as the title suggests, I'm looking to convert a powerpoint file (pptx) to PDF using python on linux. I have found and tested several solutions but most of them depend on Windows (pptxtoPDF, ComTypes, Pythoncom, PPT2PDF) or are paid like (Aspose.slides, Spire.Presentation, CloudMersive). I'd really like to find a package that can do this conversion without being paid for, without depending on Windows and without relying on Microsoft PowerPoint or other third-party applications and services.
Thanks in advance !
