Short description🔗

clear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnclear_ocr_class_knnT_clear_ocr_class_knn — Clear an OCR classifier.

Signature🔗

clear_ocr_class_knn( ocr_knn OCRHandle )void ClearOcrClassKnn( const HTuple& OCRHandle )static void HOperatorSet.ClearOcrClassKnn( HTuple OCRHandle )def clear_ocr_class_knn( ocrhandle: HHandle ) -> None

Herror T_clear_ocr_class_knn( const Htuple OCRHandle )

void HOCRKnn::ClearOcrClassKnn( ) const

void HOCRKnn.ClearOcrClassKnn( )

Description🔗

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

Execution information🔗

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:

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

Parameters🔗

OCRHandleOCRHandleocrhandle (input_control, state is modified) ocr_knn → (handle)HTuple (HHandle)HOCRKnn, HTuple (IntPtr)HHandleHtuple (handle)

Handle of the OCR classifier.

Result🔗

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