GemBox.Presentation is a .NET component that enables you to read, write, edit, convert, and print presentation files from your .NET applications using one simple API.

Header and Footer

Most of slides, except maybe the title slide, contain some kind of header or footer that can present the date and time, a slide number or custom text.

The following example shows how to create and customize master-slide and layout-slide headers and footers using the GemBox.Presentation API.
