Aspose.Pdf.Facades.Stamp to PDF/A Issues

Aspose.PDF Product Family
1

Hi

I am converting a word document to PDF using Aspose.Words.

I then use Aspose.Pdf.Facades.Stamp to apply a text or image stamp to the PDF.

I then use Aspose.Pdf.Document to convert the document to a PDF/A format.

The issue is that the resulting PDF does not contain the stamp and is not PDF/A compliant, if I don’t apply the stamp and convert the document the result is PDF/A compliant.

My question is, should I be able to convert a stamped document to a PDF/A format or is it not possible?

I can supply code and conversion logs files if required, I’d rather not post them in open forum.

Many thanks

Thanks for contacting support.

We have tested the scenario with Aspose.Pdf for .NET 17.11 and were able to convert one of our sample stamped PDFs into PDF/A-1a format.

You may please share your sample files and code snippet in a private message, so that we can test the scenario in our environment and address it accordingly.

Thanks for the prompt response. Would you be able to share your test code with me?

Thanks for writing back.

Please check following code snippet, which we have used to test the scenario in our environment:

// Open document.
Document pdfDocument = new Document("Original.pdf");

// Create stamp.
TextStamp textStamp = new TextStamp("Text Stamp")
{
 BottomMargin = 10,
 LeftMargin = 10,
 RightMargin = 10,
 VerticalAlignment = VerticalAlignment.Bottom,
 HorizontalAlignment = HorizontalAlignment.Left
};

// Process all pages.
foreach (Page page in pdfDocument.Pages)
{
 // Add stamp.
 page.AddStamp(textStamp);
}
pdfDocument.Convert(new MemoryStream(), PdfFormat.PDF_A_1A, ConvertErrorAction.Delete);
// Save the file.
pdfDocument.Save("Original_StampedOut.pdf");
