Add Shapes to PowerPoint Slides in C# and VB.NET

Presentation slides can contain various Drawing elements. One particular kind of drawing is a Shape.

A shape has geometry (GeometryShape.ShapeType) and can be filled or outlined with ShapeFormat. It also can contain Text.

For more information about drawing types in GemBox.Presentation, see the GemBox.Presentation content model help page.

The example below shows how you can create and customize shapes in your PowerPoint slides in C# and VB.NET using the GemBox.Presentation API.
