L_HDOC hDoc;	/* handle to the OCR document. */
L_BOOL bEnable;	/* flag */

Enables or disables the Parallel Recognition Mode of the OCR engine.

Parameter	Description
hDoc	Handle to the OCR document.
bEnable	Value that indicates whether to enable or disable the Parallel Recognition Mode. Possible values are:
	Value	Meaning
	TRUE	Enable the Parallel Recognition Mode. (default)
	FALSE	Disable the Parallel Recognition Mode.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

If the host PC has two processors or a hyper-threaded one, enabling the Parallel Recognition Mode can speed up the recognition process by allowing the two recognition engines to run in parallel.

The OCR engine may use Parallel Recognition Mode when a zone is associated with any of the following recognition modules:

RECOGMODULE_MTEXT_OMNIFONT
RECOGMODULE_OMNIFONT_FRX
RECOGMODULE_OMNIFONT_PLUS3W

To determine whether the parallel recognition mode is enabled, call L_DocIsParallelRecognitionEnabled.

To get information on a particular zone, call L_DocGetZone. The recognition module associated with the zone is found in pZONEDATA. RecogModule, which is updated by the L_DocGetZone function.

If L_DocEnableParallelRecognition is not called within an application, then by default, parallel recognition is enabled.
