Edit PPTM properties using Java

Build Java applications that modify built-in and custom properties in presentation files using server-side APIs.

Modify PPTM Properties via Java

Using Aspose.Slides for Java , developers can access and modify built-in and custom presentation properties. Use the getDocumentProperties method on a Presentation object to access the IDocumentProperties object for the presentation file.

Modify PPTM Built-in Properties - JavaPresentation presentation = new Presentation("Presentation.pptm");
try {
    IDocumentProperties documentProperties = presentation.getDocumentProperties();

    documentProperties.setAuthor("Aspose.Slides for Java");
    documentProperties.setTitle("Modifying Presentation Properties");
    documentProperties.setSubject("Aspose Subject");
    documentProperties.setComments("Aspose Description");
    documentProperties.setManager("Aspose Manager");

    presentation.save("DocProps.pptm", SaveFormat.Pptm);
} finally {
    presentation.dispose();
}

Add Custom Properties to PPTM - JavaPresentation presentation = new Presentation();
try {
    IDocumentProperties documentProperties = presentation.getDocumentProperties();

    documentProperties.set_Item("New Custom", 12);
    documentProperties.set_Item("My Name", "Aspose Metadata Editor");
    documentProperties.set_Item("Custom", 124);

    String customPropertyName = documentProperties.getCustomPropertyName(2);
    documentProperties.removeCustomProperty(customPropertyName);

    presentation.save("CustomDemo.pptm", SaveFormat.Pptm);
} finally {
    presentation.dispose();
}

How to Extract Metadata of PPTM via Java

Call the getDocumentProperties method to get the IDocumentProperties object.
Read or update built-in properties such as Author, Title, Subject, and Comments.
