PDF not converted to PDF/A-1b and PDF/A-3b correctly

We have a text searchable PDF get from a scanner that need to be converted to PDF/A standard. We have used Aspose.PDF to convert it using the following code:

using (Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(pdfInputFilePath))
{
pdfDocument.Convert(logFilename, Aspose.Pdf.PdfFormat.PDF_A_1B, Aspose.Pdf.ConvertErrorAction.Delete);
pdfDocument.Save(pdfaOutputFilePath);
}

The final PDF got some squared characters in some places, other places the text are lost.
We have tried to convert that same original PDF using Adobe Acrobat XI Pro Preflight feature and see that it can convert successfully.
These are the results:
| Aspose.PDF | Adobe Acrobat XI Pro
----------------------------------------------------------------------
PDF_A_1A | Failed | Failed
----------------------------------------------------------------------
PDF_A_1B | Failed | Succesfully
----------------------------------------------------------------------
PDF_A_3B | Failed | Succesfully

Thanks.

I’ve attached the PDF here. Please take a look. Thanks.

Hi Aspose.PDF team,


Do you have any update on this issue?
It’s very urgent for us that you can fix this issue soon, because the process of converting PDF to PDF/A is a critical path for a PDF to be imported to our live production environment.

We are anxiously waiting for this fix. If it takes too long, we will consider switching to another library that support it better.

Thanks.
