Determines if the specified file is PDF/A.

Public Shared Function IsPdfA(
ByVal fileName As String
) As Boolean
public:
static bool IsPdfA(
String^ fileName

fileName
The name of the PDF file.
true if the specified file is PDF/A; otherwise, false.
This method checks whether the file claims to be PDF/A. The engine only checks if the file claims compliance with PDF/A standard and does not perform any validation.
This example will save a PDF file as a normal PDF first, then as PDF/A and verifies the claim.
