Conversion to pdf/a: missing validation of Unicode font mapping

Aspose.PDF Product Family
1

Hello,
I have a pdf and convert it to pdf/a (Aspose.Pdf.PdfFormat.PDF_A_1A) after asking for validation.
The converted pdf/a doesn’t pass Adobe Pre-flight validation for Pdf/A1 because the file misses Unicode mapping for font.

Looking at the original file seems in effect that the original pdf was not complete and was missing the correct Unicode definition of the font used. But why the Validate step didn’t report the issue and the conversion is done anyway?

Thank you.
Best regards.

Thank you Tilal,

issue closed. After some smoke tests, managers decided a different approach. Just to give an hint, it seems that currently the Aspose validator does not handle any PDF-A requirement about color management.

Best regards,

Renato

Hi Rento,

Thanks for sharing your feedback and plan. However we will appreciate it if you can share your sample input/output document along with sample code. We will investigate and resolve the issue accordingly in our API, ultimately it will help us to improve the API.

Furthermore, following code is used to convert a PDF document to PDFA standard and validate it.

com.aspose.pdf.Document pdfDoc = new
com.aspose.pdf.Document(“input.pdf”);

PdfFormatConversionOptions opts = new
PdfFormatConversionOptions(“log.xml”, PdfFormat.PDF_A_1A, ConvertErrorAction.Delete);

opts.setOptimizeFileSize(true);

System.out.println(pdfDoc.convert(opts));

pdfDoc.save(“Test_PDF_A_1A.pdf”);

pdfDoc = new
com.aspose.pdf.Document(“Test_PDF_A_1A.pdf”);

pdfDoc.validate(“Validation_log.xml”, PdfFormat.PDF_A_1A);

pdfDoc.dispose();

We are sorry for the inconvenience.

Best Regards,
