Problema con PhpOffice\PhpPresentation

[fermat]

ciao!

ho installato tramite composer PhpOffice\PhpPresentation.
poi ho creato uno script con il contenuto che ho trovato su github, racchiuso in try/catch:

require_once 'lib/vendor/autoload.php';

use PhpOffice\PhpPresentation\PhpPresentation;
use PhpOffice\PhpPresentation\IOFactory;
use PhpOffice\PhpPresentation\Style\Color;
use PhpOffice\PhpPresentation\Style\Alignment;

try {
    $objPHPPowerPoint = new PhpPresentation();

    $currentSlide = $objPHPPowerPoint->getActiveSlide();

// Create a shape (drawing)
    $shape = $currentSlide->createDrawingShape();
    $shape->setName('PHPPresentation logo')
        ->setDescription('PHPPresentation logo')
//    ->setPath('./resources/phppowerpoint_logo.gif')
        ->setHeight(36)
        ->setOffsetX(10)
        ->setOffsetY(10);
    $shape->getShadow()->setVisible(true)
        ->setDirection(45)
        ->setDistance(10);

// Create a shape (text)
    $shape = $currentSlide->createRichTextShape()
        ->setHeight(300)
        ->setWidth(600)
        ->setOffsetX(170)
        ->setOffsetY(180);
    $shape->getActiveParagraph()->getAlignment()->setHorizontal(Alignment::HORIZONTAL_CENTER);
    $textRun = $shape->createTextRun('Thank you for using PHPPresentation!');
    $textRun->getFont()->setBold(true)
        ->setSize(60)
        ->setColor(new Color('FFE06B20'));

    $oWriterPPTX = IOFactory::createWriter($objPHPPowerPoint, 'PowerPoint2007');
    $oWriterPPTX->save(__DIR__ . "/sample.pptx");
    $oWriterODP = IOFactory::createWriter($objPHPPowerPoint, 'ODPresentation');
    $oWriterODP->save(__DIR__ . "/sample.odp");
} catch (Exception $ex) {
    echo $ex->getMessage();
}

sulla pagina ottengo questo errore: The file "" doesn't exist

qualche idea??

ho attivato gli errori sul server e questo è quello che mi da:

Fatal error:  Uncaught  PhpOffice\PhpPresentation\Exception\FileNotFoundException: The file ""  doesn't exist in  /home/nvuasusi/public_html/api/lib/vendor/phpoffice/phppresentation/src/PhpPresentation/Shape/Drawing/File.php:85 Stack trace: #0  /home/nvuasusi/public_html/api/lib/vendor/phpoffice/phppresentation/src/PhpPresentation/Writer/PowerPoint2007/ContentTypes.php(133):  PhpOffice\PhpPresentation\Shape\Drawing\File->getMimeType() #1  /home/nvuasusi/public_html/api/lib/vendor/phpoffice/phppresentation/src/PhpPresentation/Writer/PowerPoint2007.php(124):   PhpOffice\PhpPresentation\Writer\PowerPoint2007\ContentTypes->render() #2 /home/nvuasusi/public_html/api/test.php(39):  PhpOffice\PhpPresentation\Writer\PowerPoint2007->save() #3 {main}   thrown in /home/nvuasusi/public_html/api/lib/vendor/phpoffice/phppresentation/src/PhpPresentation/Shape/Drawing/File.php on line 85

ok capito il problema, la riga commentata con il logo.
decommentandola, e dandogli il path corretto, funziona tutto.

<?php
