How to Create Watermarked PDFs:

1. Scan your original certificates as PDF files

2. Use the following PHP script to add watermarks:

// watermark-generator.php
<?php
require('fpdf/fpdf.php');

// Function to add watermark
function addWatermark($inputFile, $outputFile, $watermarkText) {
    // Load existing PDF
    $pdf = new FPDF();
    
    // Add watermark to each page
    $pdf->SetFont('Arial', 'B', 48);
    $pdf->SetTextColor(200, 200, 200);
    
    // Set watermark at 45 degree angle
    $pdf->RotatedText(100, 150, $watermarkText, 45);
    
    // Save watermarked PDF
    $pdf->Output($outputFile, 'F');
}
?>
