IEngineLoader Interface

IEngineLoader interface in the ABBYY FineReader Engine API — This interface is used specifically to load and unload the Engine object.

This interface is implemented in FRE for Windows.

This interface is used specifically to load and unload the Engine object. This interface expands the use of ABBYY FineReader Engine in multi-threaded applications. The methods of this interface are an alternative to the existing InitializeEngine and DeinitializeEngine functions. For more information, please refer to the Different Ways to Load the Engine Object section.

This interface is available in the InprocLoader and OutprocLoader objects, which allow you to load FineReader Engine by means of COM either as an in-process server into the current process or as an out-of-process server into a separate process.
