Combining multiple PPTX files into a single file using PresentationBuilder-issue

[alex.vinokikjParticipant]

Hi there,

I’m using OpenXMl Power Tools for combining multiple pptx files into a single files. But sometimes slides in the built presentation are not same as original ones. The elements on them are enlarged or reduced.

Example of reduced elements (see slide #2): https://1drv.ms/i/s!Ag1kK3U84USSjlAaC4xYxjoVxpj-

Here is how it looks like if the slides are merged in different order (elements on slide #2 are enlarged now): https://1drv.ms/i/s!Ag1kK3U84USSjk_3pp9Zu4QFXpWt

I’m using the following code in order to merge the slides into one file:

 var slides = new List<OpenXmlPowerTools.SlideSource>();

foreach (var slidePath in slidePaths)
     slides.Add(new OpenXmlPowerTools.SlideSource(new OpenXmlPowerTools.PmlDocument(slidePath), true));

OpenXmlPowerTools.PresentationBuilder.BuildPresentation(slides, presentationPath);

where, slidePaths is List of physical paths of the slides need to be combined, and presentationPath is the path where the new file should be saved.

Does anyone know why is this happening and how this can be fixed?

P.S. Following are the links for downloading the slides:
