var textBox = slide.Content.AddTextBox(ShapeGeometryType.RoundedRectangle, 2, 2, 12, 4, LengthUnit.Centimeter);

// Set shape fill and outline format.
textBox.Shape.Format.Fill.SetSolid(Color.FromName(ColorName.OrangeRed));
textBox.Shape.Format.Outline.Fill.SetSolid(Color.FromName(ColorName.Red));

// Create a paragraph with single run element.
var run = textBox.AddParagraph().AddRun("Shows how to create and customize slide transitions using GemBox.Presentation API.");
run.Format.Fill.SetSolid(Color.FromName(ColorName.White));
run.Format.Bold = true;

// Get slide transition information.
var transition = slide.Transition;

// Set the transition type.
transition.TransitionType = TransitionType.Fade;

// Set the transition effect.
transition.Effect = TransitionEffect.Smoothly;

// Slide should advance automatically after 1 second.
transition.AdvanceOnTime = true;
transition.AdvanceAfterTime = 1000;

// Slide should advance on mouse click.
transition.AdvanceOnClick = true;

// Set the transition speed.
transition.Speed = TransitionSpeed.Slow;

// Specify the sound to be played when the transition is activated.
