Create Ellipse Shape Easily with Aspose.Slides .NET

Introduction

In the dynamic world of presentation design, incorporating shapes like ellipses can add a touch of creativity and professionalism. Aspose.Slides for .NET offers a powerful solution for manipulating presentation files programmatically. This tutorial will guide you through the process of creating a simple ellipse shape in presentation slides using Aspose.Slides for .NET.

Prerequisites

Before diving into the tutorial, make sure you have the following prerequisites in place:

• Aspose.Slides for .NET: Ensure that you have installed the Aspose.Slides library for .NET. You can download it from the releases page.
• Development Environment: Set up a .NET development environment on your machine.

Import Namespaces

In your .NET project, start by importing the necessary namespaces:

using System.IO;
using Aspose.Slides;
using Aspose.Slides.Export;

These namespaces provide the essential classes and methods required for working with presentation slides and shapes.

Step 1: Set Up the Presentation

Begin by creating a new presentation and accessing the first slide. Add the following code to achieve this:

// The path to the documents directory.
string dataDir = "Your Document Directory";
// Create directory if it is not already present.
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
    System.IO.Directory.CreateDirectory(dataDir);
// Instantiate Presentation class
using (Presentation pres = new Presentation())
{
    // Get the first slide
    ISlide sld = pres.Slides[0];

This code initializes a new presentation and selects the first slide for further manipulation.

Step 2: Add Ellipse Shape

Now, let’s add an ellipse shape to the slide using the AddAutoShape method:

// Add autoshape of ellipse type
sld.Shapes.AddAutoShape(ShapeType.Ellipse, 50, 150, 150, 50);

This line of code creates an ellipse shape at coordinates (50, 150) with a width of 150 units and a height of 50 units.

Step 3: Save the Presentation

Finally, save the modified presentation to disk with a specified file name using the following code:

// Write the PPTX file to disk
pres.Save(dataDir + "EllipseShp1_out.pptx", SaveFormat.Pptx);

This step ensures that your changes are persisted, and you can view the resulting presentation with the newly added ellipse shape.

Conclusion

Congratulations! You’ve successfully created a simple ellipse shape in a presentation slide using Aspose.Slides for .NET. This tutorial provides a foundational understanding of working with shapes, setting up presentations, and saving the modified files.
