I need to convert a normal PDF document into a PDF A/1A
I have tried to do it in the following way but the resulting document gives me problems when incorporating a digital signature and then doing a “save as” from the acrobat reader (the signature indicates that the document was modified, that is, it is broken).
Dim doc As New Aspose.Pdf.Document(“c:\pdf\originalNotA.pdf”)
Dim options As New Aspose.Pdf.PdfFormatConversionOptions(Aspose.Pdf.PdfFormat.PDF_A_1A, Aspose.Pdf.ConvertErrorAction.Delete)
Is there a way to do the conversion from normal pdf to pdf A/1A without using the convert instruction?
Thank you very much for your help
