PdfExportOptions.PdfACompatibility- PdfExportOptions.AdditionalMetadata
If the PdfExportOptions.PdfACompatibility property is set to PdfACompatibility.None (the default value), the resulting document will conform to the ISO 32000-1:2005 standard without any restrictions.
For a code sample, refer to the following example online: How to export a report to ZUGFeRD.
For the current versions of the library, consider the following restrictions associated with PDF/A compatibility:
- All PDF/A versions implicitly prohibit encryption.
- All fonts that are used in PDF/A documents should be embedded.
- The PDF/A-1 and PDF/A-2 standards do not support attachments.
- The PDF/A-1 standard does not support transparency, and the alpha channel in images is ignored.
To check the validity of PDF export options, use the PdfExportOptions.Validate method that returns a list of any detected inconsistencies.
