Deallocation of the memory of an OCR classifier.

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

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

HTuple      OcrHandle,Class,Confidence;
long        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);

If the parameter OcrHandle is valid, the operator ::close_ocr returns the value H_MSG_TRUE. Otherwise an exception will be raised.

::read_ocr
