Name

close_ocrclose_ocrCloseOcrclose_ocrCloseOcrCloseOcr — Deallocation of the memory of an OCR classifier.

The operator close_ocrclose_ocrCloseOcrclose_ocrCloseOcrCloseOcr deallocates the memory of the classifier having the number OcrHandleOcrHandleOcrHandleOcrHandleOcrHandleocrHandle. Hereby all corresponding data will be deleted. However, if necessary, they can be saved in advance using the operator write_ocrwrite_ocrWriteOcrwrite_ocrWriteOcrWriteOcr. The number OcrHandleOcrHandleOcrHandleOcrHandleOcrHandleocrHandle will be invalid after the call; but later the system can use it again for new classifiers.

Attention

All data of the classifier will be deleted in main memory (not on the hard disk).

Parallelization

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

Parameters

OcrHandleOcrHandleOcrHandleOcrHandleOcrHandleocrHandle (input_control) ocr_box → (integer)

ID of the OCR classifier to be deleted.

Example (C)

HTuple      OcrHandle,Class,Confidence;
Hlong        orc_handle;

read_ocr("testnet",&orc_handle);
/* image processing */
create_tuple(&OcrHandle,1);
set_i(OcrHandle,orc_handle,0);
T_do_ocr_multi(Character,Image,OcrHandle,&Class,&Confidence);
close_ocr(orc_handle);

Result

If the parameter OcrHandleOcrHandleOcrHandleOcrHandleOcrHandleocrHandle is valid, the operator close_ocrclose_ocrCloseOcrclose_ocrCloseOcrCloseOcr returns the value 2 (H_MSG_TRUE). Otherwise an exception will be raised.
