Name
read_ocr_class_knnT_read_ocr_class_knnReadOcrClassKnnReadOcrClassKnnread_ocr_class_knn — Read an OCR classifier from a file.
Signature
def read_ocr_class_knn(file_name: str) -> HHandle
Description
read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnnReadOcrClassKnnread_ocr_class_knn reads an OCR classifier that has been
stored with write_ocr_class_knnwrite_ocr_class_knnWriteOcrClassKnnWriteOcrClassKnnWriteOcrClassKnnwrite_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.
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
FileNameFileNameFileNameFileNamefileNamefile_name (input_control) filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)
File name.
File extension:
.onc, .okc, .fnt
OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle (output_control) ocr_knn → HOCRKnn, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the OCR classifier.
Result
If the parameters are valid, the operator read_ocr_class_knnread_ocr_class_knnReadOcrClassKnnReadOcrClassKnnReadOcrClassKnnread_ocr_class_knn
returns the value 2 (
H_MSG_TRUE)
. If necessary, an exception is
raised.
