Aspose.Slides - Connect Shapes Seamlessly in .NET

Introduction

In the dynamic world of presentations, the ability to connect shapes using connectors adds a layer of sophistication to your slides. Aspose.Slides for .NET empowers developers to achieve this seamlessly. This tutorial will guide you through the process, breaking down each step to ensure a clear understanding.

Prerequisites

Before we dive into the tutorial, make sure you have the following:

• Basic knowledge of C# and .NET framework.
• Aspose.Slides for .NET installed. If not, download it here.
• A development environment set up.

Import Namespaces

In your C# code, start by importing the necessary namespaces:

using Aspose.Slides.Export;
using Aspose.Slides;
                input.Save(dataDir + "Connecting shapes using connectors_out.pptx", SaveFormat.Pptx);

1. Set Up the Document Directory

Begin by defining the directory for your document:

string dataDir = "Your Document Directory";
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
    System.IO.Directory.CreateDirectory(dataDir);

2. Instantiate Presentation Class

Create an instance of the Presentation class to represent your PPTX file:

using (Presentation input = new Presentation())
{
    // Accessing shapes collection for the selected slide
    IShapeCollection shapes = input.Slides[0].Shapes;

3. Add Shapes to the Slide

Add the necessary shapes to your slide, such as Ellipse and Rectangle:

IAutoShape ellipse = shapes.AddAutoShape(ShapeType.Ellipse, 0, 100, 100, 100);
IAutoShape rectangle = shapes.AddAutoShape(ShapeType.Rectangle, 100, 300, 100, 100);

4. Add Connector Shape

Include a connector shape in the slide’s shape collection:

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

5. Connect Shapes with Connector

Specify the shapes to be connected by the connector:

connector.StartShapeConnectedTo = ellipse;
connector.EndShapeConnectedTo = rectangle;

6. Reroute Connector

Call the reroute method to set the automatic shortest path between shapes:

connector.Reroute();

7. Save Presentation

Save your presentation to view the connected shapes:

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

Conclusion

Congratulations! You have successfully connected shapes using connectors in presentation slides using Aspose.Slides for .NET. Enhance your presentations with this advanced feature and captivate your audience.
