Error Loading Files (ppt and pptx)

[sxaxmz]

Hi, I am trying to use this library to load and convert ppt and pptx files to pdf. Unfortunately, unlike PHPSpredsheet and PHPWord this library is not as rich in options when it comes to writers and options to do that.

I came up with a code to do that alternatively as a workaround but the library is not loading the files, the line that I use to load the file:

$presentation = PresentationIOFactory::load('path_to_file');

Errors that I get when I try to load each file:

PPTX File Load Error:

Stackoverflow link: Convert PPT and PPTX to PDF - PHP

Based on #710 I was able to overcome the issue of load pptx. Still facing issue with loading ppt as per the provided error.

@sxaxmz with the fix for #710, were you able to load/save pptx files containing notes (is there another part to the fix that I'm missing?)

@Offbeatmammal @sxaxmz Hi, Could you send me a sample file with error, please, for reproducing the bug ?
