Description

The operator concat_ocr_trainfconcat_ocr_trainfConcatOcrTrainfConcatOcrTrainfconcat_ocr_trainf stores all characters which are contained in the files SingleFilesSingleFilesSingleFilessingleFilessingle_files into a new file with the name ComposedFileComposedFileComposedFilecomposedFilecomposed_file. The file format can be defined by the parameter 'ocr_trainf_version'"ocr_trainf_version""ocr_trainf_version""ocr_trainf_version""ocr_trainf_version" of the operator set_systemset_systemSetSystemSetSystemset_system. If no file extension is specified in ComposedFileComposedFileComposedFilecomposedFilecomposed_file, the extension '.trf' is appended to the file name. It is not possible to use any of the files in SingleFilesSingleFilesSingleFilessingleFilessingle_files as the new file ComposedFileComposedFileComposedFilecomposedFilecomposed_file.

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

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

Names of the single training files.

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

File extension: .trf, .otr

ComposedFileComposedFileComposedFilecomposedFilecomposed_file (input_control)  filename.write → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

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

File extension: .trf

Result

If the parameters are correct, the operator concat_ocr_trainfconcat_ocr_trainfConcatOcrTrainfConcatOcrTrainfconcat_ocr_trainf returns the value 2 ( H_MSG_TRUE) . Otherwise an exception will be raised.
