Animation can help to make a PowerPoint document more dynamic and attractive. You can animate both text or shapes on a PowerPoint slide. In this article, I am going to show you how to apply animation effect to text and shapes in PowerPoint programmatically in Java using Free Spire.Presentation for Java library.
Installation
If you use maven, you need to specify the dependencies for Free Spire.Presentation for Java library in your project’s pom.xml file.
<repositories>
<repository>
<id>com.e-iceblue</id>
<name>e-iceblue</name>
<url>http://repo.e-iceblue.com/nexus/content/groups/public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.presentation.free</artifactId>
<version>3.9.0</version>
</dependency>
</dependencies>
For non-maven projects, download Free Spire.Presentation for Java pack from this website, unzip the package and add Spire.Presentation.jar in the lib folder into your project as a dependency.
Apply animation effect to shapes
Free Spire.Presentation for Java supports 151 animation effects, you can see the full list of animation effects in AnimationEffectType enum. The following example shows how to add boomerang effect to a shape.
import com.spire.presentation.*;
import com.spire.presentation.drawing.animation.*;
import java.awt.geom.Rectangle2D;
public class AnimateShapes {
public static void main(String []args) throws Exception {
//Create a Presentation instance
Presentation ppt = new Presentation();
//Get the first slide
ISlide slide = ppt.getSlides().get(0);
//Add a shape to slide
IAutoShape shape = slide.getShapes().appendShape(ShapeType.CUBE, new Rectangle2D.Double(250, 150, 150, 150));
//Add animation effect to the shape
AnimationEffect effect= slide.getTimeline().getMainSequence().addEffect(shape, AnimationEffectType.BOOMERANG);
//Save the document
ppt.saveToFile("AddAnimationToShape.pptx", FileFormat.PPTX_2013);
}
}
Output:
Apply animation effect to text
Animation effect can also be added to text. The following example shows how to add animation effect to a particular paragraph in a shape.
import com.spire.presentation.*;
import com.spire.presentation.drawing.animation.AnimationEffect;
import com.spire.presentation.drawing.animation.AnimationEffectType;
import java.awt.geom.Rectangle2D;
public class AnimateText {
public static void main(String []args) throws Exception {
//Create an instance of presentation document
Presentation ppt = new Presentation();
//Get the first slide
ISlide slide = ppt.getSlides().get(0);
//Add a shape to the slide
IAutoShape shape = slide.getShapes().appendShape(ShapeType.RECTANGLE, new Rectangle2D.Double(250, 150, 250, 100));
//Add text to the shape
shape.appendTextFrame("This example shows how to apply animation to text in PPT document.");
//Apply animation effect to the first paragraph in the shape
AnimationEffect animation = shape.getSlide().getTimeline().getMainSequence().addEffect(shape, AnimationEffectType.FLOAT);
animation.setStartEndParagraphs(0, 0);
//Save the document
ppt.saveToFile("AddAnimationToText.pptx", FileFormat.PPTX_2013);
}
}
