Reading and writing PPTX leads to "destroyed" layout

[deeskayp]

Hey folks. I'm trying to open a .pptx template file, add my data and write it back as .pptx. However, if I just open the file and write it back, the layout is somehow destroyed.

Here's my code:

$reader = IOFactory::createReader('PowerPoint2007');
$presentation = $reader->load('template.pptx');
$writer = IOFactory::createWriter($presentation, 'PowerPoint2007');
$writer->save('result.pptx');

This is how the template looks like:

and this is the result:

I attached my template file:
template.pptx

I'm having exactly the same issue, overall, the saving process seems a bit broken. Displays vertical text instead of horizontal text, wrong font size, shapes aren't saved, image sizes aren't the same, audio/video isn't saved, etc. Unfortunantely this makes the library unusable if you are using slides from another pptx and you're not building the entire pptx from code.
