pdf-version-converter dev-master or add the follow lines to composer and run composer install:
{
"require": {
"xthiago/pdf-version-converter": "dev-master"
}
}
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');Is really simple add new implementation of guesser or converter, just implement GuessInterface or ConverterInterface.
Run phpunit -c tests.
