Once you have the library installed, you can create a new controller method that generates the PDF file. Inside this method, you can use the library to generate the PDF file with the necessary content. You can then return the generated PDF as a response to the user.

        $pdf->loadHtml('<h1>Sample PDF</h1>');

        // Set options for watermark
        $options = new Options();
        $options->setIsPhpEnabled(true);

        // Load image for watermark
        $watermarkImage = public_path('watermark.png');

        // Add watermark to PDF
        $pdf->setWatermarkImage($watermarkImage);
        $pdf->render();

        return $pdf->stream();
    }
}

  2. Add a route to the generatePDFWithWatermark method in your routes/web.php file: 
1

Route::get('/generate-pdf', 'PDFController@generatePDFWithWatermark');


  1. Access the route in your browser (e.g., http://localhost:8000/generate-pdf) to generate the PDF file with the watermark.


By following these steps, you'll be able to watermark a PDF file generated in Laravel using the dompdf package. Feel free to customize the watermark image, position, and other settings according to your requirements.
