Description🔗

read_ocr_class_knnReadOcrClassKnn reads an OCR classifier that has been stored with write_ocr_class_knnWriteOcrClassKnn.

Execution information🔗

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🔗

FileNamefileNamefile_name (input_control) filename.read → (string)HTuple (HString)HTuple (string)strHtuple (char*)

File name.

File extension: .onc, .okc, .fnt

OCRHandleOCRHandleocrhandle (output_control) ocr_knn → (handle)HTuple (HHandle)HOCRKnn, HTuple (IntPtr)HHandleHtuple (handle)

Handle of the OCR classifier.

Result🔗

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