Classe OcrResult

IronOCR retourne un objet résultat avancé pour chaque page qu'il balaie en utilisant Tesseract 5. Cela contient des données de localisation, des images, du texte, la confiance statistique, des choix de symboles alternatifs, des noms de polices, des tailles de polices, des décorations, des poids de polices, et des positions pour chacun :
