Opzioni di runtime per la pipeline OCR.

Layout e cell-detection si invocano separatamente:

I flag ❌ reserved / ❌ n/a sono sempre ignorati: il campo esiste per stabilire l’API surface senza breaking changes.

Fields§

§return_word_box: bool

Popola TextBlock.words con bbox per-parola via CTC timestep tracking. Default false (costo negligibile ma disabilitato per back-compat con callers che non usano i word bbox).

Limitazione: le linee verticali (crop_h ≥ crop_w × 3/2) restituiscono words = []; il line-level box_points è sempre valido.

§lang: Option<String>

ISO 639-1 ("it", "en", "fr", "de", "es", "pt") o codice 3-lettere. Oggi ignorato: PP-OCRv6 CH+Latin unico copre tutte le 6 lingue EU. Riservato per routing a modelli per-lingua futuri (Tesseract / fine-tuned rec).

§use_doc_orientation: bool

Corregge automaticamente la rotazione della pagina (0°/90°/180°/270°) prima dell’OCR. Richiede che il classificatore sia caricato via OcrLite::set_doc_orientation_model; senza modello il flag è ignorato silenziosamente. Default true.

§use_doc_unwarping: bool

⚠ riservato. Correzione prospettica pre-det via UVDoc. Modello disponibile (PpStructureModel::DocUnwarp) ma non integrato nella pipeline detect.

§use_seal: bool

⚠ riservato. Riconoscimento timbri circolari (PII nei rogiti notarili). Modello non ancora scaricato/integrato.

§use_formula: bool

⚠ riservato. Riconoscimento formule LaTeX via PP-FormulaNet-plus-L. Modello disponibile (PpStructureModel::FormulaRec) ma non integrato; irrilevante per PII su documenti legali/medici.

§use_chart: bool

⚠ n/a. ChartRecognition non è disponibile come ONNX su HuggingFace. Vedi tools/convert/ per convertire il modello Paddle.
