Edit PPT properties using Java
Build your own Java apps to modify Built-in and Custom properties in presentation files using server-side APIs.
Modify PPT 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 PPT Built-in Properties - Java
Presentation pres = new Presentation("Presentation.ppt");
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.ppt", SaveFormat.Ppt);
} finally {
if (pres != null) pres.dispose();
}
Add Custom Properties to PPT - 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.ppt", SaveFormat.Ppt);
} finally {
if (pres != null) pres.dispose();
}
