The PDFCompatibilityLevel enumeration is used by the PDFFile.CompatibilityLevel property and is used to determine which compatibility (or version) level to use when creating or updating PDF files.
The following methods of the PDFFile class will use PDFFile.CompatibilityLevel when creating new or updating existing PDF files:
This example will check the version of a PDF file and convert it to PDF 1.4 if required.
