Create PDF document from HTML contents

// Create a new pdf instance.
$pdf = Vianetz\Pdf\Model\PdfFactory::general()->create();

// Create the document. You can return any kind of HTML content here.
$document = new \Vianetz\Pdf\Model\Document();
$document->setHtmlContents('<strong>Hello</strong> World!');
// Add our document to the pdf. You can add as many documents as you like
// as they will all be merged into one PDF file.

// Save the resulting PDF to file test.pdf - That's it :-)

Merge a PDF file and a PDF string into one PDF file

// Load some random PDF contents
$pdfString = file_get_contents('test1.pdf');

// Setup things
$pdf = Vianetz\Pdf\Model\PdfFactory::general()->create();
$pdfMerge = Vianetz\Pdf\Model\PdfMerge::create();

// Do the merge.

// Save the result PDF to file result.pdf.
