Remarks

The PDFFileType enumeration is used as the return value from PDFFile.GetPDFFileType method and as the type of the PDFDocument.FileType property. It determines the type and version of the PDF or PS file.

Note: The PDFDocument class can be associate with a PDF only and does not support Postscript files. As a result, the value of PDFDocument.FileType will only be one of the PDF version values.
