Connect Shapes using Connection Sites in PowerPoint

Introduction

In this tutorial, we’ll explore how to connect shapes using connection sites in PowerPoint using Aspose.Slides for Java. This powerful library allows us to programmatically manipulate PowerPoint presentations, making tasks like connecting shapes seamless and efficient.

Prerequisites

Before we begin, ensure you have the following:

1. Java Development Kit (JDK): Make sure you have Java installed on your system. You can download and install it from the website.
2. Aspose.Slides for Java: Download and install Aspose.Slides for Java from the download page.
3. Integrated Development Environment (IDE): Choose an IDE for Java development, such as IntelliJ IDEA, Eclipse, or NetBeans.

Import Packages

To get started, import the necessary packages into your Java project:

import com.aspose.slides.*;

Step 1: Accessing Shapes Collection

Access the shapes collection for the selected slide:

// The path to the documents directory.                    
String dataDir = "Your Document Directory";
// Instantiate Presentation class that represents the PPTX file
Presentation presentation = new Presentation();
IShapeCollection shapes = presentation.getSlides().get_Item(0).getShapes();

Step 2: Adding Connector Shape

Add a connector shape to the slide shape collection:

IConnector connector = shapes.addConnector(ShapeType.BentConnector3, 0, 0, 10, 10);

Step 3: Adding AutoShapes

Add auto shapes like ellipse and rectangle:

IAutoShape ellipse = shapes.addAutoShape(ShapeType.Ellipse, 0, 100, 100, 100);
IAutoShape rectangle = shapes.addAutoShape(ShapeType.Rectangle, 100, 200, 100, 100);

Step 4: Joining Shapes to Connectors

Join the shapes to the connector:

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

Step 5: Setting Connection Site Index

Set the desired connection site index for the shapes:

long wantedIndex = 6;
if (ellipse.getConnectionSiteCount() > (wantedIndex & 0xFFFFFFFFL))
{
    connector.setStartShapeConnectionSiteIndex(wantedIndex);
}

Conclusion

In this tutorial, we’ve learned how to connect shapes using connection sites in PowerPoint using Aspose.Slides for Java. With this knowledge, you can now automate and customize your PowerPoint presentations with ease.
