   ByRef DetailedXMLOutput As String, _
   ByRef VerifiedConformance As PdfValidationConformance _
) As Boolean

public bool IsValidPDFA( 
   ref string DetailedXMLOutput,
   ref PdfValidationConformance VerifiedConformance
)

public function IsValidPDFA( 
   var  DetailedXMLOutput: String;
   var  VerifiedConformance: PdfValidationConformance
): Boolean;

public function IsValidPDFA( 
   DetailedXMLOutput : String,
   VerifiedConformance : PdfValidationConformance
) : boolean;

public: bool IsValidPDFA( 
   ref string* DetailedXMLOutput,
   ref PdfValidationConformance VerifiedConformance
)

public:
bool IsValidPDFA( 
   String^% DetailedXMLOutput,
   PdfValidationConformance% VerifiedConformance
)

Parameters

DetailedXMLOutput: Output parameter. Provides detailed validation result in machine readable XML report. If the file does not conform to the requested standard the XML report will summarize all problems that have been found durring the validation process.
VerifiedConformance: Output parameter. A member of the PdfValidationConformance enumeration. Provides information about the claimed conformance that the document was validated against.

Return Value

true if currently loaded document is Valid PDF/A document, otherwise returns false. The GdPicturePDF.GetStat method can be subsequently used to determine if this method has been successful.
