@forasposeissues,
Thank you for contacting support.

Please share the following additional files and information:

  • sample presentation file
  • code example that reproduces the error
  • OS version on which the error occured
3

We have jdk 17.0_8l64 on our server.
Sample code which we are using -

String rightsWatchMark = (String) ppt.getDocumentProperties().get_Item("RightsWATCHMark");
String encodedRightsWatchMark = Base64.getEncoder().encodeToString(rightsWatchMark.getBytes());
com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document(outputPdfFilePath);
DocumentInfo documentProperty = pdfDocument.getInfo();
documentProperty.set_Item("RightsWATCHMark", encodedRightsWatchMark);
pdfDocument.save();

You can try with any PPT file. It is failing every time.

@forasposeissues,
Thank you for the additional information. You can see that the error occurs inside the Presentation.save method:

but your code example does not call the Presentation.save method.

Please check the issue carefully.

5

Yes, my bad. We are using

Presentation ppt = new Presentation(fileInputStream);
ppt.save(outputPdfFilePath,SaveFormat.Pdf,pdfOptions);
6

@forasposeissues,
Thank you for the code example. I am guessing that you are using the Aspose.Pdf.SaveFormat enum instead of Aspose.Slides.Export.SaveFormat when saving PowerPoint presentations. Please check this.

7

Checked code. We are using SaveFormat from Aspose slides.

@forasposeissues,
This is very simple code that usually works fine. We need more details to reproduce the issue you are experiencing.
