I am trying to install the magento2-pdf-generator2 extension, but I first need to install the mpdf library, I ran the composer require mpdf/mpdf command and then ran php bin/magento setup:upgrade and php bin/magento setup:static-content:deploy to clear the caches.

I tried the following example example and put it in a file called test1.php in the root directory:

require_once __DIR__ . '/vendor/autoload.php';

$mpdf = new \Mpdf\Mpdf();
$mpdf->WriteHTML('<h1>Hello world!</h1>');
$mpdf->Output();

But I am getting an error:

[31-May-2017 16:30:00 UTC] PHP Fatal error:  Uncaught Error: Class 'Mpdf\Mpdf' not found in /home/public_html/test1.php:4
Stack trace:
#0 {main}
  thrown in /home/public_html/test1.php on line 4

all that I have in my test file is:

<?php
require_once __DIR__ . '/vendor/autoload.php';

$mpdf = new \Mpdf\Mpdf();
$mpdf->WriteHTML('<h1>Hello world!</h1>');
$mpdf->Output();
?>

I do have the mbstring, gd, zlib and bcmath extensions enabled. I am unsure why it isn't loading
