Adobe Reader opens a non pdf/a file as pdf/a after saving this file by Aspose.PDF

Aspose.PDF Product Family

Dear Aspose Support Team,

When I open the attached file PDF1.pdf in adobe reader, the message “This file claims compliance with the PDF/A standard and has been opened read-only to prevent modification.” appears not.

Then I open and save this file in C#, Aspose.PDF 23.5.0 with:

Aspose.Pdf.Facades.Form tmpPdfForm = new Aspose.Pdf.Facades.Form();
tmpPdfForm.BindPdf(PathOfPDF1)
tmpPdfForm.Save(OutputStream);

Before and after saving tmpPdfForm.Document.IsPdfaCompliant returns false.

Inserting

tmpPdfForm.Document.RemovePdfaCompliance();

before Save doesn’t help.

When I open the saved file (attached file PDF2.pdf) in adobe reader, the message “This file claims compliance with the PDF/A standard and has been opened read-only to prevent modification.” appears erroneously. We need this file as non PDF/A.

Thank you for your consideration. I look forward to hearing from you.

PDF1.pdf (1.8 MB)
PDF2.pdf (2.1 MB)

We could resolve the problem by adding this line of code:

_ = tmpPdfForm.Document.TaggedContent;
before
tmpPdfForm.Document.RemovePdfaCompliance();

This works also, PdfUa instead of Pdfa:

_ = tmpPdfForm.Document.TaggedContent;
tmpPdfForm.Document.RemovePdfUaCompliance();
