Description

read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnn reads an OCR classifier that has been stored with write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnn.

Parallelization

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

FileNameFileNameFileNameFileNameFileNamefileName (input_control)  filename.read → HTupleHTupleHTupleVARIANTHtuple (string) (string) (HString) (char*) (BSTR) (char*)

File name.

File extension: .onc

OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleOCRHandle (output_control)  ocr_knn → HOCRKnn, HTupleHTupleHOCRKnn, HTupleHOCRKnnX, VARIANTHtuple (integer) (IntPtr) (Hlong) (Hlong) (Hlong) (Hlong)

Handle of the OCR classifier.

Result

If the parameters are valid, the operator read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnn returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.

Possible Successors
