Description🔗

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

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.

Parameters🔗

TrainingFiletrainingFiletraining_file (input_control) filename.read(-array) → (string)HTuple (HString)HTuple (string)MaybeSequence[str]Htuple (char*)

Names of the training files.

Default: ''""
File extension: .trf, .otr

CharacterNamescharacterNamescharacter_names (output_control) string(-array) → (string)HTuple (HString)HTuple (string)Sequence[str]Htuple (char*)

Names of the read characters.

CharacterCountcharacterCountcharacter_count (output_control) integer(-array) → (integer)HTuple (Hlong)HTuple (int / long)Sequence[int]Htuple (Hlong)

Number of characters.

Result🔗

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