Change Text on SmartArt Node using Java

Introduction

SmartArt in PowerPoint is a powerful feature for creating visually appealing diagrams. Aspose.Slides for Java provides comprehensive support to manipulate SmartArt elements programmatically. In this tutorial, we’ll guide you through the process of changing text on a SmartArt node using Java.

Prerequisites

Before you begin, ensure you have the following:

• Java Development Kit (JDK) installed on your system.
• Aspose.Slides for Java library downloaded and referenced in your Java project.
• Basic understanding of Java programming.

Import Packages

First, import the necessary packages to access Aspose.Slides functionality within your Java code.

import com.aspose.slides.*;

Let’s break down the example into multiple steps:

Step 1: Initialize Presentation Object

Presentation presentation = new Presentation();

Create a new instance of the Presentation class to work with a PowerPoint presentation.

Step 2: Add SmartArt to Slide

ISmartArt smart = presentation.getSlides().get_Item(0).getShapes().addSmartArt(10, 10, 400, 300, SmartArtLayoutType.BasicCycle);

Add SmartArt to the first slide. In this example, we’re using the BasicCycle layout.

Step 3: Access SmartArt Node

ISmartArtNode node = smart.getNodes().get_Item(1);

Get a reference to the second root node of the SmartArt.

Step 4: Set Text on Node

node.getTextFrame().setText("Second root node");

Set the text for the selected SmartArt node.

Step 5: Save Presentation

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

Save the modified presentation to a specified location.
