PowerPoint

The Powerpoint class, a core component of the OpenXMLOffice.Presentation library, empowers developers to create, open, and manipulate PowerPoint (.pptx) files with ease. Whether generating new presentations or working with existing ones, this class provides a simple yet powerful interface for efficient content manipulation. Once modifications are complete, users can effortlessly save the updated presentation.
