Connect Shapes using Connectors in PowerPoint

Introduction

In this tutorial, we’ll explore how to connect shapes using connectors in PowerPoint presentations with the help of Aspose.Slides for Java. Follow these step-by-step instructions to efficiently connect shapes and create visually appealing slides.

Prerequisites

Before we begin, ensure you have the following prerequisites:

• Basic knowledge of Java programming language.
• Installed Java Development Kit (JDK) on your system.
• Downloaded and set up Aspose.Slides for Java. If you haven’t installed it yet, you can download it from here.
• A code editor such as Eclipse or IntelliJ IDEA.

Import Packages

First, import the necessary packages for working with Aspose.Slides in your Java project.

import com.aspose.slides.*;

Step 1: Instantiate Presentation Class

Instantiate the Presentation class, which represents the PPTX file you’re working on.

// The path to the documents directory.                    
String dataDir = "Your Document Directory";
Presentation input = new Presentation();

Step 2: Access Shapes Collection

Access the shapes collection for the selected slide where you want to add shapes and connectors.

IShapeCollection shapes = input.getSlides().get_Item(0).getShapes();

Step 3: Add Shapes

Add the required shapes to the slide. In this example, we’ll add an ellipse and a rectangle.

// Add autoshape Ellipse
IAutoShape ellipse = shapes.addAutoShape(ShapeType.Ellipse, 0, 100, 100, 100);
// Add autoshape Rectangle
IAutoShape rectangle = shapes.addAutoShape(ShapeType.Rectangle, 100, 300, 100, 100);

Step 4: Add Connector

Add a connector shape to the slide shape collection.

IConnector connector = shapes.addConnector(ShapeType.BentConnector2, 0, 0, 10, 10);

Step 5: Join Shapes to Connectors

Connect the shapes to the connector.

connector.setStartShapeConnectedTo(ellipse);
connector.setEndShapeConnectedTo(rectangle);

Step 6: Reroute Connector

Call reroute to set the automatic shortest path between shapes.

connector.reroute();

Step 7: Save Presentation

Save the presentation after connecting shapes using connectors.

input.save(dataDir + "Connecting shapes using connectors_out.pptx", SaveFormat.Pptx);

Finally, don’t forget to dispose of the Presentation object.

if (input != null) input.dispose();

Now you’ve successfully connected shapes using connectors in PowerPoint using Aspose.Slides for Java.
