— Write a k-NN classifier for an OCR task to a file.
Signature
Description
write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnnwrite_ocr_class_knn
writes the k-NN classifier for an OCR task with
the OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle
to the file given by FileNameFileNameFileNameFileNamefileNamefile_name
. If a
file extension is not specified in FileNameFileNameFileNameFileNamefileNamefile_name
the default
extension '.onc'
is appended to FileNameFileNameFileNameFileNamefileNamefile_name
.
write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnnwrite_ocr_class_knn
is typically called after the classifier
has been trained with trainf_ocr_class_knntrainf_ocr_class_knnTrainfOcrClassKnnTrainfOcrClassKnnTrainfOcrClassKnntrainf_ocr_class_knn
. The classifier
can be read with read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnnReadOcrClassKnnread_ocr_class_knn
.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters

(input_control) ocr_knn →
HOCRKnn, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the k-NN classifier for an OCR task.
FileNameFileNameFileNameFileNamefileNamefile_name
(input_control) filename.write →

File extension: .onc
Result
If the parameters are valid, the operator
write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnnwrite_ocr_class_knn
returns the value 2 (H_MSG_TRUE). If necessary, an
exception is raised.
