 | Animation is one of the most important parts of the presentations that make them more attractive and meaningful. Aspose.Slides for .NET also allows developers to apply different kinds of animation effects on different kinds of shapes. There are more than 60 pre-defined animation effects provided by Aspose.Slides for .NET. In this topic, we will show how to apply animation effects on shapes and also control their animation order. |
Applying Animation Effects
To apply an animation effect on any shape in the slide, please follow the steps below:
- Create an instance of Presentation class
- Obtain the reference of a slide by using its Position
- Add a Shape to the slide
- Apply a desired Animation Effect on the shape from the list of pre-defined effects. More than 60 animation effects are pre-defined in Aspose.Slides for .NET
- Write the modified presentation as a PPT file
In the example given below, we have added a rectangle shape to the slide with the Spiral effect applied on it.
Example
//Instantiate a Presentation object that represents a PPT file Presentation pres = new Presentation("demo.ppt"); //Accessing a slide using its slide position Slide slide = pres.GetSlideByPosition(2); //Adding a rectangle shape into the slide by defining its X,Y postion, width //and height Shape shape = slide.Shapes.AddRectangle(1400, 1100, 3000, 2000); //Applying an animation effect on the rectangle shape shape.AnimationSettings.EntryEffect = ShapeEntryEffect.Spiral; //Writing the presentation as a PPT file pres.Write("C:\\modified.ppt");

Controlling Animation Order
The above section describes about applying animation effect on a single shape. But, if you want to add more than one shapes and also want to apply animation effects on these shapes, you may want to change the animation order of the shapes added to the slide. For example, in the normal scenario, if you add two shapes:Shape A and Shape B, first Shape A will animate and then Shape B. But, if you want to specify that Shape A should animate after Shape B, you can change their animation order.
To control the animation order of desired shapes in the slide, please follow the steps below:
- Create an instance of Presentation class
- Obtain the reference of a slide by using its Position
- Add multiple Shapes to the slide
- Apply desired Animation Effects on these shapes
- Set the Animation Order of these shapes
- Write the modified presentation as a PPT file
In the example given below, we have added rectangle and ellipse shapes to the slide. Further, we have changed their animation order after applying animation effects on both shapes.
Example
//Instantiate a Presentation object that represents a PPT file Presentation pres = new Presentation("demo.ppt"); //Accessing a slide using its slide position Slide slide = pres.GetSlideByPosition(2); //Adding two shapes to the slide Shape shape1 = slide.Shapes.AddRectangle(1400, 1100, 3000, 2000); Shape shape2 = slide.Shapes.AddEllipse(2400, 1150, 1000, 1900); //Applying animation effects on both shapes shape1.AnimationSettings.EntryEffect = ShapeEntryEffect.Spiral; shape2.AnimationSettings.EntryEffect = ShapeEntryEffect.BoxOut; //Setting the animation order for both shapes. According to below order, shape2 //will animate first and then the shape1 shape1.AnimationSettings.AnimationOrder = 2; shape2.AnimationSettings.AnimationOrder = 1; //Writing the presentation as a PPT file pres.Write("C:\\modified.ppt");
'Instantiate a Presentation object that represents a PPT file Dim pres As Presentation = New Presentation("demo.ppt") 'Accessing a slide using its slide position Dim slide As Slide = pres.GetSlideByPosition(2) 'Adding two shapes to the slide Dim shape1 As Shape = slide.Shapes.AddRectangle(1400, 1100, 3000, 2000) Dim shape2 As Shape = slide.Shapes.AddEllipse(2400, 1150, 1000, 1900) 'Applying animation effects on both shapes shape1.AnimationSettings.EntryEffect = ShapeEntryEffect.Spiral shape2.AnimationSettings.EntryEffect = ShapeEntryEffect.BoxOut 'Setting the animation order for both shapes.
