To create your first presentation from scratch, follow our step-by-step tutorial:
Manage Presentations
With the DevExpress Presentation API library, you can create new presentations and load existing presentations from a stream or a byte array. You can also merge two presentations into a single document.
Masters and Layouts
Slide layouts allow you to organize slide content. Layouts help maintain consistency throughout a presentation. The Presentation API ships with a set of predefined layouts. You can also create custom layouts.
Slides
You can use a template (Slide Master) to create slides and populate your presentation. You can also reorder, duplicate, and remove existing slides.
Shapes
Presentations use various shapes to display content. Built-in shape types include text boxes, images, geometric shapes, and much more.
Tables
You can create and customize tables in your presentation slides. The DevExpress Presentation API library allows you to add and remove rows and columns, merge and split table cells, and apply various appearance and formatting options.
Themes
Themes are a set of design elements that provide a unified look for your presentation. A theme includes a color scheme, font scheme, and effects.
Backgrounds
You can customize background fill types for slides. Supported background fill styles include solid color, pattern, gradient, and picture.
Headers and footers
Slide headers and footers can display the presentation title, logo, date, slide numbers, and more.
Notes
The Presentation API allows you to manage notes — information about a slide visible only to the presenter, used to add speaking cues or extra details not displayed on the slide.
Export
You can export your presentation to a PDF file.
