Thank you for reporting the issue.
Please check your results using the latest version of Aspose.Slides for C++ if it is possible. If the issue persists, please share and specify the following:

I upgraded the Aspose version to latest 22.1 . Result was the same . Incidentally the exporting of PPTX to other formats ( Save) is working fine.

Hi:
Thank you .
I tried using this to add a PDF to a PPT.
Case 1: If I use a PDF that is saved from a PPTX mostly it works ok.
Case 2: For standard PDFs generated via Adobe it either gives this error
Error System::NotImplementedException: void System::Drawing::Pen::set_DashCap(Drawing2D::DashCap)
Case 3: OR the generated PPTX dont open directly on MS PPTX , giving this errorScreenshot 2022-04-22 at 12.20.24 AM.jpg (50.2 KB)
