]
L’aspect et la sensation d’un texte peuvent être contrôlés en modifiant les paramètres de la police. Les paramètres de police peuvent inclure le nom, le style, la taille, la couleur et d’autres effets des polices. Tout comme Microsoft Excel, Aspose.Cells prend également en charge la configuration des paramètres de police des cellules.
Configuration des paramètres de police
Aspose.Cells fournit une classe, Workbook, qui représente un fichier Microsoft Excel. La classe Workbook contient une collection worksheets qui permet d’accéder à chaque feuille de calcul dans un fichier Excel. Une feuille est représentée par la classe Worksheet. La classe Worksheet fournit une collection cells. Chaque élément de la collection cells représente un objet de la classe Cell.
Aspose.Cells fournit la classe Cell et ses méthodes style et style qui servent à obtenir et définir le style de mise en forme d’une cellule. La classe Style offre des propriétés pour configurer les paramètres de police.
Définition du nom de la police
Les développeurs peuvent appliquer n’importe quelle police au texte à l’intérieur d’une cellule en utilisant la méthode name de l’objet Font.
