Description

The operator read_ocrread_ocrReadOcrread_ocrReadOcrReadOcr reads an OCR classifier from a file FileNameFileNameFileNameFileNameFileNamefileName. This file will hereby be searched in the directory ($HALCONROOT/ocr/) as well as in the currently used directory. If too many classifiers have been loaded, an error message will be displayed.

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*)

Name of the OCR classifier file.

Default value: 'testnet' "testnet" "testnet" "testnet" "testnet" "testnet"

File extension: .obc, .fnt

OcrHandleOcrHandleOcrHandleOcrHandleOcrHandleocrHandle (output_control)  ocr_box → HOCRBox, HTupleHTupleHOCRBox, HTupleHOCRBoxX, VARIANTHtuple (integer) (IntPtr) (Hlong) (Hlong) (Hlong) (Hlong)

ID of the read OCR classifier.

Result

If the indicated file is available and the format is correct, the operator read_ocrread_ocrReadOcrread_ocrReadOcrReadOcr returns the value 2 (H_MSG_TRUE). Otherwise an exception will be raised.
