Set `Copy to output directory` to `Always` for all the copied files. You can copy only the language files you are interested in (e.g. all the files that starts with `eng` for English language).\n\n## Configuration\n\n|                                  | Variable name   | Default                                | Description                                                                                                                                                                                   |\n|----------------------------------|-----------------|----------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| **Input PDF file**                   | `inputPdfFile`  | `test.pdf`, included in the repository | The PDF file whose selected page's content will be recognized as text.                                                                                                                        |\n| **Page number**                    | `pageNumber`    | `1`                                    | The number of the page whose content will be recognized as text.                                                                                                                              |\n| **Recognition language**            | `ocrLanguage`   | `\"eng\"`                                | The language used from tesseract to recognize text.
