Einstiegspunkt

All documents start with Document::create():

use Yeeefang\TcpdfNext\Core\Document;

$pdf = Document::create()
    ->setTitle('My Document')
    ->addPage()
    ->setFont('Helvetica', '', 12)
    ->cell(0, 10, 'Hello World')
    ->save('output.pdf');

The Document class is final and implements PdfDocumentInterface. Its functionality comes from 12 composable traits — see Design Philosophy for details.
