Aspose.PDF Java: PDF to PDF/A Convertion does not produce valid pdf_A_1A, pdf_A_2A, pdf_A_3A

Hello,
Using the latest Aspose.PDF java version (19.10) I am trying to convert some very simple PDFs to different PDF/A formats.
Here the code used:

com.aspose.pdf.Document pdfDocument = null;
try (InputStream in = new FileInputStream(filePath)){
	pdfDocument = new com.aspose.pdf.Document(in);
	pdfDocument.convert(getAsposePdfFactoryLogFile().getAbsolutePath(), getAsposePDFAType(pdfAType), ConvertErrorAction.Delete);
	pdfDocument.setLinearized(true);
	pdfDocument.save(filePath);
} catch(Exception ex) {
	throw new DocFactoryException(ex);
} finally {
	if(pdfDocument != null) {
		pdfDocument.close();
	}
}

The produced pdf_A_1A, pdf_A_2A, pdf_A_3A cannot be validated by diverses online tools, example https://www.pdf-online.com/osa/validate.aspx
The pdf_A_1B, pdf_A_2B and pdf_A_3B are recognized as valid PDF/A PDFs.

I have attached 6 PDFs produced by unit tests (we don’t load the license in unit tests that is why there is the license warning)
pdf_A_1A.pdf (46.1 KB)
pdf_A_1B.pdf (46.0 KB)
pdf_A_2A.pdf (46.1 KB)
pdf_A_2B.pdf (46.1 KB)
pdf_A_3A.pdf (46.1 KB)
pdf_A_3B.pdf (46.1 KB)

The https://www.pdf-online.com/osa/validate.aspx gives the following result:
Validating file “pdf_A_1A.pdf” for conformance level pdfa-1a
The key Type is required but missing.
The document does not conform to the requested standard.
The document doesn’t provide appropriate logical structure information.
The document does not conform to the PDF/A-1a standard.

Can you please check this at your side and fix this?

Emmanuel

@ecomba,

Can you please share complete environment details with us to further investigate this issue. Before sharing requested information can you please try to use Aspose.PDF latest version 20.4 on your end and if there is still an issue than please share feedback with us.

Hello,
I have tested again with the latests Aspose Version (20.4) and the problem is exactly the same. Only the PDF/A_xB can be validated.

Here are my settings

Java version: 11.0.6, vendor: AdoptOpenJDK, runtime: C:\Program Files\AdoptOpenJDK\jdk-11.0.6.10-hotspot
Default locale: fr_FR, platform encoding: Cp1252
OS name: “windows 10”, version: “10.0”, arch: “amd64”, family: “windows”

I have done the following tests using the license:

  • I generate a pdf with aspose.words (20.4) from a very simple template.docx (attached in the message below in a zip because docx are not allowed here).
  • then I convert the pdf with the code from my previous message
    All the PDFs claims to be PDF/A if I open them in Acrobat Reader

The produced pdf_A_1A, pdf_A_2A, pdf_A_3A cannot be validated by diverses online tools, example https://www.pdf-online.com/osa/validate.aspx
The pdf_A_1B, pdf_A_2B and pdf_A_3B are recognized as valid PDF/A PDFs.

The https://www.pdf-online.com/osa/validate.aspx gives the following result:
Validating file “pdf_A_1A.pdf” for conformance level pdfa-1a
The key Type is required but missing.
The document does not conform to the requested standard.
The document doesn’t provide appropriate logical structure information.
The document does not conform to the PDF/A-1a standard.

We investigated the earlier logged ticket and found that it was not Aspose.PDF bug, but incorrect validation of this service: www.pdf-online.com. Documents are valid according to standard. Adobe Acrobat DC Preflight cannot find any error (screenshots are attached).

Also, other online validations work well without any error:

Hi Asad,

Thanks a lot for your answer and for the online verification tool. this will help a lot.
But honestly, have you or your colleagues fixed something ? :sweat_smile:
For demonstrating all the problem I had, I have also used your online pdf conversion tool in the past:

Until last week it was slow and the result was only good with the PDF/A 1B. The PDF/A 3A was not recognized as PDF/A by Adobe Acrobat also.
I have done the test today: it is fast and the PDF/A 3A suddenly works.
Believe me I am really sure that the results were as described here (I was not the only one who has tested also) :smile:

Anyway thanks a lot. You can consider this thread as closed. I will comeback to you if I have any other issues.
Best regards
Emmanuel
