I use libtiff in a multi-threaded environment and I don't know of any major issues. The only thing I'm aware of that is not thread-safe is that libtiff uses a single pointer for the Error and Warning routines, so you need to always use the same routines (changing them in one thread changes them in all threads). It's easy to code around this using thread-specific flags. (In VC++, __declspec(thread) ).
