Creates a new PDF Handler. Each handler is automatically associated with it's own working thread, so that the calling code doesn't have to worry about threading and can call the object methods from any thread within the same process.

Creates a new PDF Handler. Each handler is automatically associated with it's own working thread, so that the calling code doesn't have to worry about threading and can call the object methods from any thread within the same process.

As multiple PDF Handler can share the same thread, which is a bottleneck if time-consuming batch operations are running, it must be enforced, that for PDFHandler objects which do perform batch operations, the exclusive flag is set during construction (this ensures, that this will run in it's own thread).
