Could also be a string representing a path to a PDF file. strict: Determines whether user should be warned of all problems and also causes some correctable problems to be fatal. Defaults to ``False``. password: Decrypt PDF file at initialization. If the password is None, the file will not be decrypted. Defaults to ``None``.
