It started giving an error when opening PPTX generated after the update.

I was reviewing the issue, and it seems that the error occurs when updating phpoffice/common from version 1.0.4 to 1.0.5.

This happens even when running the examples provided by the library, even with a blank slide.

Error message from PowerPoint:

PowerPoint found a problem with the content in example.pptx.
PowerPoint can attempt to repair the presentation.
If you trust the source of this presentation, click Repair.

Example Code:

$ppt = new PhpPresentation();
$slide = $ppt->getActiveSlide();

    // Establecer color de fondo
    $backgroundColor = new Color();
    $backgroundColor->setColor(new StyleColor(StyleColor::COLOR_BLUE));
    $slide->setBackground($backgroundColor);

    // Guardar archivo en almacenamiento local
    $fileName = 'test1.pptx';
    $savePath = storage_path("app/{$fileName}");

    $writer = IOFactory::createWriter($ppt, 'PowerPoint2007');
    $writer->save($savePath);

    // Confirmar que se guardó correctamente
    if (Storage::exists($fileName)) {
        $this->info('Presentación guardada en: ' . $savePath);
    } else {
        $this->error('Error al guardar el archivo.');
    }

I think I found the cause, because we have this as well:

        $powerpoint = new PhpPresentation();

        $writer = IOFactory::createWriter($powerpoint, 'PowerPoint2007');

        header("Content-Type: application/vnd.openxmlformats-officedocument.presentationml.presentation");
        header("Content-Disposition: attachment; filename=presentation.pptx");

        $writer->save('php://output');

Can't get more basic than that. Anyway, the cause is that in the ppt/slideMasters/slideMaster1.xml file, this is written:

<a:lvl1pPr algn="ctr" indent="-324900.00000000006">

Instead of the required:

<a:lvl1pPr algn="ctr" indent="-324900">

I think the pixelsToEmu() function needs a rounding (phpoffice/common/src/Common/Drawing.php).
