Introduction

In this tutorial, we’ll guide you through the process of adding an assistant node to SmartArt in Java PowerPoint presentations using Aspose.Slides.

Prerequisites

Before we begin, ensure you have the following prerequisites in place:

  1. Java Development Kit (JDK): Make sure you have Java installed on your system. You can download and install the latest JDK from here .
  2. Aspose.Slides for Java: Download and install the Aspose.Slides for Java library from this link .

Import Packages

To start with, import the necessary packages in your Java code:

import com.aspose.slides.*;

Step 1: Set up the Presentation

Begin by creating a Presentation instance using the path to your PowerPoint file:

String dataDir = "Your Document Directory";
Presentation pres = new Presentation(dataDir + "AssistantNode.pptx");

Step 2: Traverse Through Shapes

Traverse through every shape inside the first slide of the presentation:

for (IShape shape : pres.getSlides().get_Item(0).getShapes())

Step 3: Check for SmartArt Shapes

Check if the shape is of SmartArt type:

if (shape instanceof ISmartArt)

Step 4: Traverse Through SmartArt Nodes

Traverse through all nodes of the SmartArt shape:

for (ISmartArtNode node : smart.getAllNodes())

Step 5: Check for Assistant Node

Check if the node is an assistant node:

if (node.isAssistant())

Step 6: Set Assistant Node to Normal

If the node is an assistant node, set it to a normal node:

node.setAssistant(false);

Step 7: Save Presentation

Save the modified presentation:

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