For instance, we may implement WritePageAsync method in addition to the existing WritePage method. This is a similar scenario as in System.IO.StreamWriter class which has WriteLine and WriteLineAsync methods.

The PDF/A-1 standard uses the PDF Reference 1.4 and specifies two levels of compliance:

- PDF/A-1b - Its goal is to ensure reliable reproduction of the visual appearance of the document.

- PDF/A-1a - Its objective is to ensure that documents content can be searched and re-purposed. This compliance level has some additional requirements:

  • Document structure must be included.
  • Tagged PDF.
  • Unicode character maps
  • Language specification.

Since the PdfProcessing and its PdfFormatProvider is compliant with the PDF Reference 1.7. , the produced documents are created with this version as well:
