Parameters

fileName

The name of the PDF or Postscript file.

pdfTypesOnly

true to recognize only PDF files (Postscript files will not be recognized), and PDFFileType.Unknown will be returned when fileName is a PS or EPS file. false to recognize both PDF and PS files.

Return Value

The Load method will internally call GetPDFFileType with pdfTypesOnly set to true before loading the file properties.

Generally, when loading PDF files call GetPDFFileType first to determine whether the file provided by the user is a valid PDF. After that, it is best to call IsEncrypted to determine whether the file is encrypted and ask the user for a password before loading the file.

For an example, refer to PDFCompatibilityLevel.
