Microsoft Office Visio supporta la manipolazione degli oggetti OLE nel disegno Visio diagram.Aspose.Diagram for Java API.
Manipolare l’esempio di programmazione di oggetti OLE incorporati
ObjectData proprietà delDati Esteri consente agli sviluppatori di manipolare oggetti OLE esistenti in Visio diagram. Questo argomento della guida mostra come gli sviluppatori possono recuperare un oggetto OLE del documento Visio, modificarlo utilizzandoAspose.Diagram for Java API, quindi salvare di nuovo come oggetto OLE in Visio diagram.
