Aspose.Slides PPTX to PDF with embedded charts

Aspose.Slides Product Family

I’m trying to convert a PPTX to PDF with embedded charts but I am getting a NullReference exception. My code is as follows:

WriteLogMessage($"{convDoc.FileExtension} Conversion.", log, Enumerations.LogLevel.Information);

                                        Aspose.Slides.License slidesLic = new Aspose.Slides.License();
                                        slidesLic.SetLicense("Aspose.Total.lic");

                                        WriteLogMessage("Creating in memory Aspose document from the memory stream.", log, Enumerations.LogLevel.Information);
                                        Presentation presentation = new Presentation(inMemStrm);

                                        WriteLogMessage("Saving Aspose document as PDF to output memory stream.", log, Enumerations.LogLevel.Information);

                                        Aspose.Slides.Export.PdfOptions slideSaveOptions = new Aspose.Slides.Export.PdfOptions();

                                        slideSaveOptions.SaveMetafilesAsPng = true;
                                        slideSaveOptions.JpegQuality = (byte)100;
                                        slideSaveOptions.TextCompression = Aspose.Slides.Export.PdfTextCompression.Flate;
                                        slideSaveOptions.SufficientResolution = 300;

                                        slideSaveOptions.Compliance = Aspose.Slides.Export.PdfCompliance.PdfA1b;

                                        presentation.Save(outMemStrm, Aspose.Slides.Export.SaveFormat.Pdf, slideSaveOptions);

If I remove the charts from the source file they convert without issue.

Hi



I can’t share the exact file we have had issues with for commercial reasons, but I created a new presentation with a chart in it and I have the same issues. I have attached this one.



Thanks



James
