FPDF/FPDI Error: Fatal error: Class 'setasign\Fpdi\FpdfTpl' not found in

I am attempting to watermark an existing PDF document, and this error has been tripping me up for the past two days...

I have the FPDI library in fpdi/src/, and the fpdf library in /fpdf/

The file throwing the error is Fpdi.php (line 27). Here are the first 30 lines:

<?php
/**
 * This file is part of FPDI
 *
 * @package   setasign\Fpdi
 * @copyright Copyright (c) 2017 Setasign - Jan Slabon (https://www.setasign.com)
 * @license   http://opensource.org/licenses/mit-license The MIT License
 * @version   2.0.0
 */
 

namespace setasign\Fpdi;

use setasign\Fpdi\PdfParser\CrossReference\CrossReferenceException;
use setasign\Fpdi\PdfParser\Type\PdfIndirectObject;
use setasign\Fpdi\PdfParser\Type\PdfNull;
//use setasign\Fpdi\FpdfTpl;

/**
 * Class Fpdi
 *
 * This class let you import pages of existing PDF documents into a reusable structure for FPDF.
 *
 * @package setasign\Fpdi
 */
class Fpdi extends FpdfTpl
{
    use FpdiTrait;

Here is my file that I am using to watermark the .pdf document on the fly:

<?php
	$fullPathToFile = $_GET['fileToWaterMark'];
	
	require('rotation.php');

    require_once('fpdf/fpdf.php');
	require_once 'fpdi/src/fpdi.php';
	require_once('fpdi/src/FpdfTpl.php');


	class PDF_Rotate extends FPDI {

	var $angle = 0;

	function Rotate($angle, $x = -1, $y = -1) {
		if ($x == -1)
			$x = $this->x;
		if ($y == -1)
			$y = $this->y;
		if ($this->angle != 0)
			$this->_out('Q');
		$this->angle = $angle;
		if ($angle != 0) {
			$angle*=M_PI / 180;
			$c = cos($angle);
			$s = sin($angle);
			$cx = $x * $this->k;
			$cy = ($this->h - $y) * $this->k;
			$this->_out(sprintf('q %.5F %.5F %.5F %.5F %.2F %.2F cm 1 0 0 1 %.2F %.2F cm', $c, $s, -$s, $c, $cx, $cy, -$cx, -$cy));
		}
	}

	function _endpage() {
		if ($this->angle != 0) {
			$this->angle = 0;
			$this->_out('Q');
		}
		parent::_endpage();
	}

	}



	//$fullPathToFile = "chinmay235.pdf";

	class PDF extends PDF_Rotate {

	var $_tplIdx;

	function Header() {
		global $fullPathToFile;

		//Put the watermark
		$this->Image('http://chart.googleapis.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World', 40, 100, 100, 0, 'PNG');
		$this->SetFont('Arial', 'B', 50);
		$this->SetTextColor(255, 192, 203);
		$this->RotatedText(20, 230, 'Raddyx Technologies Pvt. Ltd.', 45);

		if (is_null($this->_tplIdx)) {

			// THIS IS WHERE YOU GET THE NUMBER OF PAGES
			$this->numPages = $this->setSourceFile($fullPathToFile);
			$this->_tplIdx = $this->importPage(1);
		}
		$this->useTemplate($this->_tplIdx, 0, 0, 200);


	}

	function RotatedText($x, $y, $txt, $angle) {
		//Text rotated around its origin
		$this->Rotate($angle, $x, $y);
		$this->Text($x, $y, $txt);
		$this->Rotate(0);
	}

	}


	$pdf = new PDF();
	$pdf->AddPage();
	$pdf->SetFont('Arial', '', 12);
	$pdf->Output();
	?>

I am fairly competent with PHP, but this error has really thrown me for a loop. If any more information is needed, let me know and I will provide it.

For what it's worth, I just changed all the functions to from "protected" to "public" that were causing issues. Worked for me!

Require the classes this way:

require_once('fpdf/fpdf.php');
require_once('fpdi/src/autoload.php');

Then add use \setasign\Fpdi\Fpdi; to your watermark and not only use \setasign\Fpdi; or use the correct class name (including the full namespace) in your class declaration.

What happens if you change this:

require_once('fpdf/fpdf.php');
require_once 'fpdi/src/fpdi.php';
require_once('fpdi/src/FpdfTpl.php');

To this?

require_once('fpdf/fpdf.php');
require_once('fpdi/src/autoload.php');

Or if you don't have autoload then you maybe need to add:

require_once('fpdi/src/FpdiTrait.php');
