Parfois, vous devez générer des images de barres de données de formatage conditionnel. Vous pouvez utiliser la méthode Aspose.Cells DataBar.ToImage() pour générer ces images. Cet article montre comment générer une image de barre de données à l’aide d’Aspose.Cells.
Le code d’exemple suivant génère l’image DataBar de la cellule C1. Tout d’abord, il accède à l’objet de condition de format de la cellule, puis à partir de cet objet, il accède à l’objet DataBar et utilise sa méthode ToImage() pour générer l’image de la cellule. Enfin, il enregistre l’image sur le disque.
