It seems you are encountering a NullReferenceException when trying to convert a PDF to PPT using the PptxSaveOptions method in Aspose.PDF for .NET on your Red Hat Linux environment. This error typically indicates that there is an attempt to access an object that has not been initialized.

Here are a few steps you can take to troubleshoot and potentially resolve the issue:

  1. Check Object Initialization: Ensure that all objects, especially the PptxSaveOptions, are properly instantiated before use. For example, make sure you are creating an instance of PptxSaveOptions correctly.

    Aspose.Pdf.PptxSaveOptions pptx_save = new Aspose.Pdf.PptxSaveOptions();

  2. Verify PDF Document Loading: Ensure that the PDF document is being loaded correctly. If the document path is incorrect or the file is not accessible, it could lead to a null reference when trying to save.

    Aspose.Pdf.Document doc = new Aspose.Pdf.Document("path/to/your/input.pdf");

  3. Check for Licensing Issues: Since you mentioned that aspose.License is working fine, ensure that the license is applied correctly before performing any operations. Licensing issues can sometimes lead to unexpected behavior.

  4. Review Environment Compatibility: Since you are using Red Hat Linux, ensure that all dependencies and the environment are set up correctly for running Aspose.PDF. Sometimes, platform-specific issues can arise.

  5. Consult Documentation: For more detailed guidance on converting PDF to PPT, you can refer to the official documentation which provides step-by-step instructions and code examples. This can help ensure that you are following the correct procedure.

If the issue persists after checking these points, consider reaching out to Aspose support with detailed information about your environment and the code you are using. They may provide more specific insights based on your situation.
