Answer 1

you can use the Zend library Zend_Barcode, see below a cose snippet I have used in the past.

$barcodeConfig = [
                'drawText' => false,
                'barThickWidth'=>'1',
                'barHeight'=>'30',
                'orientation' => 0,
                'text' => $shipment->getTrackingNumber()
            ];
            $rendererConfig = [
                'leftOffset' => $left,
                'topOffset' => $top
            ];
            $renderer = \Zend_Barcode::factory('code128', 'pdf', $barcodeConfig, $rendererConfig)->setResource($this->_getPdf(), 0);
            $renderer->draw();
