Convert Presentation to PDF with Progress Update

In today’s digital age, converting presentations to PDF is a common requirement, especially in the business and educational sectors. Aspose.Slides for .NET provides a powerful solution for accomplishing this task with ease. In this step-by-step tutorial, we will guide you through the process of converting a presentation to PDF while keeping track of the conversion progress.

Introduction

In this tutorial, we will utilize Aspose.Slides for .NET to convert a PowerPoint presentation to a PDF document. We’ll also implement a progress update feature to keep you informed about the conversion’s status.

Prerequisites

Before we begin, make sure you have the following prerequisites in place:

Visual Studio or any preferred code editor.
Aspose.Slides for .NET library installed.
A PowerPoint presentation file to convert (e.g., “ConvertToPDF.pptx”).

Step 1: Setting up the Environment

First, create a new C# project in Visual Studio or your preferred code editor. Ensure that you have added a reference to the Aspose.Slides for .NET library in your project.

Step 2: Writing the Code

Now, let’s dive into the code that will perform the presentation-to-PDF conversion with progress updates. Use the following source code:

using (Presentation presentation = new Presentation(dataDir + "ConvertToPDF.pptx"))
{
    ISaveOptions saveOptions = new PdfOptions();
    saveOptions.ProgressCallback = new ExportProgressHandler();
    presentation.Save(dataDir + "ConvertToPDF.pdf", SaveFormat.Pdf, saveOptions);
}

In this code snippet, we open the PowerPoint presentation using Aspose.Slides and specify the PDF format for saving. We also set the ProgressCallback property to an instance of the ExportProgressHandler class.

Step 3: Implementing the Progress Callback

We now need to implement the ExportProgressHandler class to handle progress updates during the conversion process. Here’s the code for the ExportProgressHandler class:

class ExportProgressHandler : IProgressCallback
{
    public void Reporting(double progressValue)
    {
        // Use progress percentage value here
        int progress = Convert.ToInt32(progressValue);
        Console.WriteLine(progress + "% file converted");
    }
}

This class implements the IProgressCallback interface and defines the Reporting method to handle progress updates. It prints the current progress percentage to the console.

Step 4: Running the Code

Compile and run your project. You will observe the progress updates in the console as the presentation is converted to PDF.

Conclusion

Congratulations! You’ve successfully created a step-by-step tutorial for converting a presentation to PDF with progress updates using Aspose.Slides for .NET. This skill can be invaluable in various scenarios, such as generating reports or archiving presentations.
