write_ocr_class_knn — Write a k-NN classifier for an OCR task to a file.
write_ocr_class_knn writes the k-NN classifier for an OCR task with the OCRHandle to the file given by FileName. If a file extension is not specified in FileName the default extension '.onc' is appended to FileName. write_ocr_class_knn is typically called after the classifier has been trained with trainf_ocr_class_knn. The classifier can be read with read_ocr_class_knn.
Handle of the k-NN classifier for an OCR task.
File extension: .onc
If the parameters are valid, the operator write_ocr_class_knn returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
