แก้ไขคุณสมบัติ PPTX โดยใช้ Java

Presentation pres = new Presentation("Presentation.pptx");
try {
    // Create a reference to IDocumentProperties object associated with Presentation
    IDocumentProperties dp = pres.getDocumentProperties();
    
    // Set the built-in properties
    dp.setAuthor("Aspose.Slides for Java");
    dp.setTitle("Modifying Presentation Properties");
    dp.setSubject("Aspose Subject");
    dp.setComments("Aspose Description");
    dp.setManager("Aspose Manager");
    
    // Save your presentation to a file
    pres.save("DocProps.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Presentation pres = new Presentation();
try {
    // Getting Document Properties
    IDocumentProperties dProps = pres.getDocumentProperties();
    
    // Adding Custom properties
    dProps.set_Item("New Custom", 12);
    dProps.set_Item("My Name", "Aspose Metadata Editor");
    dProps.set_Item("Custom", 124);
    
    // Getting property name at particular index
    String getPropertyName = dProps.getCustomPropertyName(2);
    
    // Removing selected property
    dProps.removeCustomProperty(getPropertyName);
    
    // Saving presentation
    pres.save("CustomDemo.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
