Mastering Bevel Effects in Aspose.Slides - Step By Step Tutorial

Introduction

In the dynamic world of presentations, adding visual appeal to your slides can significantly enhance your message’s impact. Aspose.Slides for .NET provides a powerful toolkit to manipulate and beautify your presentation slides programmatically. One such intriguing feature is the ability to apply bevel effects to shapes, adding depth and dimension to your visuals.

Prerequisites

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

• Aspose.Slides for .NET: Make sure you have the Aspose.Slides library installed. You can download it from the website.
• Development Environment: Set up your .NET development environment, and have a basic understanding of C#.
• Document Directory: Create a directory for your documents where the generated presentation files will be saved.

Import Namespaces

In your C# code, include the necessary namespaces to access the Aspose.Slides functionalities.

using System.Drawing;
using Aspose.Slides.Export;
using Aspose.Slides;

Step 1: Set up Your Document Directory

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

Ensure that the document directory exists, creating it if it’s not already present.

Step 2: Create a Presentation Instance

Presentation pres = new Presentation();
ISlide slide = pres.Slides[0];

Initialize a presentation instance and add a slide to work with.

Step 3: Add a Shape to the Slide

IAutoShape shape = slide.Shapes.AddAutoShape(ShapeType.Ellipse, 30, 30, 100, 100);
shape.FillFormat.FillType = FillType.Solid;
shape.FillFormat.SolidFillColor.Color = Color.Green;
ILineFillFormat format = shape.LineFormat.FillFormat;
format.FillType = FillType.Solid;
format.SolidFillColor.Color = Color.Orange;
shape.LineFormat.Width = 2.0;

Create an auto shape (ellipse in this example) and customize its fill and line properties.

Step 4: Set ThreeDFormat Properties

shape.ThreeDFormat.Depth = 4;
shape.ThreeDFormat.BevelTop.BevelType = BevelPresetType.Circle;
shape.ThreeDFormat.BevelTop.Height = 6;
shape.ThreeDFormat.BevelTop.Width = 6;
shape.ThreeDFormat.Camera.CameraType = CameraPresetType.OrthographicFront;
shape.ThreeDFormat.LightRig.LightType = LightRigPresetType.ThreePt;
shape.ThreeDFormat.LightRig.Direction = LightingDirection.Top;

Specify the three-dimensional properties, including bevel type, height, width, camera type, light type, and direction.

Step 5: Save the Presentation

pres.Save(dataDir + "Bevel_out.pptx", SaveFormat.Pptx);

Save the presentation with the applied bevel effects to a PPTX file.

Conclusion

Congratulations! You’ve successfully applied bevel effects to a shape in your presentation using Aspose.Slides for .NET. Experiment with different parameters to unleash the full potential of visual enhancements in your slides.
