Missed Text Box and Incorrect Font Size after PPTX to PPT Conversion in C#

Aspose.Slides Product Family

I have converted a *.pptx presentation to *.ppt format with Aspose.Slides and the result document have a few inconsistencies.

The most affected slides:

  • 1: no text box at the bottom of the slide.
  • 16: the font size is changed and text is shifting out of the slide margin.

There are screenshots of these issues in the attached archive, as well as, the presentation.

Code sample:

var pr = new Presentation(inPath);
pr.Save(outPath, SaveFormat.Ppt);

I use Aspose.Slides.dll 25.2.0.0 and Microsoft® PowerPoint® for Microsoft 365 MSO (Version 2501 Build 16.0.18429.20132) 64-bit.
