ocr_change_char — Define a new conversion table for the characters.
ocr_change_char is obsolete and is only provided for reasons of backward compatibility.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 ocr_change_char establishes a new look-up table for the characters. Hereby the number of strings of Character must be the same as of the classifier OcrHandle. In order to enlarge the font, the operator ocr_change_char may be used as follows: More characters than actually needed will be indicated when creating a network using (create_ocr_class_box). The last n characters will not be used so far. If more characters are needed at a later stage, these unused characters will be allocated and then trained with the help of the operator ocr_change_char.
This operator modifies the state of the following input parameter:
ID of the OCR-network to be changed.
New assign of characters.
Default value: ['a','b','c']
If the number of characters in Character is identical with the number of the characters of the network, the operator ocr_change_char returns the value 2 (H_MSG_TRUE). Otherwise an exception will be raised.
