Description

clear_ocr_class_cnnclear_ocr_class_cnnClearOcrClassCnnClearOcrClassCnnclear_ocr_class_cnn clears the OCR classifier given by OCRHandleOCRHandleOCRHandleOCRHandleocrhandle that was read with read_ocr_class_cnnread_ocr_class_cnnReadOcrClassCnnReadOcrClassCnnread_ocr_class_cnn and frees all memory required for the classifier. After calling clear_ocr_class_cnnclear_ocr_class_cnnClearOcrClassCnnClearOcrClassCnnclear_ocr_class_cnn, the classifier can no longer be used. The handle OCRHandleOCRHandleOCRHandleOCRHandleocrhandle becomes invalid.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

This operator modifies the state of the following input parameter:

• OCRHandleOCRHandleOCRHandleOCRHandleocrhandle

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.

Parameters

OCRHandleOCRHandleOCRHandleOCRHandleocrhandle (input_control, state is modified)  ocr_cnn(-array) → HOCRCnn, HTupleMaybeSequence[HHandle]HTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the OCR classifier.

Result

If OCRHandleOCRHandleOCRHandleOCRHandleocrhandle is valid, the operator clear_ocr_class_cnnclear_ocr_class_cnnClearOcrClassCnnClearOcrClassCnnclear_ocr_class_cnn returns the value 2 ( H_MSG_TRUE) . If necessary, an exception is raised.
