Shapes

Slides can contain various kinds of Drawing elements. One special kind of drawing is a Shape. A shape has some kind of geometry (GeometryShape.ShapeType) and can be filled and/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 following example shows how you can create and customize shapes using the GemBox.Presentation API.
