Set Bullet Fill Format in SmartArt using Java

Introduction

In the realm of Java programming, the efficient manipulation of presentations is a common requirement, especially when dealing with SmartArt elements. Aspose.Slides for Java emerges as a powerful tool for such tasks, offering an array of functionalities to handle presentations programmatically. In this tutorial, we’ll delve into the process of setting bullet fill format in SmartArt using Java with Aspose.Slides, step by step.

Prerequisites

Before we embark on this tutorial, ensure you have the following prerequisites in place:

Java Development Kit (JDK)

You need to have JDK installed on your system. You can download it from the website and follow the installation instructions.

Aspose.Slides for Java

Download and install Aspose.Slides for Java from the download link. Follow the installation instructions provided in the documentation for your specific operating system.

Import Packages

To begin, import the necessary packages into your Java project:

import com.aspose.slides.*;
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

#Let’s break down the example provided into multiple steps for a clear understanding of how to set bullet fill format in SmartArt using Java with Aspose.Slides.

Step 1: Create Presentation Object

Presentation presentation = new Presentation();

Firstly, create a new instance of the Presentation class, which represents a PowerPoint presentation.

Step 2: Add SmartArt

ISmartArt smart = presentation.getSlides().get_Item(0).getShapes().addSmartArt(10, 10, 500, 400, SmartArtLayoutType.VerticalPictureList);

Next, add a SmartArt shape to the slide. This line of code initializes a new SmartArt shape with specified dimensions and layout.

Step 3: Access SmartArt Node

ISmartArtNode node = smart.getAllNodes().get_Item(0);

Now, access the first node (or any desired node) within the SmartArt shape to modify its properties.

Step 4: Set Bullet Fill Format

if (node.getBulletFillFormat() != null) {
    BufferedImage img = ImageIO.read(new File(dataDir + "aspose-logo.jpg"));
    IPPImage image = presentation.getImages().addImage(img);
    node.getBulletFillFormat().setFillType(FillType.Picture);
    node.getBulletFillFormat().getPictureFillFormat().getPicture().setImage(image);
    node.getBulletFillFormat().getPictureFillFormat().setPictureFillMode(PictureFillMode.Stretch);
}

Here, we check if the bullet fill format is supported. If it is, we load an image file and set it as the bullet fill for the SmartArt node.

Step 5: Save Presentation

presentation.save(dataDir + "out.pptx", SaveFormat.Pptx);

Finally, save the modified presentation to a specified location.

Conclusion

Congratulations! You’ve successfully learned how to set bullet fill format in SmartArt using Java with Aspose.Slides. This capability opens up a world of possibilities for dynamic and visually appealing presentations in Java applications.
