```
    Closes any loaded document and releases threads pools created by the viewer. Usually, there is no need to call this method, as the the thread pool is automatically destroyed when the viewer is destroyed. However, to retain the viewer object in memory but release thread resources when a document is closed, call this method. If the viewer is made to load another document, it will create a fresh thread pool. That, however, is an expensive operation.
    
    Throws:
    
    IOException - if an I/O error occurs.
    
    PdfException - if an illegal argument is supplied.
