Description

read_ocr_trainf_namesread_ocr_trainf_namesReadOcrTrainfNamesReadOcrTrainfNamesread_ocr_trainf_names extracts the names and frequency of all characters in the specified training files.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

TrainingFileTrainingFileTrainingFiletrainingFiletraining_file (input_control)  filename.read(-array) → HTupleMaybeSequence[str]HTupleHtuple (string) (string) (HString) (char*)

Names of the training files.

Default: '' "" "" "" ""

File extension: .trf, .otr

CharacterNamesCharacterNamesCharacterNamescharacterNamescharacter_names (output_control)  string(-array) → HTupleSequence[str]HTupleHtuple (string) (string) (HString) (char*)

Names of the read characters.

CharacterCountCharacterCountCharacterCountcharacterCountcharacter_count (output_control)  integer(-array) → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Number of characters.

Result

If the parameter values are correct the operator read_ocr_trainf_namesread_ocr_trainf_namesReadOcrTrainfNamesReadOcrTrainfNamesread_ocr_trainf_names returns the value 2 ( H_MSG_TRUE) . Otherwise an exception is raised.
