Generieren von Miniaturbildern für bedingte Formatierung DataBars

Manchmal müssen Bilder von bedingten Formatierungs-Datenbalken generiert werden. Sie können die Aspose.Cells DataBar.to_image() Methode verwenden, um diese Bilder zu erstellen. Dieser Artikel zeigt, wie man mit Aspose.Cells für Python via .NET einen DataBar-Bild erzeugt.
Der folgende Beispielcode generiert das DataBar-Bild der Zelle C1. Zuerst greift er auf das Formatbedingungsobjekt der Zelle zu, und dann greift er von diesem Objekt aus auf das DataBar-Objekt zu und verwendet dessen to_image()-Methode, um das Bild der Zelle zu generieren. Schließlich speichert er das Bild auf der Festplatte.
