Edit OTP properties using Java

Build your own Java apps to modify Built-in and Custom properties in presentation files using server-side APIs.

Modify OTP Properties via Java

Using Aspose.Slides for Java, developers can access and modify the values of built-in properties as well as custom properties. Developers can use DocumentProperties property exposed by Presentation object to access the document properties of the presentation file.

Modify OTP Built-in Properties - Java
Presentation pres = new Presentation("Presentation.otp");
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.otp", SaveFormat.Otp);
} finally {
    if (pres != null) pres.dispose();
}

Add Custom Properties to OTP - Java
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.otp", SaveFormat.Otp);
} finally {
    if (pres != null) pres.dispose();
}
