Let’s dive in and see how we can achieve this!

Prerequisites

Before we begin, ensure you have the following prerequisites:

  1. Java Development Kit (JDK): Make sure you have JDK 1.6 or higher installed.
  2. Aspose.Slides for Java: Download the latest version from Aspose.Slides for Java.
  3. Integrated Development Environment (IDE): Use an IDE like IntelliJ IDEA or Eclipse.
  4. Basic Knowledge of Java: Familiarity with Java programming is required.

Import Packages

To start using Aspose.Slides, you need to import the necessary packages. Here’s how you can do it:

import com.aspose.slides.*;

import java.awt.*;
import java.io.File;

Step 1: Set Up Your Project Directory

First, you need a directory to store your PowerPoint files.

Create Directory

// The path to the documents directory.
String dataDir = "Your Document Directory";
// Create directory if it is not already present.
boolean IsExists = new File(dataDir).exists();
if (!IsExists)
	new File(dataDir).mkdirs();

Ensure you replace "Your Document Directory" with the actual path where you want to store your files.

Step 2: Initialize the Presentation

Now, instantiate the Presentation class, which represents the PowerPoint file.

// Instantiate Presentation class that represents the PPTX
Presentation pres = new Presentation();

Step 3: Get the First Slide

Next, get the first slide from the presentation where you will add the ellipse.

// Get the first slide
ISlide sld = pres.getSlides().get_Item(0);

Step 4: Add an Ellipse Shape

Add an auto shape of the ellipse type to the slide.

// Add autoshape of ellipse type
IShape shp = sld.getShapes().addAutoShape(ShapeType.Ellipse, 50, 150, 150, 50);

Here, 50, 150, 150, 50 are the coordinates and size of the ellipse (x position, y position, width, height).

Step 5: Apply Formatting to the Ellipse

Now, apply some formatting to the ellipse. We’ll set a solid fill color and a line color.

Set Fill Color

// Apply some formatting to ellipse shape
shp.getFillFormat().setFillType(FillType.Solid);
shp.getFillFormat().getSolidFillColor().setColor(new Color(PresetColor.Chocolate));

Set Line Color and Width

// Apply some formatting to the line of Ellipse
shp.getLineFormat().getFillFormat().setFillType(FillType.Solid);
shp.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK);
shp.getLineFormat().setWidth(5);

Step 6: Save the Presentation

Finally, save the presentation to your specified directory.

// Write the PPTX file to disk
pres.save(dataDir + "EllipseShp2_out.pptx", SaveFormat.Pptx);

Step 7: Dispose of the Presentation Object

Dispose of the presentation object to free up resources.

finally {
    if (pres != null) pres.dispose();
}

Conclusion

Congratulations! You’ve successfully created a formatted ellipse in a PowerPoint presentation using Aspose.Slides for Java. This tutorial walked you through setting up your project, adding an ellipse, applying formatting, and saving your presentation. With these skills, you can now enhance your PowerPoint slides programmatically, making your presentations more dynamic and visually appealing.
