Modify POTX Properties via C++

Aspose.Slides for C++ lets you read and update metadata in POTX files without Microsoft PowerPoint. Use the DocumentProperties object exposed by Presentation::get_DocumentProperties to change built-in properties such as Author and Title, or to manage custom properties with idx_set, GetCustomPropertyName, and RemoveCustomProperty.

Modify POTX Built-in Properties - C++

auto presentation = MakeObject<Presentation>(u"presentation.potx");
auto documentProperties = presentation->get_DocumentProperties();

documentProperties->set_Author(u"New Author");
documentProperties->set_Title(u"New Title");

presentation->Save(u"updated-presentation.potx", SaveFormat::Potx);
presentation->Dispose();

Add Custom Properties to POTX - C++

auto presentation = MakeObject<Presentation>(u"presentation.potx");
auto documentProperties = presentation->get_DocumentProperties();

documentProperties->idx_set(u"Department", ObjectExt::Box<String>(u"Sales"));
documentProperties->idx_set(u"Project", ObjectExt::Box<String>(u"Metadata Update"));
documentProperties->idx_set(u"Revision", ObjectExt::Box<int32_t>(3));

auto customPropertyName = documentProperties->GetCustomPropertyName(2);
documentProperties->RemoveCustomProperty(customPropertyName);

presentation->Save(u"updated-custom-properties.potx", SaveFormat::Potx);
presentation->Dispose();
