Must be paired with an Initialize() method. Call this method when the application is disposed.
A call to an Initialize() method should be paired with a call to the Terminate method. The very first call to Initialize() will initialize the entire PDF library, while its paired call to Terminate method will de-initialize and release its memory. Multiple PDF initialization/termination pairs are supported in a multi-threaded PDF application, because it is required to initialize and terminate PDF in each child thread.
