Problem with fonts converting existing PDF into PDF/A3

Aspose.PDF Product Family

Hello
I’m trying to convert and existing PDF into PDF/A3u. The first try I made was following this code:

[https://blog.aspose.com/2015/08/24/pdf-to-pdfa-3a-conversion-create-pdfa3-and-attach-xml-remove-or-manipulate-tables-in-existing-pdf-file-with-aspose.pdf-for-java-10.6.0/]

But when I open the PDF result, acrobat reader tells me that there is a problem. The alert message is “It can`t extract the embebed font Arial …”. In the log, I can see a few messages with error severity:

  • The LZWDecode filter is prohibited
  • Font ‘SansSerif’ is not embedded
  • The trailer dictionary does not contain ‘ID’
  • Metadata key does not exists

So, I tried to embed the fonts correctly into the document first, following this code:

Embedding Fonts in an existing PDF file

The process finished with no errors, but I cannot open the result document.

What am I doing wrong?

Thanks in advance.

I`m using Aspose.PDF for .NET v19.6

Hi Farhan

The zip bellow contains the input, output (out) and the log conversion.
14048710_filesv2.zip (1.1 MB)

This is the code I’m executing, in order to convert the input pdf into PDF/A3u

using (FileStream file = new FileStream(logConversion, FileMode.Create, System.IO.FileAccess.Write))
{
Aspose.Pdf.Document doc = new Aspose.Pdf.Document(input);
doc.Convert(file, PdfFormat.PDF_A_3U, ConvertErrorAction.Delete);
doc.Save(output);
}

Many thanks.
