Can you tell me if Quick PDF Library is thread-safe? Can it be used in a multi-threaded environment?

Usually when the phrase "thread safe" is used it means that the same instance of the library can be accessed by different threads at the same time.

This means that Quick PDF Library is not thread safe because a single instance of Quick PDF Library can only be accessed by the thread that created the instance.

However, Quick PDF Library can be used in a multithreaded environment so long as a separate instance of the library is created by each thread.

For users of the ActiveX edition of the library, please note that this version has been compiled with the threading mode set to "single threaded apartment".
