Add Custom Child Nodes in SmartArt using Java

Introduction

SmartArt is a powerful feature in PowerPoint that allows users to create professional-looking graphics quickly and easily. In this tutorial, we will learn how to add custom child nodes to SmartArt using Java with Aspose.Slides.

Prerequisites

Before we begin, make sure you have the following:

Java Development Kit (JDK): Ensure you have Java installed on your system.
Aspose.Slides for Java: Download and install Aspose.Slides for Java from here .

Import Packages

To start, import the necessary packages in your Java project:

import com.aspose.slides.*;

Step 1: Load the Presentation

Load the PowerPoint presentation where you want to add custom child nodes to the SmartArt:

String dataDir = "Your Document Directory";
// Load the desired presentation
Presentation pres = new Presentation(dataDir + "YourPresentation.pptx");

Step 2: Add SmartArt to Slide

Now, let’s add SmartArt to the slide:

ISmartArt smart = pres.getSlides().get_Item(0).getShapes().addSmartArt(20, 20, 600, 500, SmartArtLayoutType.OrganizationChart);

Step 3: Move SmartArt Shape

Move the SmartArt shape to a new position:

ISmartArtNode node = smart.getAllNodes().get_Item(1);
ISmartArtShape shape = node.getShapes().get_Item(1);
shape.setX(shape.getX() + (shape.getWidth() * 2));
shape.setY(shape.getY() - (shape.getHeight() / 2));

Step 4: Change Shape Width

Change the width of the SmartArt shape:

node = smart.getAllNodes().get_Item(2);
shape = node.getShapes().get_Item(1);
shape.setWidth(shape.getWidth() + (shape.getWidth() / 2));

Step 5: Change Shape Height

Change the height of the SmartArt shape:

node = smart.getAllNodes().get_Item(3);
shape = node.getShapes().get_Item(1);
shape.setHeight(shape.getHeight() + (shape.getHeight() / 2));

Step 6: Rotate the Shape

Rotate the SmartArt shape:

node = smart.getAllNodes().get_Item(4);
shape = node.getShapes().get_Item(1);
shape.setRotation(90);

Step 7: Save the Presentation

Finally, save the modified presentation:

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