Add Nodes at Specific Position in SmartArt using Java

Introduction

In this tutorial, we’ll guide you through the process of adding nodes at specific positions in SmartArt using Java with Aspose.Slides. SmartArt is a feature in PowerPoint that allows you to create visually appealing diagrams and charts.

Prerequisites

Before you begin, ensure you have the following:

1. Java Development Kit (JDK) installed on your system.
2. Aspose.Slides for Java library downloaded. You can download it from here.
3. Basic knowledge of Java programming language.

Import Packages

First, let’s import the necessary packages in our Java code:

import com.aspose.slides.*;
import java.io.File;

Step 1: Create a Presentation Instance

Start by creating an instance of the Presentation class:

Presentation pres = new Presentation();

Step 2: Access the Presentation Slide

Access the slide where you want to add the SmartArt:

ISlide slide = pres.getSlides().get_Item(0);

Step 3: Add SmartArt Shape

Add a SmartArt shape to the slide:

ISmartArt smart = slide.getShapes().addSmartArt(0, 0, 400, 400, SmartArtLayoutType.StackedList);

Step 4: Access SmartArt Node

Access the SmartArt node at the desired index:

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

Step 5: Add Child Node at Specific Position

Add a new child node at a specific position in the parent node:

SmartArtNode chNode = (SmartArtNode) ((SmartArtNodeCollection) node.getChildNodes()).addNodeByPosition(2);

Step 6: Add Text to the Node

Set the text for the newly added node:

chNode.getTextFrame().setText("Sample Text Added");

Step 7: Save the Presentation

Save the modified presentation:

pres.save(dataDir + "AddSmartArtNodeByPosition_out.pptx", SaveFormat.Pptx);

Conclusion

In this tutorial, you learned how to add nodes at specific positions in SmartArt using Java with Aspose.Slides. By following these steps, you can manipulate SmartArt shapes programmatically to create dynamic presentations.
