Conversion of PDF to PDF/a paragraph justification lost

Hi Team,


I am having an issue when converting a PDF document to PDF/a 2A. I am using version 11.1.1.0 of pdf.Net for the conversion.

I am using the following code from the samples:

Document pdfDocument = new Document(inputFilename);
pdfDocument.Convert(outputFilename + “.log.xml”, PdfFormat.PDF_A_2A, ConvertErrorAction.Delete);
dfDocument.Optimize();
pdfDocument.Save(outputFilename);

I have tried this both with and without the Optimize function, but there was no visible difference in the justification of the PDF/a document, although the file size was greatly reduced.

Attached is the PDF File I used for the source as well as the converted target. You will notice that on the paragraphs that appear on pages of the PDF Document are justified but on the PDF/a the paragraphs are not.

Please help in resolving this issue
