ExaminerResults Methods

The ExaminerResults type exposes the following members.

Methods
  NameDescription
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodStatic memberCode exampleFromStream
Attempts to build an ExaminerResults object from the stream provided. To the greatest extent possible, FromStream attempts to get some information from the file. If the file is a PDF and it is encrypted, FromStream will throw an IncorrectPasswordException.
Note that many of the properties in the file cascade. For example, if IsPdf returns false, no other property will be valid. If IsEncrypted is true, no other properties except IsPdf, IsPdfA, and [P:IsIncorrectVersionForXrefStream] will be valid.
The properties within ExaminerResults are meant to reflect a very lightweight examination of the file and are in no way are exhaustive. PDF is a very complicated file format and there are a number of exceptions in the specification that are counter to the goal of having a light-weight interface to the information within the file. For example, because a PDF file presents information that indicates that it meets the archival variant, PDF/A, this doesn't guarantee that the document meets all requirements. ExaminerResults reflects what is advertised by the file and not necessarily the entire depth of content.
The stream position can not be counted on to be at a consistent location upon return.
The supplied passwords may either or both be null indicating no password. If passwords are supplied and the document is not encrypted, the passwords will be ignored. If the document is encrypted and the password(s) are incorrect or null FromStream will throw an IncorrectPasswordException.
Examples
The following example converts the rectangular points of an annotation into document space.
ConverterExample
public ExaminerResults ExaminePdf(Stream stm)
{
    ExaminerResults res = null;
    try {
        res = ExaminerResults.FromStream(stm, null, null);
        return res;
    }
    catch (IncorrectPasswordException) {
        while (true) {
            string password = GetPasswordFromUser();
            if (password == null) return null; // canceled
            try {
                res = ExaminerResults.FromStream(stm, password, null);
                return res;
            }
            catch (IncorrectPasswordException) { }
        }
    }
}
