如何在windows Os中生成幼虫的PPT？

Question

我正在从我的database.It生成Powerpoint在ubuntu上运行良好，但不显示在windows.Only空白ppt显示.In窗口空白ppt是generated.my代码是

//创建幻灯片

    $currentSlide = $objPHPPowerPoint->getActiveSlide();

//创建一个形状(绘图)

    $shape = $currentSlide->createDrawingShape();
    $shape->setName('PHPPresentation logo')
        ->setDescription('PHPPresentation logo')
        ->setPath(base_path().'/public/images/pp_bg.jpg')
        ->setHeight(36)
        ->setOffsetX(10)
        ->setOffsetY(10);
    $shape->getShadow()->setVisible(true)
        ->setDirection(45)
        ->setDistance(10);

//创建一个形状(文本)

    $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' ) );



    // generate PPT file.
    $oWriterPPTX = IOFactory::createWriter($objPHPPowerPoint, 'PowerPoint2007');
    $oWriterPPTX->save("Proposal $id.ppt");
    $file_url = "Proposal $id.ppt";
    header('Content-Description: File Transfer');
    header('Content-Type: application/vnd.openxmlformats-officedocument.presentationml.presentation');
    header('Content-Disposition: attachment; filename='.basename($file_url));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' .filesize($file_url));

    readfile($file_url);
