write_ocrT_write_ocrWriteOcrWriteOcr (Operator)


write_ocrT_write_ocrWriteOcrWriteOcr — Writing an OCR classifier into a file.


write_ocrwrite_ocrWriteOcrWriteOcrWriteOcr is obsolete and is only provided for reasons of backward compatibility. New applications should use the MLP, SVM or CNN based operators instead.


write_ocr( : : OcrHandle, FileName : )

Herror T_write_ocr(const Htuple OcrHandle, const Htuple FileName)

void WriteOcr(const HTuple& OcrHandle, const HTuple& FileName)

static void HOperatorSet.WriteOcr(HTuple ocrHandle, HTuple fileName)

void HOCRBox.WriteOcr(string fileName)


The operator write_ocrwrite_ocrWriteOcrWriteOcrWriteOcr writes the OCR classifier OcrHandleOcrHandleOcrHandleOcrHandleocrHandle into the file FileNameFileNameFileNameFileNamefileName. Since the data of the classifier will be lost when the program is finished, they have to be stored after the training if the user wants to use them again at a later execution of the program. The data can then be read with the help of the operator read_ocrread_ocrReadOcrReadOcrReadOcr. The extension will be added automatically to the parameter FileNameFileNameFileNameFileNamefileName.


The output file FileNameFileNameFileNameFileNamefileName must be given without extension.

Execution Information


OcrHandleOcrHandleOcrHandleOcrHandleocrHandle (input_control)  ocr_box HOCRBox, HTupleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

ID of the OCR classifier.

FileNameFileNameFileNameFileNamefileName (input_control)  filename.write HTupleHTupleHtuple (string) (string) (HString) (char*)

Name of the file for the OCR classifier (without extension).

Default value: 'my_ocr' "my_ocr" "my_ocr" "my_ocr" "my_ocr"

File extension: .obc


If the parameter OcrHandleOcrHandleOcrHandleOcrHandleocrHandle is valid and the indicated file can be written, the operator write_ocrwrite_ocrWriteOcrWriteOcrWriteOcr returns the value 2 (H_MSG_TRUE). Otherwise an exception will be raised.
