Convert HTML to PDF/A and PDF/X Documents

EVO PDF Client for .NET Documentation

EVO HTML to PDF Converter allows you to convert a HTML to full PDF, PDF/A subset or PDF/X subset. You can choose between these standards using the PdfDocumentOptionsPdfStandardSubset property. An object of PdfDocumentOptions type is exposed by the HtmlToPdfConverterPdfDocumentOptions property.

The PDF/A subset or PDF/X standards impose additional restrictions for the generated PDF document. For example, the PDF/A-1b standard, used for long-term archiving of PDF documents, requires that all the true type fonts used by the document to be embedded in the document, the HTTP links to be disabled, the document to not use transparent objects and the document information properties to be disabled.
