Name

clear_ocr_class_knnT_clear_ocr_class_knnClearOcrClassKnnClearOcrClassKnn — Clear an OCR classifier.

Signature

void HOCRKnn.ClearOcrClassKnn()

Description

clear_ocr_class_knnclear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnClearOcrClassKnn clears the OCR classifier given by OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle that was created with create_ocr_class_knncreate_ocr_class_knnCreateOcrClassKnnCreateOcrClassKnnCreateOcrClassKnn and frees all memory required for the classifier. After calling clear_ocr_class_knnclear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnClearOcrClassKnn, the classifier can no longer be used. The handle OCRHandleOCRHandleOCRHandleOCRHandleOCRHandle becomes invalid.

Execution Information

This operator modifies the state of the following input parameter:

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_knn HOCRKnn, HTupleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the OCR classifier.

Result

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