Parfois, vous devez générer des images de Barres de données de Mise en forme conditionnelle. Vous pouvez utiliser la méthode DataBar.to_image() d’Aspose.Cells pour générer ces images. Cet article montre comment générer une image de barre de données en utilisant Aspose.Cells pour Python via .NET.
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 to_image() pour générer l’image de la cellule. Enfin, il enregistre l’image sur le disque.
