Hi,
we're using Aspose.PDF [.NET] to convert different kind of files to PDF/A.
Currently we're upgrading from Aspose.PDF v.9.8.0.0 to v.10.4.0.0. Thereby we've noticed a different behavior when converting annotated PDF files (StampAnnotation and HighlightAnnotation) to PDF/A-3B.
v.9.8.0.0
- The output log shows a violation of clause 6.5.3 for the HighlightAnnotations
- The output log don't contains any violation errors for the StampAnnotations
- However, HightlightAnnotations and StampAnnotations remain in the PDF/A file
v.10.4.0.0
- The output log shows a violation of clause 6.5.2 for HighlightAnnotations and StampAnnotations
- HighlightAnnotations and StampAnnotations are deleted in the PDF/A file
We're using your sample code from Convert PDF File To PDF/A with the option "ConvertErrorAction.Delete".
I can't find information in the PDF/A standard documentation that annotations are prohibited. Also Adobe Preflight and the 4Heights PDF/A validator don't show any violations for annotations.
Is there a reason why Aspose deletes annotations during the conversion to PDF/A?
Could you
provide us a solution for the problem? We need the annotations in the PDF/A document.
I've attached a sample PDF 1.7 document that I converted to PDF/A with v.9.8.0.0 and v.10.4.0.0. I've also attached the output logs of both conversions.
Best regards,
Julian
