read_ocr — Read an OCR classifier from a file.
read_ocr is obsolete and is only provided for reasons of backward compatibility. New applications should use the MLP, SVM or CNN based operators instead.
The operator read_ocr reads an OCR classifier from a file FileName. 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.
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.

Default value: 'testnet'
File extension: .obc, .fnt

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