A value that indicates whether the engine has already run the operation.
public bool IsPostOperation { get; }
true if the engine has already run the operation; otherwise, false and the engine is about to run the operation.
The DocumentConverterJobs.JobOperation event occur twice for each operation, first with IsPostOperation set to false, meaning the engine is about to run this operation and then with IsPostOperation set to true, meaning the engine has run the operation.
DocumentConverterJobs.JobStarted and DocumentConverterJobs.JobCompleted events fire once each with IsPostOperation set to false always.
