Name
clear_ocr_class_knnT_clear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnclear_ocr_class_knn — Clear an OCR classifier.
Signature
Herror T_clear_ocr_class_knn(const Htuple OCRHandle)

void HOCRKnn::ClearOcrClassKnn() const
def clear_ocr_class_knn(ocrhandle: HHandle) -> None
Description
clear_ocr_class_knnclear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnClearOcrClassKnnclear_ocr_class_knn clears the OCR classifier given by
OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle that was created with
create_ocr_class_knncreate_ocr_class_knnCreateOcrClassKnnCreateOcrClassKnnCreateOcrClassKnncreate_ocr_class_knn and frees all memory required for the
classifier. After calling clear_ocr_class_knnclear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnClearOcrClassKnnclear_ocr_class_knn, the
classifier can no longer be used. The handle OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle
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:
During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.
Parameters
OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle (input_control, state is modified) ocr_knn → HOCRKnn, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the OCR classifier.
Result
If OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle is valid, the operator
clear_ocr_class_knnclear_ocr_class_knnClearOcrClassKnnClearOcrClassKnnClearOcrClassKnnclear_ocr_class_knn returns the value TRUE. If necessary, an
exception is raised.
