How can one efficiently add a full-sized image as a background in a PDF generated using fpdf in PHP?

To efficiently add a full-sized image as a background in a PDF generated using fpdf in PHP, you can use the SetXY() function to position the image at coordinates (0,0) and then use the GetPageSize() function to set the image size to match the page size of the PDF. 

// Create a new PDF document
$pdf = new FPDF();
$pdf->AddPage();

// Set the position of the image to (0,0)
$pdf->SetXY(0, 0);

// Get the size of the page
$pageSize = $pdf->GetPageSize();
$pageWidth = $pageSize['w'];
$pageHeight = $pageSize['h'];

// Add the image as a background
$pdf->Image('path/to/image.jpg', 0, 0, $pageWidth, $pageHeight);

// Output the PDF
$pdf->Output();
