I am using Aspose.Slides.dll version 20.8.0.0. Problematic documents are attached below.
Sample PPT (1).pdf (18.8 KB)

Help me in this regards.
Thanks

@Wahaj_Khan,
Thank you for the query. Unfortunately, Aspose.Slides doesn’t yet support PDF/A-2a conformance for PDF export.

Could you please clarify, how did you convert the document to PDF/A-2a format?

Hi @Andrey_Potapov
First converted PPTX to PDF (non-pdfa) and than PDF to PDFA. Following is the code that we used for this purpose.

Convert from PPT to PDF

 using (FileStream CompressedFileStream = new FileStream(tempfile, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None))
                    {
                        Presentation.Save(CompressedFileStream, Aspose.Slides.Export.SaveFormat.Pdf);

                        long position = CompressedFileStream.Position;
                        CompressedFileStream.Seek(0, System.IO.SeekOrigin.Begin);
                        OutputFileBytes = new byte[position];
                        CompressedFileStream.Read(OutputFileBytes, 0, (int)position);
                    }

Convert PDF to PDFA/2A

 using (FileStream CompressedFileStream = new FileStream(tempfile, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None))
                {
                    PdfDocument.Info.ModDate = DateTime.Now;
                    PdfDocument.Convert(new MemoryStream(), PdfFormat.PDF_A_2A, ConvertErrorAction.Delete);
                    PdfDocument.Save(CompressedFileStream);
                    OutputFileBytes = new byte[CompressedFileStream.Length];
                    CompressedFileStream.Seek(0, System.IO.SeekOrigin.Begin);
                    CompressedFileStream.Read(OutputFileBytes, 0, (int)CompressedFileStream.Length);
                }

@Wahaj_Khan,
I added a ticket with ID SLIDESNET-42675 in our tracking system. Our development team will consider implementing this feature.

It looks like you use Aspose.Pdf for converting documents to PDF/A-2a format. I moved this thread to Aspose.Pdf Product Family forum. The support team will help you with failing validation of output files.

Could you please verify the attached output PDF/A file using Adobe Preflight? It was generated at our end using 21.6 version of the API.
