Convert PDF to PPTX using Aspose.PDF under linux docker - No graphics or lines in output

Hi, guys,
i have a problem when using Aspose.Pdf 20.2.0 (.NET) under Linux (Ubuntu).
When I try to convert a PDF with graphics to Powerpiont, no lines and graphics come along.
Only the text is taken. Can you see what the reason is.
This topic was more and more important for Docker.
I have attached the example source code and the example files.
I use the current version.
Files.zip (116.0 KB)
linux.png (19.9 KB)
AsposePDF2Powerpoint.zip (290.7 KB)
Thanks for your support.

@akquinet,

I have worked with source file shared by you on windows 10 environment and unable to observe the issue. For further investigation can you please complete environment details with us.SaveDoc.zip (37.3 KB)

Hi,
under windows 10 all works fine. I have problems under linux (ubuntu).
You must run my example under ubuntu.
Then the graphics and lines are missing.
Thanks for your support.
