Hi,
I am using Aspose.Net total, and I have the following issue: in Aspose.Pdf.dll version 7.1.0.0 I could convert a PDF document to PDF/A-1a format (albeit with some compliance errors), but that stopped working in version 7.2.0.0 and still doesn't work in version 7.3.0.0. The output document actually is a plain PDF version 1.4 document, not PDF/A at all. I use the .Net 1.1 version of the DLL.
If I try the same with PDF/A-1b, the output is as expected and the document does not have compliance errors.
When I roll back to the DLL version 7.1.0.0, PDF/A-1a works, but I would like to get rid of the PDF/A-1a compliance errors and I was hoping you fixed that in the newer builds.
I use this validator: http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx
PDF/A-1a validation errors with DLL version 7.1.0.0 are as follows:
| Validating file "test.doc (7.1, 1A).pdf" for conformance level pdfa-1a |
| The key MarkInfo is required but missing. |
| The document does not conform to the requested standard. |
| The document doesn't provide appropriate logical structure information. |
| Done. |
From my work with itextsharp I know that the "MarkInfo" and "logical structure" validation errors would be resolved by just marking the output PDF as Tagged, the validator does not even require tags to be actually present. As the source document in my test is MS Word and has a table of contents that is still clickable in the output PDF produced by Aspose, it should however be feasible to provide structure information.
Best regards,
