Styles are lost after a simple Load & Save action (Reading and Writing)

[jmagnone]

I am trying to use the library for the first time to edit some text placeholders in a presentation (pptx or odp).

After loading the presentation with:

$pptReader = IOFactory::createReader('ODPresentation');
$oPHPPresentation = $pptReader->load('file.odp');

and then writing it to the output file as follows (where $writer is any of the available writers):

$pptWriter = IOFactory::createWriter($oPHPPresentation, $writer);
$pptWriter->save(__DIR__ . "/{$filename}.{$extension}");

the final presentation's shapes lost many of its styles and properties. Also, images embedded in the slide are lost.

A few comments:

• I didn't make any change between loading and writing it. My goal is to replace a text placeholder and save it, but while trying to solve the issue, I just commented part of the code leaving only the Reader and Writer sentences.
• I created the presentation in PowerPoint for Mac. While I tried to make this work, I saved the input as an odp file and tried to load it instead of the pptx. Also tried to load and save to pptx, ppt or odp with the undesired results. See screenshots below.
• Some styles I noticed are lost include the top, left, right and bottom margins which were not preserved from the input file, neither the "Do not autofit".

Input example:

Any ideas how to troubleshoot this?

I have similar problem.

When doing this: $pptReader = IOFactory::createReader('PowerPoint2007'); $oPHPPresentation = $pptReader->load('my_file.pptx'); echo write($oPHPPresentation, basename(__FILE__, '.php'), $writers);

I'm getting almost the same file, just all styling and images are missing :(

Any workaround for that?

Thanks!

@jmagnone Hi, have you got a sample file ?
