Hi,
I use this snippet to open and resave the ppt file on Linux.
using (var presentation = new Presentation(inFile))
{
SaveFormat format = SaveFormat.Ppt;
presentation.Save(tempFile, format);
}

There is a chart shadow appearing on slide 25 of the output file. Also, the font is changed.

@dunghnguyen,
Thank you for the issue description.

I reproduced the problem with chart shadows and logged the issue with ID SLIDESNET-42887 in our tracking system. Our development team will investigate this case. You will be notified when the issue is resolved.

As for the font, you can make sure it is not applied on your left screenshot (input presentation). Instead, PowerPoint displays Calibri font. Please check the following possible reasons:

  • “Akzidenz Grotesk” font was not installed (where PowerPoint was opened)
  • in the presentation, the name “AkzidenzGrotesk” (without whitespace) must be specified instead of “Akzidenz Grotesk” font_list.png (211.6 KB)
